Sent to Car Experts August 05, 2006 4:07 a.m.

i have a 1994 pontiac grand am that has a brand new remanufactured engine and transmission, but it misfires when it idles, it goes to a really high rpm then it goes really low and sputters. sometimes it wants to accelerate on its own and most of the time it stays at speed even up hills when i dont have my foot on the accelerator. i have replaced the spark plugs, coil paks, ecm, tps sensor, idle air control valve, fuel injector o-rings,and one fuel injector. if someone can tell me what is wrong it would be greatly appreciated. thanks. Brandon C.
