I wonder if anyone can help with this little problem. Saab 95 2.3T se. went into limp home mode,error code says throttle return spring. replaced the whole housing. still has same problem. It has a bsr stage 1 and a td04 turbo. also getting some back pressure on the throttle pedal occasionally. i use a torque app on my phone to clear the error codes but this has to be done constantly. anyone got even a clue as to what is still causing the fault. coded 1260 and 1251. any help greatly appreciated.
