[@thagerdorn2009]

When i got my current 04 Suburban, it had a misfire and a P0300 code. Thats it. The worst misfire code you can have. Guy said it needed intake gaskets, which i sprayed around the intake and no change...i then went out and started unplugging coils one by one, until i got to the last one on cylinder one. No change. Replaced coil and plug and ran like a dream. There was the question of "why didnt it throw a P0301 code", but my answer thanks to your channel and growing my diagnostic knowledge, was the circuit was good and intact and the pcm saw the coil getting power and ground, and had control along with all other 7 cylinders. And a spark plug can't throw an engine light code itself because its not electrical like a coil. Thats why we dont arm the parts cannon, we do diagnosing first. Find the problem. Saves so much time and money.

[@ouch1011]

Eric sniffs coil: "it doesn't smell weird" Eric holds coil up to the camera so we can have a sniff too. What a great guy!

To many easy ones coming to SMA...... I like the "" Hunt the broken/corroded wire "" adventures ones, ball joint demolition is good, the tools come out and it gets noisy !!!! Wheel alignments are fun.....and you get paid to do this !!!!!! And we pay you too !!!! It is ALL money well spent for a good education !!!!!! And no student loans, like a community college !!!!! Tracking down a bad module, coil, brain box, or a sensor is a stimulating experience !!!!!! Thank you teacher Eric for your selfless contribution to all mankind !!!!!

After working on a 3.4 Toyota I never want to work on one again. First I did an engine swap. The 3.4 was actually in a 03 Tundra. The donor engine came from a 97 4Runner. Had to change a bunch of stuff over before I could even finish the swap. A day or two after the swap the head gasket popped. Unfortunately the owner had purchased the engine almost a year before so the warranty was long expired. He asked if I could do the head gasket for him, and I agreed. This was one of the weirdest engines I have ever torn down. I ran into all sorts of issues and had lots of bad luck, but I eventually got it back together and its running good again.

[@act2.533]

I'm in the comment section, Eric said I would know what to do.

[@troyfuller35]

Just letting you know mate that you are teaching our younger generation how to run a business properly and look after customers aswell as diagnosing and repairing vehicles. You are extremely good at explaining what you are doing and thinking, the camera work is top notch. Good on ya mate 👍👍

[@htownblue11]

Good stuff. Even though this wasn’t a deeply complex issue, it’s always good to offer content for those just learning the diagnostic process. Keep up the good work.

[@stevenelson8560]

Actually, repairs like that are about as far as I can go, I don't have the skill, tools, or a place to do much but routine and simple stuff. I do enjoy the more complex ones as well, makes me appreciate what mechanics go through.

[@charlesgregory7523]

When my VW had a miss in it I replaced plugs, wires, distributor cap & rotor. Still had the miss. Time to take it to the shop. Mechanic tells me I just need new plugs, wires, cap & rotor. No, I tell him I just did all that. He says give him 20 minutes. 20 minutes later the old Scirocco was purring like a kitten. He replaced my crap with OEM parts. Lesson learned and I use quality parts now.

[@davidszakacs6888]

The bitterness of poor quality lingers longer than the sweetness of low price. (A sign that used to hang at my local quality parts store.)

[@markh.6687]

I missed a very small crack in a distributor cap years ago, which caused my car to run terrible in damp weather. I didn't take the cap off, but the mechanic did to show me why I didn't see it on the car; he could barely see it off the car.

[@scroberts9316]

Another cool diagnosis procedure "tip" and repair. When happy, those 3.4's have nice power and run beautifully.

I wish I was near you, I got a coolant leak (about a gallon between oil changes), never a puddle, and no white smoke out the exhaust. It is perplexing, thinking maybe water pump seal (shaft side) and maybe its only leaking when it is running and hot. I dunno. I've caught so many mechanics goofing around, making me pay for their guesses, that I would gladly pay for your diagnostic skills. Keep up the good work teaching us all how real mechanics work :-)

Nice vid. Merry Christmas to you, Eric, Mrs. O, and the kids. Appreciate your hard work on these videos. I’ve learned a lot over the years watching you.

[@hayacruiser109]

Eric, I guess the customer just wanted a quick fix. Usually you would look at why the coil failed and one possibility would be you find out that the vehicle has a million miles and never had a tuneup. Wide open gapped spark plug. Hope that coil hold out. Love your videos. I’ve learned a lot. Thanks!

