Wow! You are an awesome teacher. Thank you so much for the great information. We were dealing with a crank no start on my 2008 Toyota 4Runner 4.7 v8 sport edition for 6 grewling months. It was so disheartening. I watched so many videos to help my 62 year old hubby. Don't get me wrong he is a great mechanic. But, hes old school used to dealing with a carburator and no obd2 computer. Trust me, i made him absolutly nuts. Been married for 23 years but, having his wife second guess him was not good for his confidence and for that i am sorry. It's just that my father was dying and we are not well off. I made the mistake of buying the car with 232000 miles on it and not making sure things were maintained like he said they were. Getting older his memory was starting to wither. We or he replaced the bathery, checked the fuses and the 3 relays for the fuel pump, chsnged the gas cap. Cleaned the maf sensor, cleaned the trottle body unnecessary changed the crankshaft position sensor and he dropped the tank cleaned out the tank, changed the fuel filter and found out the fuel pump was ok, changed the spark plugs and still nothing. When my father passed away he left me some money, wait i forgot to add the ignition switch assembly with a set of keys to reprogram. Alot of money, alot and hope was gone. Had 2 codes po113 and po102. Check engine light and a couple others. The toyota dealership quoted me a price of 3500 to drop the tank clean it change the fuel pump assembly eventhough it doesnt say that on the service receipt nor at Toyotas main headquarters where it shows your service done. The installed the ignition switch i bought reprogramed the keys and after about 3 days finnally called me. The wierd thing is the diagnostic info had everything as a pass but the tires which i replaced and they said a " vacume leak that was no big deal and that the catalytic converter was rusty and needed to be reported but no big deal. They initially told me they could fix it in a couple days they were waiying for " the sucky thing for the fuel pump. And an o ring it would be available sometime next week. They wouldnt answer my questions when i asked them what parts were they waiting for? I said the fuel swnding uniti and the o ring. She never responded. I know its supposed to be a complete unit replaced. Meanwhile since she never would answer the phone or my text i called toyota. Of course they heard about it and sent me sn kinda nasty email i ignored it. Then on sunday the car was ready. Three days later. Even though they were waiting on parts to arrive in about a week. I cant help but feel scammed. They didnt even take the price of the diagnostic off the price they added it. Told me 1700 to drop the tank and replace the fuel filter was rhat much. To replace the ignition switch went from 1700 but since i had the part from florida at another dealership the took that down to 800. Then 189 for the fuel injectors cleaned and the butterfly thing cleaned. Sorry i forgot the name because i know nothing about cars, i just watched videos over and over. Throttle body. Thats it. Clean the throttle body for 199. All equaling 3600. I couldnt figure out how she did her math. Trust me i asked. Hense my call to Toyota headquarters. I Just wanted my car fixed nowcheck engine light back on with vsc off and squiggly line light. Im thinking cat. My question to you is how do you feel about catclean. I'd rather things and then I read bad things and I know nothing. Sorry it was so long. You seem like an honest gentleman that really calmed me. So much good info. I really live the suv. But, im so afraid they put little bobby traps in there and little by little i will pay again for calling toyota. I hope we dont need a new cat. We are now getting the dreaded po420 code. The car was light free then when my father passed away he drove from Louisiana to florida. Lights came on. I read somewhere that cats need to be warmed up to read properly and the fact they were about 600 miles warmed up that it was that. The cat is the reason for the check engine the vsc off and the sqiggles. I will never go back to that Toyota dealership ever again. I think its a shame because they lost someone that could have been a lifetime customer. It also makes me sad that human being could treat each other with such distain and in this world of technology , lack of morality, lack of the golden rule teachings and the religion of be good in your heart thats all that matters is gone. Texting a customer is apauling and shifty. Have the guts to use your voice before we lose sight of this beautiful world where life is so precious and short. I am 57 my dad was only 82. But , i still felt 12 around him. He knew how to do everything. I will forever be changed by his loss. People like you are one in a million. The way you teach is inspiring. Thank you.

Try changing Cabin Filter if you have rough idle issues when turning On AC. I have a 230K mileage lexus is250 that has a P0113 misfire and rough idles on R/D/AC On.

Great video. I seen a guy clean his IAC with it still mounted. He removed the tube where it vents into the crankcase. While plugging the hole where the tube was attached with his finger he sprayed carb cleaner down through the throttle body into the IAC until it started to break up the carbon buildup. You can also tear the whole throttle body off and remove the IAC but, if you don't have to why? Thanks again.

