Roger! Cheers Rosssub, you are a fount of knowledge about these things, and I have read almost all of your threads about TT Subies.

So I've got the knock sensor out... What an absolute arse that is without taking 3/4 of the stuff off the top of the engine. Might be interesting getting the new one back on.

Cool, will do that with teh new one. The old one is well broken as the plastic bit on the end is completely separated from the actuator, and the actuator doesn't move at all, which would explain the CEL.

When I was attempting to move it, by pushing it in I might add, the plastic bit that seals in the throttle body came off in my hand, and the spring flew out into the engine! Managed to find the spring luckily,but now it really doesnt work! The car wont idle steadily, and occasionally will rev to 3000+ for no reason. Luckily I still have my old car as the GTB is a bit undriveable like that... And apparently there are 2 knock sensors listed for that engine, and I have no idea which one mine is, so tonights job is find the damn thing so I can see which connector it has!

Cheers! PM sent!

So I pulled the Idle control valve tonight to clean it a bit, and it exploded into several bits halfway through cleaning, which was slightly awkward. Has this happened to anyone else? Also does anyone in CHCH have a spare one? as the car doesn't run very well without it, which is not very surprising... Or how much a new one is likely to be?
