    Fault code 1d

    I've had this code and check engine on ever since the motronic swap. 1.0 -> 1.3.

    Anyone know why it would be on, and if it would cause any ill effects? IIRC it has something to do with vehicle speed. I dont have the check engine light hooked up, but I check it every now and then with the Peak reader.