Here is my situation: There is no check engine light and the car starts fine but has rough idling in hotweather or after the 1st trip. So if you drive in the morning to get gas there are no issues, but after you start up your car again to leave the grocery store (2nd trip within a short amount of time) it starts idling low or bad. The 2nd trip situation seems to fade with extended time. So if I go to work and then work my 8 hour shift and then leave, I dont notice it much unless its hot weather out. Other things to note. My "charging system" failed when i had it tested, but my battery passed. I took out my alternator and my alternator passed the independent/isolated test on the machine at 2 auto stores. I have an AC adapter that reads voltage and at stops/red lights it drops below 12v. I will check the air lines though but wondered if there are other things to check.

I really hope I can figure it out.

[@thomaswilsonsr.9206]

A misfire could be from a stuck open valve. In modern cars, you would just have a bent valve or it would have dropped down. You could also have a head gasket not torqued all the way, and you've lost compression. Rocker arms being too tight can push on the lifter, when set at an undesired valve lash. Spark plug could be loose in the hole, and little to no compression could be found. Bad piston rings could produce little to no compression. Always take off the valve cover and watch the rockers move.A bad harmonic balance, flywheel, or flex-plate could lead to knocking sounds, as well as unbalanced vibrations. A vacuum leak could cause vibrations (un-metered air entering intake manifold / carburetor).

[@mysterydude1]

Great video but just a tip, check your idle air control valve first. More often than not this is the culprit and by starting with this first you may potentially save a lot of time and effort trying to find the problem.

[@macknumber9]

How How do you even check the IAC? I removed mine and I cleaned it out But that doesn't really help if there's an underlying electrical issue that needs to be Resolved

[@mysterydude1]

@@macknumber9 To check whether the idle air control valve is functioning properly, start the engine and let it run for about 10 to 15 minutes. If the valve is functioning correctly, the engine will sound good and the idle will be steady versus too high, too low, or inconsistent. Additionally, using an ohmmeter, measure the resistance between pins 1 and 2 on the (IAC) valve. Resistance should be 10 - 14 ohms. Depending on the model this could even be 7 - 25 ohms. Check the specifications for your specific vehicle. If you can't tell by listening or don't want to mess with learning how to measure ohms and all that stuff, just simply replace it with a new one. They can be expensive depending on the vehicle. I can get mine for about $30 online. I have seen them for $100 or more on other cars. Either way, these things usually last for a long time, so by replacing it, you'll be doing yourself a favor in the long run. If money is an issue, you could always buy one, install it and see if that fixes the problem. If not, then as long as you're careful with it, you should be able to return it and get your money back. Most car parts stores won't let you return electrical parts if they have been installed. So just try to not scratch, ding, or otherwise make it obvious that it was installed and you should be ok.

[@macknumber9]

@mystery dude yeah my car idles perfect it does what it should do when it starts up rpms are about 1200 like they should be to help the car warm up and then they drop gradually....sometimes as they drop it does slightly surge up but it ends up going down and idling at a steady rpm that is around 700....my issue is I feel these little slight shakes...they come and go and I feel them more in park than I do in drive so I don't think it is mounts

@@macknumber9 honestly the shake could be anything. It could be the fan kicking on, bad spark plug or wire, or even a sticking valve.

I just had my exhaust on a 2005 Mercury Grand Marquis worked on, by a custom exhaust specialist. The reason I took the car in is because the hangar broke and pipe began rubbing against the inside of the car. I also knew I had an exhaust leak most likely in the manifold. But there was no check engine light on and car started up beautifully, drove beautifully despite the ticking noise when accelerating. The mechanic also fixed the suspension, unrelated but definitely needed. I didn't replace the exhaust manifold because it is too big of a job and the mechanic was able to weld the tube as best he could, leaving only a very small leak. No more fumes, or ticking but now the car is vibrating during idle and check engine light on. I took it back it was for emissions and he said everything else seemed good, no misfires. But now the car is having trouble starting at times. I'm just gonna take it somewhere else which I would have done, but I heard these guys were cheaper because they can weld. It could be unrelated, but it seems too coincidental to me

[@steeloned]

Informative and to the point. Wish my mustang plugs were as accessable as yours because that's what I suspect is contributing to my shaking while in gear with acceleration lacking in power. Wouldn't the plug wires also be suspect?

