You can also try the idle relearn procedure. Just look up toyota idle relearn and follow the steps. Spray some soap and water to see if any vacuum leaks.
I also have a 2013 corolla s been doing that same for awhile now changed throttle body plugs wires battery alternator and still have the problem going to try this thanks man
It is definitely something very common with this select group of years. A lot of people seem to have the same issue and haven't been able to figure it out. Let me know if it helps you. It helped mine for roughly 2 weeks and then out of the blue it started up again.
You need to clean your throttle body and also clean your fuel injectors throw a bottle of Chevron cleaner. The pcv won't fix this issue, but it is part of the Meintenance to change it. I have a 2015 Corolla
I have the same issue with 2013 Corolla, gonna try changing the PCV, and while at it change the intake gasket and PCV valve tube. Will update here once I'm done.
I would start by replacing the air filter which some people don’t even know what the car has it 😂 than it can be a lot of other things causing instability 😂
I have an issue with my toyota corolla 2013 LE and I replaced my airbox for a p0101 code and temporarily went away for about 300+ miles then came back. I was considering replacing the PCV valve and intake gasket but I can't find the problem. I get a too lean every once in a while.
I just finished mine. Unbelievable they expect us to change this out every 30k miles. I got down to that last nut on removal and (of course) it dropped out of the socket down into the abyss. I spent 90 minutes doing the job..but almost 2 hours finding the nut's hiding place. On earlier models, they used to have the PCV valve right on top of the engine. It was super easy to change out. Not sure why they did it this way..very frustrating and just really bad engineering.
Whatever engineer that decided to put the PCV valve in that location should get the idiot of the year award. My Tacoma takes about 10 minutes to change the PCV valve on.
Say it louder for those in the back! The headlight housing on this model of corolla are a pain to fix as well because you have to remove the bumper to get to them. Very silly design.
it gets worse i tried to do one on my 2arfe and i couldnt access it because its behind the intake too except its on the back of the engine. I said nope ill jusk keep adding oil
@@bossadamsgarage This fix also rarely does anything unfortunately. I still have a intermittent stumble and an idle that likes to hover around 800RPM. I recommend people look at their valve stems and injector ports while you have the intake removed. Mine were filthy. Why??? Who knows!
Also…do you also experience this shudder if you… 1. Either reverse or drive forward with your steering turned the full way? 2. Roll all 4 of your windows down and hold or roll 2 back up and hold??
@@bossadamsgarage have you ever had the ac recharged or had the compressor replaced? My cars got a grind that I haven’t noticed much anymore now that I start the car with the AC OFF. I haven’t recharged yet but air is weak. Might replace the compressor and look into upgrading cooling system parts along with coolant flush
I haven't replaced the compressor on this vehicle. I have only charged the system once before. Other than this studder problem, the car runs great with no issues.
No update yet. This is probably the trickiest issue I've ever come across in all the vehicles I've owned. Others are looking into the situation as well. I'll be uploading as soon as I figure out this issue. Seems to be very common in this year model Corolla.
The lower bolt is a lil bit tricky to put back in..I ended up braking the water outlet to the radiator hose 😅😂.. so it was a learning experience don’t lean on it cus it’s plastic
Try spraying some carb cleaner around the intake while it's idling. If the rpms go up and down the intake gasket is leaking. You probably shoud have changed it with the PCV valve. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NrT-FruVKxI.htmlsi=m6IiASnEo7-PR2vr
@@keithbaumgardner1603 I've got a few more things I'm going to try to sort out the problem but I've replaced every common part that could be the culprit to no avail.
@@bossadamsgarage do you think it's accessible by removing the starter? I'm just trying to find a quicker way lol. also, have you tried an idle relearn?
I haven’t done this yet. I was looking on Google images to see where PCV was and stumbled on your video. (Very good video btw) (Also my first time on your channel so not sure if other videos mention how many miles are on your car. + my $.02 mentioning engine code name might help someone narrow down if the video is for them. I have 2010 so I think we both have 2ZR-xx??? Also very interested to know what items are on your course of action list next. Will be subscribing and following. 🦾🦾
I appreciate you checking out the channel! I had the codes ran on this car but nothing popped up, which is why I'm so puzzled at this. My car is a 2011 with 160k miles, so it's not even a high mileage vehicle.
