subGSR Posted January 10, 2005 Share Posted January 10, 2005 Merry Xmas and a happy new year to everyone. Well we have a we prob with the gsr. It was going magic then a reaccuring problem came back. It fixed itself last time but has us stumped as to what it is. The car has a slight missfire or backfire and surges at low revs. And it has a pre-ignition problem when you turn it off. We think it is the following combined (timing,fuel mixture,or a worn distributor,)Does anyone have any other ideas as to what it might be.

carfreak85 Posted January 11, 2005 Share Posted January 11, 2005 Maybe excessive carbon buildup in the cylinders or other hot spots? Quote Link to comment Share on other sites More sharing options...