Just an important thing to know: Seafoam should ONLY be used on regularly maintained/ late model cars (newer ones), otherwise it can cause too much space between the pistons and bore, leading to burning oil. It'd be great before an engine rebuild on an old car, but if you have an older car - and you're not planning on doing an engine overhaul - then stay away from it. Everything will leak afterwards.

If you replace plugs and coils and other parts, and find your engine light still comes on after a while, or shortly after replacing parts, the real problem is that the main computer needs to be reprogrammed. I spent about 800 dollars replacing plugs and coils twice, mechanics replacing parts, etc. all which did not solve the problem. You may also notice the car jerks when you accelerate, as though you have a transmission problem. The real problem is not the transmission. The main computer has to be reprogrammed. Another symptom is the air conditioner compressor will shut down; you will not have air conditioning. That is to protect the AC compressor. Once you have the main computer reprogrammed, the AC compressor will work. I went to 6 different Ford dealers in Miami / Ft. Lauderdale, and none of the six mentioned a thing about reprogramming the main computer. I was told by several dealers, not knowing about the main computer at that time, that "there's nothing you can do." One Ford dealer had the car a full day, and said I might have to replace the main computer, and that they cant do that , because Ford no longer carries them. I finally found a Ford dealership (Pines Ford) who said they could reprogram the main computer. Regular scanners can't reprogram your computer. It requires a bi-directional scanner, a Ford subscription for the scanner, and someone who knows the procedure required to reprogram. For that reason, IMO, it's best to take it to a Ford dealer who can reprogram the computer, and they can also check to make sure your plugs and coils are all functioning correctly. They can also check for vacuum leaks, vacuum hoses that may need replacing, bad coil connectors, etc. Not cheap, but better than paying a mechanic to replace parts that won't fix the problem.

[@bren7942]

After watching this I felt like i could be a mechanic because you explained everything so perfectly! Question though, I've had someone look at it and they said the belt tensioner might need to be replaced. I phoned another mechanic, without having looked at it, they said it could be the alternator. Here are the symptoms my car is experiencing: 1. vibrations while idling 2. vibrations while using electronics (windows, A/C, etc) 3. random dashlights flashing (ie: passenger air bag, cruise, cruise set, and more recently battery light and ebrake light). From these symptoms would you be more inclined to say its the alternator, battery or belt tensioner? Or something I didn't mention?

[@4x4ismystyle26]

Sounds like you are definitely low on power. If it were me I'd take it down to your local auto shop, most will test the battery and alternator for free. I suppose a tensioner could also cause a lack of power if it wasn't keeping the belt tight enough to properly spin the alternator but that's a bit less likely. You can always some back and check that afterwards.

[@BudgetMechanicHawaii]

Almost positive your alternator is failing. You can get it check free at many auto parts store

[@chiledoug]

I had that happen the only 2 things i could find were low oil and it seemed it wasn't heating up like it usually does(it was cooler that day) It is an 78 E 250 with no choke.i topped off the oil seems to run fine now My question is will low oil cause this..

[@chiledoug]

been driving it a while since then runs great

[@codynicholson8999]

Yes low oil will cause this. I bought a ford truck that had a oil leak that I didn't know about, and after driving it for about a week it started shaking and vibrating at idle and driving rough. I checked the oil, and it was really low. So I added oil to it, and it drove fine afterwards. An once I fixed the oil leak it never did it again, hope this helps.

[@AndreThomasINC]

You mentioned spark plugs but didn't talk about spark plug wires which can need replacing on older cars. My 1997 Toyota Corolla needed replacement of both spark plugs and the spark plug wires. Problem fixed!

[@nickcabrera663]

Thanks for these great tips! Trying to troubleshoot an intermittent engine code p0171 on my corolla and no idea what I'm doing. It popped up a few times after I did something silly like not putting the oil stick all the way in, gas cap, air filter box not secured after changing but now it's staying on and trying to figure out what it is..

[@coreyholmes2229]

Most likely intake manifold gasket. If you have a obd-II scanner of your own, you can pull up the long and short fuel trims on cold start up. If they’re +20 on either one it throws the code because it’s trying to overcome the lean condition. Spray starter fluid around the intake manifold and if the RPMs change, it’s the gasket. Really easy to change and only $5 part. Hope that helps. If not that, check your air intake line for vacuum leak.

