Here is the deal
The car is a 2009 Corolla S manual transmission. The car started this issue two years ago, were it will rev up at an idle.
This only happens when it is colder outside, it needs to be below 30 degress. although it will do it once in a blue moon when it is hotter outside. If you drive it for a while it will not make a difference, but it will occur less. As you are driving and come to a stop, with the clutch in or out it will race up to 2000 rpms, or it will go up to 3500 rpms, it will drop down and rev back up and keep on doing it until you drive off. If you are in a drive thru it will do more so as you are getting off and on the clutch.
I have had the car to the dealer; the first one did not even try or care. The second dealer is working with us, but they say they can not get to reoccur, even though it does it as soon as we pick up the car. And we did get it to occur for them once, we are just not getting anywhere.
I used to work on car for a living a few years ago, but did not want to spend my money to fix the issue, but the car is now out of warranty.
Now I know the old motors had this issue, for intake manifold gaskets, and ECU.
I did have a recall done on the car for the brake failure… I’m wandering if the recall did not make this issue happen.
I feel this is a ECU failure, or it might be a coolant temp sensor, throttle body or wiring.
I wander if anyone has this issue before?
