i have a 94 gsr stock gsr manifold and a few other upgrades ne ways the car bounce off idle all the time and i was told by a mechanic and this what i thought to but he told me to replace the iacv which i did and it didnt fix anything took back to the stealership had them hook it up to the ob2 scanner said i needed a new iacv HAH i just bought one from them 2 months ago ne ways it will sometimes stop bouncing if i have the A/C on but it will tach to 2k and hold there anyone know what else this could be. oh by the way theres like 190k+ miles on the car if that helps. any help would be great.
