turning with a screwdriver for that reason.
New valve was $1300 nzd -ouch.
See if you can borrow one from a forum member to try on your car.

I don't think the new TPS will change your idle. You have a vacuum leak somewhere or it is the ICV. I would also check the ICV and throttle body gasket for damage.

as for the ICV, i dont get ANY idle control codes (I did for a day or two when i removed it and then replaced it...but that was before i had the TB/WP changed). I would like to try replacing the fuel filter as well as hunt for a vac leak (where do i start with those two?). IF either of those dont pan out (as they are both relatively easy to perform) then i will move on to ICV (damn nick *shakes fist in air) and then ultimately move to the prediction of a bent connecting rod on one of the cylinders. Please help in directing me to Fuel Filter and Vac test. thanks all.

The compression test is the best way to gauge overall engine health short of dissasembly.<ul><li><a href="http://www.robsaudiworld.com/compression.htm">Rob Andrews Compression Test FAQ</a></li></ul>
