Engine Performance problem
2000 Pontiac Grand Prix V8 Front Wheel Drive Automatic 150, 00 miles
I have put a new computer system in this car because I was told there were a few bad sensors. My car seems to be getting worse every day and it quits going down the espressway but then starts right back up usually. There are several times in a week that it wont start and when it does start it seems as if it wants to chug when going up a hill or even just stepping on the gas. There has been a new air flow mass sensor put on also and when unplugged, the car still runs the same. I have put hundreds into this car and now have been told that there is no way my car needed a new computer system by several mechanics. I am being taken for a ride and Im getting upset. Do you have any clue what this could be? Someone siad posisbly a fuel pump but why would it just run crappy instead of just simply quitting, its been doing this for several weeks.
have the same problem?
