2002 pontiac firhawk "mechanical question"?
I currently own a 02' pontiac firehawk. Current mods are long tube headers, underdrive pulleys, borla catylic converter, custom tune programmer, TNT nitrous system "setup to 100 shot." My current problem is when i accelerate light on the pedal it hesitates. A better description would be it lags a lil but only does it sometimes. The check engine light comes on, but doesnt blink. I was thinking that it could be the O2 sensors, but the guy who did my custom tune deleted my codes for that so it wouldnt pick it up. After driving it a day or two, the light went away and is now up again. I just had the fuel filter replaces 2 weeks ago and the computer retuned. It started when i was driving in the rain, but dont know if it was caused by that. I keep thinking maybe its my wires, but i looked and cant see a spark when it's dark out. I dont really want to take it to a dealership, due to they would charge me an arm and a leg just to tell me they have no idea...any ideas...would be great. thanks
i own a repair shop,and you can take it to auto zone,and let them scan it for you its fast and free,and will tell you if you have any bad sensors on it,that will cause this to happen,,that would be the best thing you could do for it,,then this way you,ll know at least what your dealing with,,good luck i hope this help,s.
