Out of the blue, I’ve got these two faults. I replaced the pedal sensor with a working one for test purposes, but that didn’t sort out the problem. The car is very difficult to start (feels like no cold start function), then runs at just over 1.000 rpm without responding to the accelerator.
What can I do, any tests you recommend? Might it be an electronic problem? How to diagnose that?
What I did before was changing all 4 lambda sensors, smoke tested the plenum (no leaks) and changed the oil. This should have no impact at all to the faults. No more faults are stored.
Car is a 2001 "S" 986
