Idle speed
« on: 14 February 2011, 10:16:49 »
Hi can anyone tell me what the idle speed is for 2.2.
I have just had head gasket done and now it seems too low. Its idling when upto temp at about 600 but seems a bit viby. If using throttle to take it to 7-750 its fine.
When starting from cold its fine and when running fine.
Could having the head skimmed be a cause, and is there a way to adjust the idle speed. The throttle body and pipes have been cleaned.
Cheers Glyn

600 is fine with the air-con off, which it will be in this weather

As Rob says controled by the ECU but I think it can be adjusted with a Tech 2 if really needed.

Idle cannot be adjusted, its ECU controlled as Rob says. If its lumpy/uneven, i'd be checking for any air leaks, oil in the plugs and the age of the plugs for basics. But if you've had work done, take it back, as its not right  :y

Thanks for replys.
It actually idles perfectly.Drives perfect as well.
Its just at idle, there is a vibration which you can feel and hear and goes away when you add a few revs.

Getting the ECU to compensate/mask another fault will only end in tears...  ...that said, I'd expect tickover of a 4 pot to be a dead steady 700-725rpm


On that lump, a full breather and TB clean can do wonders.

Solved
It was the exhaust. A rubber mount had gone and left it too close to the body.
