cruzin again
I have had an ongoing odyssey with the ignition system on my 93 coupe. 6 plus years, at least 5 optis, it would run for 200 miles or so, the quit. The last time I varied the process by installing a Delphi distributor, instead of GM rebuilt, and had the ECM rebuilt. Lasted 200 miles. Finally after desperation I carried it to the Chevrolet dealership. What they did, they shot gunned it with a new coil and ICM. I had tried this already. I think it was the ICM. I had used one from Advance but I believe it to be a POS.
It now has a skip from sitting up for a year, gas jelled, clogged the injectors. Chevy folks say run a couple of tanks of gas thru it. I;m on my 2nd, but it still has a skip. This is most pronounced when decelerating. I shift into neutral, because it may break a motor mount. Running Marvel Mystery oil in my gas. skip is some better, but still there.
I highly recommend if you are changing a opti, go ahead and change the ICM. It's been posted here many times before.
I hope after driving around some, things will be normal again.
