Hi there,
at the moment I am on the track of my sporadic idling problem (plus 8 '93 CUX14). Sometimes the engine runs too fast at the traffic lights. Some days everything is ok.
I checked the electrics of the speed signal (many thanks to Mike (teknome) for sending me a circuit diagram!) Then I built an adapter that allows me to access the engine control unit with rovergauge.
Everything looks good, even the stepper motor can be controlled when it is removed.
I have come to the assumption that a sporadically failing mechanism of the stepper motor could be the cause.
After cleaning the sealing surface and a few drops of WD40 on the mechanics, the first test drive was successful. But how long does it last? I would like to swap the stepper motor.
Now I've read a lot about poor quality spare parts. Has anyone had a good experience with a particular supplier?
Greetings from the Sauerland (Germany)
