I have a problem with my car. its a 1.2 16v 2001. It will drive fine for a while but then a light comes on (it has a coil underneath it) and it sometimes revs on its own when sitting at lights waiting to pull away and quite often cuts out. Has anyone else experienced this problem and if so what will stop it? I've been told its definately the MAP sensor but i just wanted some first hand advice. Thank you!
