This guy is a genius, I’m a DIY person and my car ran rough at idle with no check engine lights at all. The car was also very very snappy when you would accelerate so I cleaned the throttle body and I can’t even feel the motor at idle and it’s a very easy smooth takeoff instead of a jerky take off.

[@spelunkerd]

That's good advice, I didn't know I could cause harm with the cleaner. Some shops are selling an intake clean for engines with direct injection, which basically sprays a mist of cleaner into the intake, while running, to loosen caked debris on the sidewall leading to the top of the intake valve. I've often wondered if flakes of hard carbon might cause a problem inside the cylinder if they are swept in with the cleaner. It seems a little safer to wait for a time when the intake is off to do that kind of intake cleaning, where one can have a little better control.

[@johnharrison5656]

That’s a valid concern, and I agree that removing the heads, and doing a valve job is best! The hot flakes falling into the cylinder from the valve, would cause premature detonation of the fuel. By spraying the cleaner, you really don’t know how much of the carbon is removed. Mostly, it would loosen the deposits enough to cause knock more frequently leading to a host of other potential issues. It might could be beneficial if it was done as a preventative measure, but I definitely wouldn’t try it on a vehicle that is already having problems from carbon buildup. With direct injection, the best offense is a good defense. Always run higher octane gas from the start.

[@SoCal_ayyayyron]

I like that you are using an M4 cleaning brush. That is a classy touch! I'm going to repurpose mine to use with my throttle body.

[@terrapinflyer273]

Be careful! W some vehicles people have told me to never move the butterfly valve manually. This can somehow screw up the throttle body sensor or damage it because of the way it's built and takes readings. You may also need to perform an idle reset after any of this. Which sometimes can be a quick DIY procedure involving a gas pedal and ignition combo, followed by a bit of highway driving. I'm taking mine to the shop lol.

[@AutoRepairTips757]

As long as your car is in the off position you should not have any issues I’ve done all kinds of cars doing it this way. as long as that keys off You should not have a problem

[@All_praise4Allah]

It wont hurt it. Ive always done it with all vehicles. As long as its off. If its running have someone press the accelerator or use your finger to pull the cable

[@austindacosta6498]

Here’s the thing, if it’s a older car and it has a manual throttle body with the cable you can pull on to increase the idle speed and a IAC tps and all that crap on it, it’s okay to handle with your hands. If it’s a newer model and has a all electric throttle body where it’s just the black computerized part on the side, and that’s it. Then do NOT stick your hand in it. Even with the battery unplugged those things can hold power, and there have been stories of them flipping out when being touched and snapping shut, which would take your fingers right off

[@jlalvarado024]

I would remove the throttle body before doing any cleaning because you don't want any debris going into your engine causing other issues.

[@benanza9]

I thought so too

[@KronicDaydreamZ]

That would make sense

[@AutoRepairTips757]

removing the throttle body is an extra step that's not needed, the ring that normally builds up can be wiped off with no issue. and if there is any debris they are so micro that it would not hurt anything, by doing it this way you can get 99.9% of it with out removing it.

[@AutoRepairTips757]

I’m glad it helped

[@orinmangar2333]

If you gently move the throttle plate/butterfly, you should do no damage. Just don't let it snap back after you fully open it. Also, I would use a plastic tool to hold it open, not a metal screwdriver.

[@garyr7027]

Some throttle bodies have a coating that mechanical tools can scratch up. Do NOT clean you throttle body like this. I would never recommend using anything abrasive on a throttle body. The coating is there to prevent aluminum corrosion that can hang up the throttle plates. Use only throttle body aproved cleaners. And if you're worried about the internal engine parts, removed the throttle body then clean it. Plus, not all throttle bodies are the same, some have air bypass solenoids for idle, which often also gets plugged up with carbon and require cleaning.

Thanks, I have a 2011 Buick enclave. I bought it at auction in April. It took the state a month to get back with title. So now I have tag, title, insurance. And have thoroughly enjoyed prowling around the neighborhood late night to get a feel for it. So, the problem. The what appears to be usual abs light. So, I have not gotten around to figuring which wheel the error is coming from. Back to the low idle. I was coming back from an event on the highway, on exiting back to city streets. A wide gentle curve from exit to city street and at the absolute worst possible time the engine died and the pig nearly coasted into a lane of cars waiting at the light. I quickly threw it into neutral and hit the key, it started up with a brake light I had not seen before on the dash. Got back to the house off loaded some groceries and took a well deserved whizz. Started the Buick back up again. No brake light. I think I got off extremely light. Anyway, I moved that hose out the throttle body and mass air flow sensor thing up from "around to it" to first thing in the morning before it gets hot out. I think I am about due for a cheap OBDII reader to arrive tomorrow as well. Added to the mix, I had dumped a jug of crc catalytic converter cleaner on top of a quarter tank, did the obligatory 15 miles of normal driving. Filled up and went to the event, stopped at a store and got a bag of late night stuff. Hit the road and had the Buick jump up and shout boo at me. I am interested in what I will find with an OBDII code reader.

