Hello mate

Found your post

Right, based on the other electrical problems you were PM'ing me about before i'd say you've got some serious problems with the loom in this car.

One thing that does spring to mind is the alternator wont usually charge properly until the revs have gone up slightly, but it really shouldn't affect things like the rev counter as there should be more than enough juice in the battery. And as for coughing..... ???? i presume u mean it momentarily miss fires/bogs out?
