I did post earlier but have more info on problem.
When I start the car it goes and sits at 4000rpm. I have cleaned out idle valve and throttle body etc. I have sprayed carb cleaner at the right hand side of the inlet manifold and the enging speed rises higher. The manifold is tight etc. Wondered if there was anything i could try. I was going to take the manifold off for a look but not sure whats involved.

Looked at all the pipes etc seem ok. There is a small pump like thig under the throttle body with a pipe going to the inlet manifold but dont know how to test.

Any help would be great thanks.
