W reg (2000) pug 206 xs Sometimes, just sometimes, when I drop the clutch, the revs dip so low the engine cuts out, the dash lights come on and the door locks pop up. This could happen 3 or 4 times on a 3 mile journey then not again for 2 months. It seems totally random. Sometimes the revs do dip very low but then jump back up, then down a bit then back up, what I call the yoyo effect. As long as it doesnt stall this bit doesnt bother me. Does anyone have a clue what could cause these stalls? Thanks Lee
