93 Grand Prix Posted September 18, 2002 Report Share Posted September 18, 2002 I finally got my spark plugs replaced, with transmission fluid change, but my car still has the same problem. It has no acceleration in 4th gear. It stumbles like crazy. Shawn Lin says it could be a bad coil or fuel injector Can someone tell me how to check :?: Any info would be greatly appreciated. Please help a (POOR) college student out Thanks for anyone's help, and God bless! Quote Link to comment Share on other sites More sharing options...
