I have no clue what it could be this time. i've had the AIV out for about 5 months now and its happening all over again. it'll struggle up and down with the idle and when i take it outta gear it'll stall. its wierd b\c the car was running fine, then i parked and turned the car off for about 10 minutes then when i started it back up the idle problems that i was suffering from a few months back started up again. any ideas?

 

increase the idle speed call it a day. my old fastback would stall out if it dropped below 1000rpm or so...Idled at 1500-2000. But ran great.

 

check VAC and MAF.
