Im currently scouring through my haynes manuel to try and find how I can locate and possibly name the sensor that controls the revs..
My car is a 306 xs S reg
The car runs fine apart from the revs dropping when they like. The dont over rev but bounce back from 750 revs to 1100 revs.. I cant find a cause for the revs dropping is there anyone with similar experiences.. It happens more when in traffic and idling etc..
