Idle valve?
Looking for this chappie

Life is not a journey to the grave with the intention of arriving safely in one pretty and well-preserved piece...but to skid in broadside, thoroughly used up, worn out, and defiantly shouting "wow, what a ride."

Re: Idle valve?
Top 1. The one that look like a long nut with plug at the end. Dus it control engine idle? Or idle up when aircon switched on?

Re: Idle valve?
If I unplug it nuting happens with the idle even if I put on aircon. Cant get the idle down. It idles a 1500rpm.

Make sure you don't have a vacuum leak. One of the small pipes by the intake mani.

Re: Idle valve?
Have you tried adjusting the idle at the screw?

Re: Idle valve?
Then I'd do what rat suggested, start looking for air leaks. Or maybe the "choke" / cold start auxiliary air valve is stuck open?

Re: Idle valve?
I removed all the sensors yestrday and cleaned them out,replaced all the vac lines aswell. Idle stil high. Tried to feel around intake for any leaks. Could it be intake gasket?
