1999 3.2 TL engine idling up and down
My girlfriend has a 1999 Acura 3.2 TL that wasn't run for about a month or so. Last week, when she started it up, it began idling up and down between 1000-2000 RPM. I checked this forum and it seems it could be one of these things:
1. Low coolant levels
2. Vacuum leak
3. Clogged IACV
4. Bad FITV
I brought it to the local garage and it was diagnosed as having a bad idle air control motor. Is this the same as the IACV? Or something different?

I use seafoam every 30k miles (every time I change my NGK V's) and this is what mine looked like when I performed the surgery: https://www.honda-acura.net/forums/s...GR+clean+J30A1
Yikes.

get carb cleaner and clean the egr passages and take the valve cover of and clean the clooged carbon areas and change the gaskets on trottle body and egr because eventually your check engine light will come on for egr issues.