It's easy to see cracked or broken motor mounts, but sometimes they're saggy or hard as rock so also check for that. Sometimes people will just do a visual without checking for anything else. You can poke them with a screwdriver to check for stiffness or even too soft.

[@gianpaolodepaor4755]

You don’t mention the fuel filter, I’m not very sure about it, but it can be also a factor?

[@mannys9130]

Yes, but fuel filters typically show symptoms at high loads first when lots of fuel volume is needed. Then the poor performance gradually creeps down to low speeds and low loads as it plugs up more and more. Most vehicles now no longer have replaceable fuel filters. The only filter is the felt suction sock piece on the intake port of the fuel pump which is submerged in the fuel tank.

[@blissfuljoy6049]

What could cause a very random ( possibly caused by hot weather) jolt or grunt sort of sound/movement? Sometimes it happens multiple times sometimes once. Never rhythmic and always at idle in drive.

Did it fix the way your car was running before? Having the computer reprogrammed? Cause I have changed the coils and plugs and a lot more on my Ford Mustang and it’s still rough idling and I don’t know what to do

[@tompastian3447]

@@aaronortiz5753 Thanks for your question Aaron. Absolutely, find a Ford / Lincoln dealer that offers the service of reprogramming your computer. In South Florida, I was very surprised as to how a good number of Ford Dealerships seemed to have no clue about reprogramming the main computer. One dealership near my house had the car a full day and never did anything to the car. They said it probably needs a new computer and that since Ford no longer sells a replacement, I was out of luck. I got a similar response from several other dealers. Pines Ford in Pembroke Pines FL does reprogram main computers. I had it done twice. Before the second reprogramming, I specifically asked them to change any coils that were not replaced on the previous visit, which completely solved the problem. They replaced a vacuum hose and one coil connection as well. If you find a Ford dealer that tells you the main computer can't be reprogrammed, or that they do not do that, find another Ford dealer. My guess is that most general repair shops don't have bi-directional scanners. Auto parts stores will rent or sell scanners, but these are generally just for diagnosis. They can detect a problem with a particular cylinder misfiring. They do not however have the capability to do much more to your computer than to shut off the engine light. Once that light goes off, it will eventually go back on if the problem has not been solved. If your AC compressor has stopped working, having the computer reprogrammed may reactivate the AC compressor. Bidirectional scanners are a more expensive scanner, which requires a Ford subscription. This type of scanner has the ability to re-program the main computer. It probably requires a specific process, so it's not the type of thing I would purchase myself, or attempt to do myself. A Ford dealer who reprograms computers should have all the right equipment and be familiar with the process involved. BTW, I got a lot of this information from a Ford Master Tech. I told him how I had replaced a lot of parts, coils, plugs, and carburetor parts, but my engine light would still come back on, and the car had jerky acceleration, etc. He immediately mentioned having the main computer reprogrammed. He also said that the AC compressor shutting down is typical. The main computer shuts the AC compressor down to protect it until ignition problems are resolved.

[@aaronortiz5753]

@@tompastian3447 Thank u man! I appreciate it. I did take it to a dealership already but they told me that I need a new computer, they didn’t say anything of reprogramming so I’m guessing they don’t do that. And yeah also my A/C isn’t working which was really weird to me since the A/C doesn’t really have to do anything with the engine acting weird, but now that u are telling me it’s because of the main computer then all makes sense. I did get diagnostics and it said u had like 3 misfires and did everything I could to fix it but it’s still the same. I well make sure to find a dealership that will do the reprogramming. Thank u so much for responding!

[@tompastian3447]

@@aaronortiz5753 Yes, find a more competent dealership. You might try looking up Lincoln Dealers in your area. Just a stab in the dark, but maybe since they service the higher end Ford vehicles, they might be more likely to have Ford's correct diagnostic equipment. Another thing about people who tell you that the main computer may need to be replaced, even if that was true, a replacement computer also has to be programmed after it's installed. You can't just stick in a new computer, or pull one out of a junk yard from another vehicle and expect the car to run right. What city and state do you live in ? VERY IMPORTANT, when they reprogram your computer, it requires 2 ignition keys. Be sure to supply the dealership with two keys, or they may have to charge you to make a second key.
