vs v6 constant high idle issue

[Wozza]

manual says
unplug the connector and check the ohms across pins A and B then C and D each check should indicate 40 to 80 ohms if not replace
or use a scan tool/aldl cable

there should be slack in the cable at the TB not much 1 to 2mm

Pretty sure theres more to the procedure of setting the IAC. Theres a measurement you need to set the pintle at before you re-install it.

To reset the IAC, pull the engine fuse for a few minutes then reinstall, turn key to on and leave it for a few seconds, it will step all the way out and back in, then your done, this just sets the travel range of the pin.

If you want to check its working, pull it out, hold it together to stop it flying apart and get someone to turn the key to on, just hold it tight and it'l suck itself back in. Then repeat again with it back in the car so it can step in and out again.

The TPS requires no calibration, it will reset back to 0% at every key on, unless the voltage is to high.

If it was converted to T5 id be checking the memcal tune and ECU, most are not done properly causing the idle issues.

I pulled the TB off the other night gave it a clean and put it back together and now it rev's even higher.. I dunno what to do? I'll give resetting the IAC a go and let you know how I go!

Have you checked correct operation of the tps?

ALDL cable would be handy

I had similar issues to this, even after replacing TPS & IAC... The positive terminal on my battery was a bit loose, so tightening that up helped stop the revs fluctuations but the revs where still higher than nornal.
Turns out I had an air leak, there's a hose that connects under the butterfly on the throttle body. Mine had come out. Plugged it back in she's all good again.
