Hi,

I've recently rebuilt my engine and reinstalled it. It now won't idle properly in Neutral and Park (1500rpm) but returns down to 800rpm when in a gear.

I've disconnected the Idle control valve with no effect as too the breather system.

ANy ideas? I'm taking the car to a BMW specialist to diagnose what is going on, but would appreciate any suggestions that I can investigate before hand.

Cheers,

Martin

Sounds like a faulty idle control valve to me? I've had a few do that in the past.
