Here is a more recent one. Do not just write it to your car. Use the compare ferature and see what needs changing.

pm if you have any questions.
Good Luck!

Raise your desired idle speed by 200-300 rpm.

Then, you will have to turn the idle screw in far enough to get the car running and get it warmed up. Once you have it running and warmed up, use scanner and set it up to log IAC Counts. Turn off the car. Now take off the MAF and all the plumbing so that you can get to the TB. Now either drill a new hole below the stock one or open up the stock hole a little bit. Clean all the shavings and turn the car back on. It should idle higher now. Start backing out the screw until it stumbles. The MAF should still be off the car. You will see the SES light come on (no MAF) but dont worry about it. Make the hole alittle bigger. Rinse and repeat. Do this until you have the set screw all the way out (butterfly completely closed). Once the set screw is out and the car is running, now you want to scan IAC counts. They should be over 100 still. If you are happy with the 300 rpm higher than stock idle, then you can start dialing in the IAC. If not, now is when you want to lower the idle. If the car still runs, great. If not, make the hole a little bigger. Once you have the desired idle rpms set correctly, now you can mess with the IAC. Basically just keep making the hole bigger until you get down to 30-60 count area. If the idle is still eratic, you may need to work on the idle spark over/under corrections. Make minimal (if any)corrections to the over speed table and larger corrections on the underspeed table. After that, you should work on the RAF table (Desired Idle Air). I use LTIT+STIT to figure this one out. This should get your car running provided the cam wasn't istalled incorrectly or something is still unplugged (like the cam position sensor).