[@joemascioni3101]

It's funny how the short and easy "how-to" videos are just so satisfying! Only thing I seen wrong was that the normal "backyard mechanic" (like me) doesn't have a high dollar scan tool to tell him exactly where to look, So I would've had to check each coil 1 by 1 till I found the bad one. Merry Christmas to Eric, Vanessa, and the chitlins!

[@dirtracingfan8742]

A 50 to 100 code reader should’ve gotten you to the same result.

[@paulcoonce2493]

good video. I came to the same conclusion on my tacoma 3.4 with 265000+ miles. P0300 and P0306. Cyl 6 is the middle coil but my cheap little reader didn't exactly tell me that cylinder 3 was the other culprit; just that another cylinder had a problem. Since 3 and 6 worked off the same coil, I replaced the coil. Not OEM (too much $$) at this mileage but a knock off. Check engine light off, no misfire and much quicker starts! Almost positive my MPG will come back! I feel like I have a new truck! It didn't take long to crank before but now it fires in half the time. Basically just turn the key and it starts.

[@johnschuler3269]

Good Job. Thanks for all you do, Eric. As an Engineer who spent years fixing and modifying Radios & Radars across Europe and the USA, I turned sales & marketer of high-end Test Equipment ... I too "Almost failed High School". Now, having sorta-mastered a number of things, including Electronics & (of all things) Linguistics, allow me to say that even your "simple" fixes are helpful for us would-be DIYers. e.g. we get to see where things are and how you take them apart. Even your "Syntax" is helpful; it cements things into our memory banks. e.g. "Alright; we do have no spark" (as in: "Yes we have no bananas". ) I mean would could forget the absence of Spark? 😇 Warm Regards to all, John in the NW

[@stevanrose7439]

My Tacoma had a miss that caused me to think there was something wrong with the driveline. A friend rode with me and said he thought it was a miss. The number 5 plug is the easiest to get to so I started there and lo and behold the plug was bad. I changed it and all the rest and it still runs like a top a year later. 😃

[@jessewebb6183]

Eric! I watch a lot of your videos and being an entry level tech I've learned a lot from your channel(reading wiring diagrams, diagnostics, etc.) Thanks for showing the world your skills! I'm glad I've found your channel, keep up the awesome work!

[@patmowatt2130]

Got the exact same truck and swapped a coil in the fall. Started to get misfires on the #4 a couple weeks ago and immediately thought, well, there goes another coil- truck has 480 000 km on it, so not real surprising. Stuck the new coil in it, fired it up, still got the misfire. Since I had an extra set of wires from a scrapper, I just replaced the #4 wire, and boom, no misfire. I guess I should just check the easy fix first. But at least now I got a spare coil in the scrapper box.

Was a simple diagnosis and fix this time. But still good info and plan on what was wrong with simple straight forward fix.

[@spelunkerd]

I never get tired of SMA videos, even waiting patiently for the next one. Is there any routine you use when you find a bad coil, like inspecting plugs to be sure a bad plug didn't cause it? Or does the scan tool reliably pick up most of the secondary causes?

[@flagmichael]

In this case, he looked for spark from the coil to the plugs. If a plug was shorted he would have had a spark there, but no cylinder fire. Pretty slick.

[@kman-mi7su]

Easy one to assess, I used to own a 2004 Honda Odyssey and did the same thing you suggested, switched the coil pack with another and the misfire jumped to the cylinder that I switched it on. Now the transmission on those Odyssey's well that's another story. I found out why they called them the "glass transmission",

[@ChrisVargasrpht2000chris]

Good video as just a reminder this cold be called process of elimination. You test for power and ground and they were working so next step is the module that gives cylinders 1 and 4 and that might be your issue. Next confirmation would have been to swap one of the known good cool pack but this is where experience prevails. New coil pack fires all cylinders and done. Happy holidays Mr O

Coils are cheap and easy to install. You can get rebuilt injectors (send the old ones back for a refund credit) for very cheap and they are warranted and like new ones from an outfit in CA. Installing injectors means the fuel rail can drip some gasoline... so let a mobile mechanic do it. NO mistakes with any spark are tolerated.
