Ight well my car is having a hard time idling now like when i start it it'll idle about 1500 and ill let it warm up for a bit and revving it a for a little while and it'll drop down to 900. Then ill take it for a drive around the block and when ever I come to a stop it'll feel likes its about to stall out. So far I've replaced the spark plugs check the grounds and replaced the iacv.anyone have any more suggestions before i had it over to the shop??
