Hiya chaps, after cleaning my throttle bodies out, I reset the ECU and the revs idled about 1300 rpm. I've done a little over 250 miles now and it's not particularly altered. So, I tried setting the TPS to .42 Volts, with engine running disconnected the IAA connector and adjusted the idle, got it to 1000rpm with no more adjustment on the screw. Re-connected the IAA plug made no difference at all. Apparently from the procedure I should hear the solenoid click and the revs rise slightly but no. Checked for voltage at the IAA on idling & I got 12V which is correct. Tried cleaning the connector but no joy. I'm lost now as to what to do. So maybe someone could point me in the right direction. Could it be I need a replacement IAA unit (how much are they gonna be???????).

CheerZZZZZ Jonny.

 

P.s sorry for the essay just trying to explain the fault.

Seems like you're getting to much air in.

Could be:

- a stuck/dirty air regulator

- a stuck/dirty AAC-valve in the IAA unit

- vacuum leak

 

You can clean both the air regulator and the IAA unit.

Check out the tech section on my home page for details.
