Thanks, I never noticed that before :hides:
:faint:

On the original topic, do this:

1. THOROUGHLY clean your IAC. by this I mean remove the throttle body from the car, remove the IAC from the throttle body and thoroughly clean out the IAC. I used q-tips, solvent and some small picks to move the barrel valve around. The barrel valve should move freely and snap back into place if you move it. Spraying cleaner down into the IAC port will not do this.

2. Get the car up to full operating temperature and shut the car off.

3. Change the values in your INJ vs. WaterT and INJ vs. AirT to the ones in the following map:

3. Read in your map, save it to the computer, then do the function that says "Initialize Power FC". You will need to cycle the key off and on. Then reload the map and start up the car. Let it idle for about 30 minutes that way.

4. During this time, turn O2 feedback off and mess with the active cells in the Base Map (with auto update turned on) to dial in your idle AFR. This is of course assuming you have a wideband.

5. Check your Idle A/E and Idle A/C values against your F/C A/E and F/C A/C values. if your car is surging at idle, it might be because your F/C (fuel cut recovery) values are too close to your idle values. Bring those up by 100 rpm at a time until the surging problem goes away.

oki so.. even if i do those its not gonna mess up the tuning set up?
im juss afraid of messing up some tuning set up since i have NO experience on any engine management system.. and dont even have a labtop..
btw i dont have the wideband 02 yet..
You have a Datalogit but no laptop? :wtf:

So yeah you're kind of screwed. And don't worry about messing up the tuning, I was only talking about a few cells at idle.
