too many hoses Very Happy . When you said you "uncover the port it idle at 3k" - does that mean that you took the coolant lines off and left it open? I'm hoping somebody else can help you cause I'm struggling Confused Maybe you need a new Auxillary air valve...

please read this from start to finish:

An extract from here says that when it's faulty idle speed usually increases so maybe this isn't the case or yours is a different case of same prob. But if you've got 5 min read the link above so you don't start tearing things off and jumping to conclusions.

Quote:

This feedback indicates that the Auxiliary Air Valve (AAV) is perhaps the biggest culprit for both hot and cold idle. This makes sense - it is a waxstat device - and the wax capsules do leak eventually - so the valve no longer opens and shuts when it should. The principle is similar to the thermostat in the cooling water system.. (The AAV is a bypass air channel around the throttle plate meant to lift cold idle rpm and be shut when hot.)

Given the age and mileage of all our cars this is quite plausible - loss of wax means it could be more open than it should be - hot or cold. This then means that both hot and cold idle revs are affected - upwards.
