Engine Performance problem
1990 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 167000 miles
it runs for like 10 minutes then bogs out, it will idle fine and restarts every time but it bogs down completely? I have taken the catalytic converter off and it doesnt have a mass air flow sensor but a map sensor but I changed it also? I have also changed the fuel filter, crank sensor, and temp sensor and I have checked the fuel pump pressure and it says like 30 pound pressure so if u have any ideas would u please let me know! The weird think is the check engine light is not on at all so if u can help please let me know! Thanks alot!
have the same problem?
