Hello,
I recently had to face a short moment of fright, as my idle went down to 500 rpm in the middle of heavy traffic. But the engine went on smoothly. During the acceleration the rev counter moved rather sluggishly. It appeared to me, that the rev counter decided to reveal half of the current rpm over the whole rev range from now on. I didn't check it out, while revving the engine to its maximum potential.
As far as I remember, the transplantation of the 2.0l turbo engine into a 205 usually comes with this kind of problem, the rev counter operates improperly. Usually a kind of technical device or circuit is implanted in order to double the rev signal. Does anyone know, where this circuit is usually to be put? I don't know, where to start looking.
What do you think? Is there a chance, that my rev counter itself has got a mechanical or electronical problem?
Much thanks in advance,
Dandu
