View Full Version : Idle problem - again !

Hi guys
Had the throttle module replaced about 5k miles ago, however the idle has become inconsistant again :sinner:
It's ok after a hard run (must be due to moving the throttle plate WOT) but crawling around and after parking manouveurs (spelling?!) the idle will hunt +/- 200 rpm.
Can I clean this out myself with a little hassle ? Can I idle the car without the boost hosing attached (so I can spray cleaner in) ?
Thanks
Chris

Thanks for the input :p
To try and cure the idle, I sprayed in some Intake Cleaner through the aperture where a sensor usually sits, looks like a pressure sensor, at idle (this is on the plastic pipe that connects to the throttle housing after intercooler piping).
This made the idle solid again :)
Took it out for a run and everything was good - however, I let it sit for a few minutes to let the turbo cool down, turned it off, back on again and once again the idle hunts :(
Does anyone know what I have to clean inside the throttle housing ? Or do I once again have to go back to the specialist ?
Thanks
Chris

Right, I took it one step further.
I removed the intake pipe and cleaned the inside, as best I could, the butterfly :

Also, can anyone identify what hould be on the end of the circled outlet ?!

I'm thinking it may of had a rubber cover on it ? But the recent boosting to 1.2bar all the time may have blown it off ?!
Thanks

Circled outlet is meant to be blanked off.
