Car just painted, Now having an engine issue

[Nevergrowup]

My car behaved like that after I had disconnected the battery for a while. The reason was the incredibly dirty throttle body. After the disconnect the car tries to «learn» and adjust to the environment, but it was not completely able to do that until I cleaned the throttle body.

I think that while the dirt slowly build up over a long time, the car adapts, but when I reset it with the battery disconnect it was «overwhelmed».

What year is your car? If it is an older model with a cable controlled throttle body it could be the idle control valve.

Well to add to the list of things to check, I suggest looking for a vacuum leak. I believe if you remove the oil cap while the motor is running and the idle doesn't change, then you have a leak. Unfortunately there's tons of places where it can be leaking from. Most of the time it's the oil fill tube or crossover tube going from the intake to the AOS.

+1 on cleaning the throttle body. Perhaps the body shop didn't do a good job masking up, and she's sucked dirt in.

Replace the air filter...clean the maf with that spray and the throttle body.
