Engine Performance problem
1998 GMC Sierra V8 Four Wheel Drive Automatic 120000 miles
Hi, My truck starts fine. Sometimes has extended turn over. The problem is that as soon as I put it in gear it starts idling funny. If I give it gas it spits and sputters. If I don't touch the gas and let it drive at idle it clears up in about 10-15 seconds then runs fine. It only acts up again if I try to accelerate too hard (put it to the floor) then it almost backfires. Any info would be greatly appreciated.
have the same problem?