[@AutoRepairTips757]

I’m curious to what you’ll find. Give us an update once your scanner comes in.

If the problems persist beyond this point try tightening the throttle cable to keep it from dropping below 1000rpm but with the AC on it will raise rpm initially then drop it as the ac motor runs.

Haven't sorted it. Clean the mass air, any vacuum leaks- I haven't looked properly yet. There is this large rubber chamber, like a dampener/ equaliser, that has several air intake pipes to it and an out, that is perishing. It only took a few years from a new car to start doing this. I then went to get a dealer part and "don't have one". Order it then:- they just ignored me really. Nothing happened. No call back. I haven't been back. Off Scotty Kilmer- To reset the computer if you need to, only use a 1 ohm, 10W resister between battery leads. ONLY when you have already disconnected those vehicle's 12v battery terminal leads prior ONLY!!! (Never short out between these disconnected battery without the resister- otherwise you'll screw your computer, -just adding.

You have a regular can of throttle body cleaner sitting around the garage..

[@ericg4915]

A good product is seafoam spray. Not the stuff that goes in the tank, they have a spray can that is an intake cleaner and upper engine cleaner. You take the clamp off right before the throttle body, put in the straw and then tighten everything back up and spray the whole can until it's empty while car runs at 2000 rpms. It does a great job at cleaning the throttle body and the engine, I do it every year as a preventive measure so my throttle body never gets to the point that it has to be cleaned by hand. It's just an all around good way to keep the motor clean

[@florenbaron7111]

I hope this fixes my issue and I hope I can get my TB off; I'm not good with cars and I hate working on them. I just clean my MAF last night and it didn't make any difference at all, but I still have to do the plug pull test I just found out about where you pull the connector while the car is running and if there's no change then your sensor is just bad and needs replaced. If the TB doesn't do it, then based on other vids, I'll be checking the IAC, vacuum leaks, pcv, maybe the egr. My car currently idles fine when cold but has low power for driving, but when the engine warms up, it drops from 1500 rpm to 500 rpm and runs very rough, and then when I put it in gear it wants to stall and when driving I have little to no power and can get stuck in traffic and can't go up hills, basically undriveable. But also a clue is that this was a gradual problem that developed over years and only recently just kind of took a nose dive. I'm sure that narrows it down but without talking to someone, I don't know what. Unfortunately my problem is compounded with being homeless, broke and unable to work with this undrivable car. If I manage to get this issue fixed then I still need a water pump and timing belt and can only drive the car for 20 minutes before the fluid leaks out, and then it needs full break work. Hanging by a thread here and now winter is setting in so no more warm days for working on the car.

Hi I have a 2007 Liberty 3.7L V6, 117,000 miles. Owned it since 67,000 miles. It operated perfectly for the first 30,000 miles and then it started getting a #1 Cyl misfire code P0301. It also seldomly gets a #1 cyl fuel injector circuit open P0201. It must be a very mild fault as the misfire freeze frame data shows it always happens at less than 350 rpm and when cleared it comes back immediately at next startup, cold or hot. So it seems to only happen once on startup as its moving up to regular idle speed. The miss isnt noticeable when driving or idling. Its getting 15.5 mpg fuel mileage. Doesnt burn oil. Doesnt smoke. Has great power. I've changed plugs and coils but no difference. Cleaned air intake, air filter, and ran cleaner through system. I've cleaned and inspected the injector plug and all wires but no difference. Dry / wet compression test of #1, 3 and 5 cylinders all read good: 160 / 175 psi. I'm wondering if there's a mild wire defect for that injector, or just a flakey connection somewhere. Has anyone tried to use a new set of compatible gauge wires and run them to a place closer to the injector control? I can't see where the wires go though. I'm not sure if I should just live with this, or troubleshoot it more. I don’t care about the engine light as we don't have emission requirements. Now that I know the compression is good, I'm not so worried about it. Any suggestions of what to do next? Thanks!

