MISSES WHEN I GIVE IT GAS AND ENGINE LIGHT IS ON

1999 Pontiac Grand Prix • 162,000 miles

I have replaced egnition module coil pack, cam sensor, crank shaft sensor, and last Ithe throttle position sensor. It misses bad when im driving and even misses when it idels and reving. Idk what it could be. The engine will stay. On for months at a time then suddenly go off and the car will run great. No misses or anything. Then it will come back on if u go to to pass someone and it will flash a gew. Times then start running like crap again. Can u help me or no.

Have codes been read for engine light being on? If yes what were they?

I havent been able to read any codes cause the thing where u hook a machine up wont let anything read it. Idk if theres a fuse blowed. To it or if the whole car is messed up. Im gonna try a map sensor today.

You can keep throwing parts at car and maybe fix or go to ASE Cert shop find out what is problem. Already spent plenty$$$ with no results
