Thread: Idle issues after going to the dragstrip

How much tension should be in the cable?

Mine is kinda relaxed

check your tps settings and use that to set where the cable sits. you want the cable loose enough for it to have the tps in right spot when closed. and at the right spot at the tps full throttle spot, when pressing the pedal i.e. not from pulling the cable. and make sure the throttle body is clean.

I did that yesterday, once I unplug the TPS and the car is warm it won't die

Just did some tests thru Datascan, tried to make the idle relearn and it did nothing

Tried to mess with the IACV settings (0-100) in Active test and did NOTHING

Next step is check volts at the plugs and then replace the ECU

Replaced the ECU and did the same thing, starting to think my IACV is screwed

yeah i think so^^

I can just swap the AAC solenoid from a Lowport IACV right?

Running out of ideas

There's 0 volt at the brown end, the purple one is working like a charm and reads once I turn the A/C on, also idle like crap when I disconnect it

If you've had a few high rpm runs on boost,i would check the small spring inside your idle air control valve....

It's a N/A VE

Since the ECU sends (-) I can discard the posibility of the arnes, gotta check the (+) source that is missing

do you have a DVOM?

there is a fuse that controls that circuit i beleive its in the cabin. trace that wire and probe it to find out where the open is. the aac should read within 10 ohms, check that also
