Yeah there's a sensor in there but I don't think it's very delicate so it's should be grand.

Did you reset the ECU after changing the throttle body? If not you could try that and it might fix it. Mine usually only idles like that until it's warm and then drops down.

It lets the ECU 'learn' to use the new throttle body or any other mods you've done. It'd be used to having the dodgy the TB and now that you've put in a new one it still thinks the old one is there and that might be why it's idling high.

I'd say your rear tyre pressures are too high.. However, if you rectify this, and don't tell the ECU, you may experience a slight knocking sound from the nearside upper suspension arm.
A quick fix is to remove the radio and wrap it in an oiley rag and put a match to it.
For 2001+ cars you need to remove the radio and the entire centre console, plus the rear centre armrest, and burn these all in one go.
The problem should go away within the next 100,000k miles.

Hope this helps.

just ajust the throttle position sensor on the side of the TB .
leave the car runnig and open the two screws slightly and rotate the sensor a little bit.

Ya, you are on the right track there ok.. I lost visual for a few minutes but all seems to be back on-line now.
My ECU has an over-boost conecter applied to the output board, and pin number nine relates to the source code for the mapping software.
If I remove this conecter will my overall power (bhp versus torque) increase by 10 bhp or should it stay the same?
The reason I ask this is because my mate has a Porsche and he reckons that it may be quicker than my car in a straight line.. I'm not so sure...
Thanks for your advice.

Impossible to get to those screws though, you'd need the car jacked as there facing the road and even than woud be hard to do with all the stuff in the way
