That is one very long sentence.
PS: Can't time a 96 with a light.
PS2: Don't listen to the experts behind the counter at O'reillys.
PS3: Check for codes with a code reader at O'reillys.
PS4: Report the codes here.

I think Accel opti's are junk. I had one that lasted 15 minutes then wouldn't run at all. Since it was under warranty, I tried a second one. After about 500 miles, the second one started acting up.. if the engine was above about 5000rpm, it would misfire and cut out. And when that was happening, the tach would jump around. So the second one was junk too. So now I have an AIP opti. so far its been perfect

Optis always scared me away from the 91-96 C4s. I had a 89 for a while and I liked the "spin the distributor" simplicity.

Suspect you mean 92-96 C4s.

“oh ya while installed the alternator the plug got smashed and it arced out“ I suggest you disconnect the battery before doing any such engine work.

Yet another first post where the OP never comes back to see if anyone answers the question. Dan
