My dad just moved my car, it wouldnt hold revs in neutral and kept dropping until it would stall. It did this 3times then it held the revs at 500rpm and sounded rough as.
Also the other day in the rain, when i put my foot on the brake it would illuminate the fog light light on the dash (if that makes sense) it wasnt fully lit but became visible, the car also started to drop revs. But was fine once i got going.
Any idea what this is?
