Hi, I have a w202 v6 2400. it has thrown up a code of p 1580 which says that the electronic accelerator /cruise control/ idle speed controller is the fault, Which makes sense as the tick over is all over the place and sometimes looses all power. Hunts and revs between 2000-3500 all on its own and accelerates away with no input from me, making me nervous. My question is where do I look for the offender?? tia
