I have a 94 Camaro and it recently out of the blue started stumbling under acceleration. I didn't drive it for about 4 days when I put new front shocks, rotors and pads on, then I changed the oil because it was that time and took it for a drive and during that drive it started. I know the shocks, rotors/pads, or oil wouldn't be the cause. I took it to a place and they told me it was my spark plug wires and plugs but I put new Accel wires and AC Delco Platinum plugs on about 3 months ago. Also at that time I added new Accel Coils. The Haynes manual I have says if it stumbles its from the timing being wrong or dirty/clogged injectors or low fuel pressure. I have put fuel system cleaner in it before this happened so it shouldn't be the injectors. The timing is controlled by the computer since it is a DIS, so is my computer bad or am I missing something?

Re: Possible Computer Problem???
If you are sure your spark plugs and wires are good, check your coils and ICM, when I took my ICM and 3 coils into autozone, they all tested fine. I bought a new ICM and installed that with my old coils and it solved the problem. Came with a lifetime warranty, too, so I'm set for a while.

I replaced my spark plugs 3 months ago but I will pull them out and get new ones and see if it runs better and if it does I'll take the old ones back.

If there only 3 months old you dont have to go buy new ones...Just check them to makes sure there not cracked/damaged and make sure there tight.
Since there 3 months old and the problem just started i'd check that there all tight first...but dont buy new ones unless there damaged, waste of money

by ssms5411Went ahead and moved my starter wire from the back, to the front again since it had no effect on my drain on the battery. Also made me nervous driving...1 week ago
