typeR_Jag

Right guys, I have a 1999 sti type R jap import, got idling problems - how strange NOT!! - changed maf, o2 and ICV reset ECU etc etc. but still no joy. Checked for air leaks still no joy.

I am thinking now it could be related to the TPS, basically the car runs fine but everytime i come to stop the needle drops just above 0 then shoots back up to 600 ish rpm, when standing the idle is fine.

From what I can gather the TPS is on the manifold just below the ICV on my model of car is this correct ?

I have also read on here how to check the volts using a DVM, but I dont understand how to adjust the settings is it a coase of turning the unit itself clockwise or anti-clockwise or what? an idiot proof paragraph would be enough so that I can try adjusting/replacing.

So far no new fault codes or cel lights come on.

all help much appreciated

You can adjust the TPS by undoing the 2 screws and turning the unit in relation to the butterfly position.
