It just started this morning when I started my car the idle shoots up to 2K and won't drop any lower, it didn't do this the last time I started the car, I tried turning it off and starting it again and it did the same thing, any thoughts anyone?

 

Its the AWS..

 

AWS?, and if so whats the fix because this just started this morning it has not done this before. Normally the car jumps up to 1,500 and then idels back down to 850, but this morning it shot up to 2K and stayed there

 

did you start the car in gear? is it stock, whats done to the car.

I doubt its the AWS if he's never experienced this before.. unless you've always started the car in gear. If your car is stock it has the AWS (Accelerated Warm-up System) which allows the cats to fire off and get cold start emissions down.

However if you start the car in gear.. it "disables" the AWS somewhat.

If this is your case.. then its solved.. if not.. Look for a Vacuum leak.. listen for any hissing in the engine bay.

 

make sure the cruise controll is not binding

 

I have always started the car out of gear and the car is not stock, my mods are in my sig.

 

so are you non-seq or still seq.. i'd check for a vacuum leak.. pretty damn sure.

 

I had the same problem a little while ago, it turned out to be a intake gasket when the new motor was installed the jerks used a paper gasket for some unknown reason. had the gasket replace and now idles fine

 

It depends. The aws system is not always the same.
Depends on the temps and the tension on the throttle cable.

 

i think its hte isc, same exact thing happend to me one day, i just unplugged it adn it ran better then ever also check the throttle cable tightness.


hmmm otherh thigns you might wanan try disconnecting would be the...

dashpot
ISC
AWS
Wax rod assembly
fast idle screw
the airpump solenoid


good luck in anycase

 

oh yeah, to find air leak, just spray starter fluid aroudn the suspected leaks and if your idle climbs, bingo

just watch out for flammage if you spray near your turbos/exhuast, its very flammable

 

well I am still stumped, I did check the throttle cable, seems fine to me, I listened for vac leakes but didn't spray anything yet. It idles solid at 2K it's not searching or anything, and once the car is warm it drops back down to normal idle, I am pretty sure it's the AWS system but I don't know why it would suddenly start doing this, how do I go about disconnecting the AWS I'd like to see if that works

 

If it had a vacuum leak, wouldn't the idle be affected regardless of water temperature?

Keep in mind his problem only occurs on cold starts and as he said, the idle drops to normal level when warm.

 

Ok it can't be the AWS because it's disabled from the PFC, how do I check the air pump soledoid? I am hesitant to think it could be a blown vacume line because I had the silicone vacume hose job done about 5K miles ago with zip ties on pretty much all of them. But nothing is impossible. Any more advice would be greatly appreciated.

You are correct sir. Did anybody read his mods before they started saying AWS! AWS!
