I have been having consistent issues with the TB. It has had the factory wire extension. Situation is as follows: Steady driving car is fine but I do get several bucks and sputters while accelerating (probably misfires) On take offs from stop signs or red lights the car will violently buck unless you are careful with the gas pedal, but ultimately 8 times out of ten will result in EPC light coming on and now you're in limp mode.
Cons: car violently buck, EPC light
Vehicle:
Volkswagen
