383 LT1 PCM problem?
I have a 94 Z28 with 383 LT1 dyno tuned 400rwhp. a few months ago the car began acting up (spitting and sputtering, stalling ect..) it stalled and now i cannot make it run. after stying to start it it floods the cylinders with fuel causing it to vapor lock (wont turn over). i have pulled all the spark plugs rolled it over to remove the excees fuel, and replaced them. i tried again same result. pulled the plugs again and discovered that 5 of the 8 cylinders are getting washed right out. the other 3 are not getting fuel at all. I believe that my PCM went bad. Is the pcm the only thing that would control the injectors? Any help would be greatly appriciated

wow...that certainly seems crazy. I cant imagine the opti causing that but it wouldnt really surprise me either. If the pcm were told....false information, from the opti....then it could happen I guesss....and not be the pcm.
The easy thing to do is copy your tune...(if its not already) swap a known good pcm...and upload your tune. Way easier then swapping plugs.
