hey i have an eb xr8 and the motor runs ok but it has a slight knock on idle and when in park and you give it a good rev it lets off a little backfire through the throttle body but then revs up fine this is very annoying as it is the only problem i have left to get my r.w.c so ican get it regersted.

All cylinders firing? No dodgy plugs or leads breaking down under load?

if it has a slight knock you could have a bigend or crank problem
