Not sure I am following your question.
The voltage regulator for the alternator on a GM product is built into the alternator. Not much of a chance the alternator could have too much voltage going in. Maybe coming out.

I just fixed my car, it was the spark plug wires leading to the wrong plugs, it runs like a champ now. Just did my first burn-out! :)

Flashout code 12 and 33. 1989 cavalier 2.8l v-6 black smoke, runs rough and stalls. Map sensor replaced, tps replaced, fuel pressure checked... all ok.


If you have never tuned the vehicle up you may want to start with that. especialy sparkplugs cap and rotor,wires. Sounds like the black smoke is unburned fuel or incorrect fuel/air mixture.

89 z24 stalls instantly when shifting out of park


Your lockup torque converter is bad I believe. When you shift from Park into any gear it will die.

1989 Z24, 2.8v6 intermittent stalling while driving. Sometimes will restart, but not go far, sometimes will not restart at all. Usually starts fine the next day, may run OK several days before acting up...


the pcm may have a cracked board, i had an 88 cavalier z24 with the same problem, replced the ecu and it ran fine, the problem is that the boards inside the pcm crack and lose connection, the next time it acts up open the glove box and try tapping on the pcm, if the car responds at all, the pcm is bad

it sounds to me that the sensor your talking about is the camshaft positioning sensor. It regulates how much fuel you get to your engine, so that is also why you have the fuel smell as well.

Have similar problem, seems to be too much pressure build up in the gas tank, when you loosen the gas cap, there is pressurized air comes out. If I leave the cap loose, the car runs fine

It sounds like you may have a broken exhaust valve spring, although, like you have found out problems like this can be very hard to diagnose, but anyone with a compression tester and couple other tools could find out if this is the case. Hope this gives you another idea where to look.
