01 GT
Long tube BBK headers
Full length CAI
A few months after purchasing this car it gradually started to lose power. Started stumbling and misfiring before 3k and then would go away once WOT. At idle would run horrible rough, and poped and stutterers. When accelerating car would jerk and miss.
Ran codes and came out with a bad MASS air flow. So I replaced the sensor and replaced all plugs. And tightend up my collectors found they were leaking. Car ran amazing, better then before. Then about a week later check engine light came back on, codes thrown where exhaust O2 codes. Then a day later it is now running even worse then when I replaced the mass air sensor.
Can bad O2 cause it to run this rough? Or is it more likely my mass air sensor harness?
