What could be causing the attached faults simultaneously? I parked the car last night - this morning it would not start. I checked and cleaned (contact spray) the DME connectors to no avail. In the past, I had a few occasions when the throttle would "stick" causing the car to idle at around 2500 rpm. Moving the DME connectors around would solve it (I assumed a bad contact on one of the signal cables). I have also checked all the fuses and the plug to the throttle body. The live values on Durametric do not change, no matter how I press the gas pedal. Normally, they will vary - e.g., "Pedal Value" going from around 0%, to 100%. Now, Pedal Value is stuck at 30%. Of note, but I don't believe it is relevant: The engine is an M97.21, the car has been running fine with it since 2010 (I reprogrammed the original DME myself). Any suggestions on how to approach this would be greatly appreciated. I am at a loss since the faults suggest a problem on both ends (pedal and throttle plate). I tried my best to ensure good contact for the wires plugging into the DME - I even removed each of the two "sections" that slide into the safety clip and checked that each wire is pushed all the way forward and locked. I am assuming it is extremely unlikely that the DME itself can go bad only in the circuitry involving the e-gas? EDIT (per the suggestion of JFP below): The car is a 2003 986 s. No modifications to the wiring harness, with the exception of an extension to control the M97.21 engine's two-stage valve lift.
