Engine Failsafe Program-Idle Valve-low response from Accelarator
I need your urgent help please, I recently changed MAF and Cam Sensors with Fuel Pump .... and now my car is giving Error Code for Idle Control Valve ..... I tried changing that also but still error is same .... Moreover, after driving a mile, getting message of Engine Fail Safe Prog on Dash and instantly when I get this message the response from accelrator padel goes low ..... I mean Even I push the pedal to full, the car accelarates very very slow .... can anybody tell me what could be the reason ... Car is with my mechanic and he just call me to say he wants to repair its catalytic converters ...... i tried finding out on previous forums also but couldn't find anything .... could you guyz explain me in layman language please as I am new to BMW world ....
Thanks alot in advance
