hi,fellas!!!!i need some help,my 94 gt is running ruff!But the funny thing about this deal is,it doesn't do it all the time.The car shakes real bad almost like a bad miss,THE exhaust shakes and vibrates the hole car i have a scroll computer and every thing comes back fine.I was thinking it might be a injector going bad?It might run fine for 2 days and the next day its back again.I'm hoping someone else had this problem.

Does it get any better when the car is warm? What about when you first start it???

Start with the simple things. Make sure all 8 plugs are getting spark, make sure timing is right and dizzy is tight, check cap/rotor, main battery connections and main ground, clean your MAF & clean/index your IAT. Check fuel pressure and vacuum at idle. Then yank all 8 plugs and note which cylinder it came out of, and what the plug looked like (i.e. dirt brown, black, black and oily, dirt brown with some white, white, etc)
