Any ideas on causes for lumpy idle?
The revs don't seem to move on idle, it sits at about 700rpm but u can feel the car shaking some times. It's not a constant shake, almost as if its misfiring once a second.
Some times it takes ages to start and sometimes when it starts the revs hang for a few seconds before it drops to idle speed (sounds horrible...)
I'm thinking cam shaft sensor?
It runs smooth as silk if I hold the revs at around 900rpm and never has an hesitation once driving, just feels and sounds horrible at idle.
