Having problems with your Pontiac Firebird ?
I think my optispark is going out but not for sure. The car will start up but will not allow WOT it will cut out or die then is hard to start back. The service engine light will stay on until it sets for awhile. But is crazy thats making me second guess myself about the optispark. After getting the car to start and stay running the car will let me do WOT but it is slower getting to top speed and my exhaust smell like rotten eggs.
That rotten egg smell is unburnt fuel in the exhaust. I am no expert in ignition systems but i have heard that optispark systems aren't very hardy. Try replacing the coils, wires, and plugs. If that doesn't work its time for a new distributor.
