My friend has a 2002 GT 5-Speed and full bolt-on’t on it. The car was running perfect and suddenly this problem appears? The car is dying and the acceleration is too heavy from idle to 5000 RPM range and then from 5000 to the rev-limiter is perfect.
We checked and replaced all the sensors like Cam position sensor, Crank position sensor TPS, Changed the coils, MAF and the spark plugs, cleaned the injectors, replaced the fuel pump, fuel filter rail to a new one.
The car gives feeling that the timing is retard up to 5000 RPM range and then return back to normal to the rev-limiter.
Here the car modifications:
Hooker LT, Hooker X-pipe, Borla cat-back, 4.10, BBK 75 TB, Trick Flow plenum, BBK U/P, March ram air system, K&N filter, Comp Cam XE262AH-13 and Diablo Tuner. 293 rwhp / 310 rwtq with tune.
Your help will be appreciating. Regards,
