91CuttyConv Posted November 22, 2002 Report Share Posted November 22, 2002 Hi all, I have a 1991 Cutlass Supreme Convertible with the 3.1. I am having a few small problems with engine. When accelertaing at times it seems to hesitate/miss while accelertating and then its fine after i even out the speed, it feels as if i were pumping the gas pedal slightly however I am not. Also, in reverse only the idle is a bit unstable, it never stalls but sometimes sounds like it wants to. I bought the car in August with 59,000 miles and the owener said it just got new plugs, could the plugs be bad/incorrect? would this cause these symptoms?

cstyle73 Posted November 22, 2002 Report Share Posted November 22, 2002 Check your plug wires. Mine was doing the same thing and new wires fixed my problem, Quote Link to comment Share on other sites More sharing options...
91CuttyConv Posted November 23, 2002 Author Report Share Posted November 23, 2002 Thanks for the reply, i will check that out as soon as possible, I am guessing the orginal wires are still on there. Thanks Again, Jason Quote Link to comment Share on other sites More sharing options...
gpse3200 Posted November 26, 2002 Report Share Posted November 26, 2002 Yeah it might be the wires, or the IGN module/coil(s). If changing the wires doesn't work, go tot he junkyard and buy another modulewith coils say from a 3100, swap the the rear mouning plate and install.