I'm having the same issue with my 2014 Mitsubishi outlander. The car takes a min the start going plus at stop lights or sign, my rpm will drop to 500 or lower and bounce back up to around 900 and slow goes down. So might have to try this.

[@dritz3288]

I have the same vehicle, did this work?

[@Andrei-cp5jr]

Mine has a rough idle after I give it a bit of gas and then it goes back to 900 rpm after oscillating between 1250 and 500 a couple of times. The engine shakes a bit, too and I think I even heard a misfire after revving it to 3000 rpm. It had a blown vacuum hose which I changed. The rough idle was even more pronounced before that. I don't know if it's ignition, fuel system or the throttle body. I'll check the throttle body first. The spark plugs, distributor cap and spark cables are new (were also broken). I'm worried it might have something to do with the ignition, because the car has other electrical problems involving the lights.

Check for a vacuum leak or maybe an intake hose with a crack somewhere also check at the mass airflow sensor for any leaks

Was having rough idling ( basically high rpm around 2k ) issue with my Chevy Kalos 1.2.. Got it cleaned thoroughly by opening the TB from its Mount. After that the above problem was fixed to some extent however, I've noticed check engine light post cleaning and there is also a jerkyness while accelerating especially in low RPM ( say about 1.2k ). Any idea what could be the reason behind it and how to solve it ?

[@fredericksville3457]

Normally when you clean a dirty throttle body your supposed to do a idle relearn on the car where you basically restart it because the car adjusts to a dirty TB and once you clean it it doesn't have to open as much but the car doesn't know that. So just look up how to do a idle relearn on your car and that should fix your issue I think

[@fredericksville3457]

Also don't go and get your check engine light checked and see what the code says

[@AutoRepairTips757]

@@fredericksville3457 a relearn is not needed in this procedure, when you start up the car the ecm will make any adjustments IF NEEDED.

@@AutoRepairTips757 Okay then what could be Indrajit's issue ?

[@BTKKILLER1]

@@elypeachy3296 disconnected the black and red battery make sure the head lights are on and tie both cables together for 15 to 30 minutes so it can reprogram . Then put the cables back on the battery turn of the headlights and take it for a drive on the hwy. That should fix the problem let me know how it went

[@katelyngautreaux6738]

Some vehicles require a relearning process at dealerships , that wasnt mentioned & also you supposed to take it off to clean it believe

[@johnjohn6332]

Does it work also on w204 mercedes 2010 model..my car also an rough idle when you stop

[@sufyanumar4663]

Would this work on an audi a4 2.0tdi you 2009 model

[@albertcabello7855]

Can a 1in upper intake manifold spacer cause rough idle and a strong exhaust smell?(3025.0L HO

[@MrDaneis]

Clean the mass air flow sensor while you're in there as well. If the throttle body is filthy I guarantee the MAF isn't looking good.

[@nilsonc93]

Did you clean it while the car running or was it off? My avalanche is having idle issues.

[@AutoRepairTips757]

I clean them with the key off and I squirted the cleaner on the brush or the rag. I do not squirt inside the intake.

I have a ‘13 equinox, replaced a multitude of things (over 4K of work) my car has a rough idle when I start it up and sometimes stalls and now when I stop at lights, it’s at about 500rpms. Still not sure what it is. I’m at a loss and can’t keep putting money in this thing.

[@HaggisMuncher-69-420]

My car today just came out of the garage after 2 weeks for a P0299 turbo issue. Not only did they not fix the issue but they've now left my car roughing rough at idle..............

[@AutoRepairTips757]

Check for a vacuum leak or one of the intake hoses not clamped correctly

[@StitchDGlitch]

I did this a year ago and replaced the position sensor, but rough idle didn’t start until just a few weeks ago… I’ve done valve cover update.. new coils, wires and plugs recently which has greatly improved my mpg. I am now thinking fuel injectors need replacement, I’ve got over 180k on this thing.

[@StitchDGlitch]

It’s not the injectors. So maybe o2 sensors? I bought a scanner that gives live data readings, so before dumping money I’ll just check out the data.

[@BTKKILLER1]

You have a air coming in threw a loose or corked out house. Turn a cigar on and blow the smoke threw the master slave hose and look were the smoke is escaping from that's were your having air coming in from

[@matthewkaptena9512]

Ever find out what the issue was? I'm in the same boat, have already replaced all the same parts, and was about to buy fuel injectors.

Hi, my 2007 audi a4 b7 has very weak rev at idle. I stepped on the gas and the rpm just slowly goes up. Before it revs up nice and strong. Any help would be greatly appreciated. Thanks.
