Olds88Cutlass Posted September 27, 2007 Report Share Posted September 27, 2007 ok i'll try to explain this as best I can. the car always starts right away, no hard cranking or anything. it starts up i put it in gear and the rpms almost go down to zero, the car shakes and the headlights, DIS, dash etc. dim. this happens for about 5 seconds and then it is fine. it seems to happen the worst when it is put in reverse. about 50% of the time the car just shuts off. when idling when it is warmed up or cold the rpms are betweem 400 and 800. it jumps up and down very bad and the car almost stalls. there seems to be a miss noticeable in the exhaust. the plug wires are new AC Delco. does this sound like a fuel or spark problem?
