So heres what I've got going on. When my car is between outside temp and 160*F it won't idle properly until it comes to a complete stop. Once the car has warmed up, when going into neutral it idles just fine while still rolling and coming to a stop. One thing my idle issues has in common is wether my car is warm or cold, whenever the AC or Heater are on, it WILL NOT idle properly.

By not idle properly I mean stumbles and falls to roughly 500ish and then idle hunts from there until I come to a complete stop, then it snaps and holds to there i've got my idle set. I'm checking on the HPT forum as well to see if theres something I can dig up but I'd also like to hear from you guys. Is there a table somewhere that needs adjusting inside my tune?

Any help is appreciated!

Did this problem coincide with adjusting your tune? If not, I doubt it's a tune issue. When's the last time you cleaned out the throttle body?

So this problem didn't come with any tune adjustment, it started happening about 3 weeks ago when it rained for the first time in months where I live. Since the new moisture in the air, it hasn't acted properly since. I cleaned the throttle body, catch can and all conjoining rubbers hoses yesterday, and still nothing. There is still quite a bit of moisture present in the area even after being so long ago that it rained.

Ah. I'm no expert on tunes so I won't comment on how moisture or temperature might affect it. I'm having an idle issue right now so I though I'd chime in and give my $0.02 and watch for possible solutions for mine too.

How bad did it rain? Honestly, I'd buy a can of MAF cleaner and go to town. You aren't running an L61 so this shouldn't be your problem, but just for the hell of it: Does your L61 (RPM and AFR) idle weird when you turn on your A/C? Step inside.
