Wtf! alright heres my dillema. yesterday while driving my car it misfired. later on in the evening it stumbled again then quit. so this morning i went to carquest picked up a coil to see if it would run. i swapped coils and it fired right up.i was happy and headed home. tonight on my way to the pub it stumbled and quit again so i towed it home. now i dont know what it is. it seems when the car gets hot it quits. is the fuel pump fried or the optispark or the ICM. I need help ASAP
check the postive battery cable right near the ac compressor. Alomost the same thing happend too me on my 94 Z. the cable touched the clutch and it would hessitate and every now and then die, I took me two month too find the issue.
PS I replaced the coil first to.

if i let the car sit for an hour or so it fires uo and runs mint for 20mins the coughs and sputter at 4500 then to 3000 then 1500 then it quits the whole time it runs the fuel pressure is at 38psi then 42psi when the motors off. this is my daily driver and i need it back on the road. i dont know if i should buy an optispark or a msd 6al first to get it going
That would be cool. I kinda miss the carb'd 350 I had in my 83 Z28.
Are you running a 6al now? If so just take it out and see if it runs normal. I tried this when my car was running like garbage. I had a 6a, took it out, made no difference to the problem, reinstalled it after figuring out the inside of my opti was a rusted disc of garbage.

get a test light and check the voltage at each injector, wait till the car is warm (or at the temp where it has missed in the past week) if everything is firing, check the spark plugs, and plug wires. How many miles are on the opti? And have you done anything to your valve train, when i changed cams i didnt properly adjust my rockers and after a week one cam loose, took me a month to figure it out. Check maf, by having the car run and tap it w/ the butt of a hammer, if it stumbles bad maf. Keep posting and don't get fed up, these cars are a pita but you'll get it. let us know
