This last post will keep the car running. What is happening is the car wont stay running when it is that rich so it loads upa nd dies at lights. Lower the ve table in the 400-800-1200 rpm cells by .7,.8.9 and you WILL see drastic improvemtns in the idle upon your next flash and restart...

I will be so damned happy if this works. This is one reason why I absolutely love this site. Tons and tons of information and people who are willing to help.
I will gladly buy anyone who has helped me with this a beer.
My range of emotions went like this
The last two of course is if this works out for me. I have a good feeling this time though.

So if it's still really rich and stalling out, take everything back to original and then reduce it to 60 80 90?
Basically if it won't idle I'll do that, but if it does idle I'll drive it around tonight and do some logging. When doing logging, should I stick to doing histogram display, gages, or what's the best method of logging. Or does each display option log the same thing, just displays it differently.

Well....... seems that my excitement was a little premature. Still have the same problem I was having before.
I've attached 2 logs. Thanks for looking and the help guys.
I did notice that my IAT counts went from 140ish to 95ish
Any thoughts?

Yes I did. I sent those messages to my email account and responded to them in the email I sent to your yahoo account.

Alright. The biggest thing that is bothering the hell out of me is that the damn thing refuses to idle where I set it at.
If it would idle where the program tells it to, it would run fine. I think so anyways since it idles fine when I'm holding the pedal down to maintain idle.
Can anyone think of any reason why the car won't try to idle at the speed I have it set to?

honestly i would try to lower the idle speed, higher idle speed desires more air, try to drop it down equally so that hot idle is about 850 rpm. first start up i had on my car was 850, 10g/sec on airflow, and i did the ve like you did and it idled fine. although with an auto your idle airflow will be different

ok.... found this from ls1tuning.com
I've changed everything in here like it says to....... except for
Idle Limiters --> Idle Air In Gear: All points 60C and up to 8.6
Where is this table at in HP Tuners? Is it the Engine-->Idle-->Base Running Airflow-->Idle Air Flow vs. ECT? If so, what values in there should I change? The thing written from ls1tuning.com was done for ls1edit so there are some differences I'm not sure on.
Idle Limiters --> Idle Speed: 950
Idle Limiters --> IAC Park Position: Raise all points from 40C and up to 21
Idle Limiters --> Idle Air In Gear: All points 60C and up to 8.6
Fuel --> Main VE Table: Multiply column 400 rpm by 60. Multiply column 800 by 80. Multiply column 1200 by 90.
Ignition --> High Octane Table: Add 2 deg to all points 400 to 1000 RPM, .08 to .32 g/sec
Once done with this program, start the car and check for surging. If the car surges, unplug the IAC and see if the surging stops. If the surging stops follow below.
Idle Limiters --> Idle Air in Gear --> All points above 60C to 9.2
Take the car for a drive and check your idle. If the car goes on cruise control reduce the Idle Air in Gear Table .2 (further if necessary). If the idle holds at 2000 RPM for extended periods of time reduce the P/N Airflow Decay table for all points above 10 MPH by 5% (multiply by 95) until this stops. Be vary careful on this table.
If car keeps surging with the IAC unplugged two more things to try.
Multiply Main VE table by another 95% (total reduction of 85%). Repeat until the surging goes away, or until the car begins to hesitate when you take off.
High Octane Ignition Table. Reduce timing for all points 400 to 1000 RPM, .08 to .32 g/sec by 2. Repeat, but don't reduce it any more than 6 degrees.
If your car still doesn't idle after this, then you have other problems, and should start looking elsewhere.

Drill the throttle body... It needs air to idle and get those IAC counts down. If you have a drill bit set, go one size bigger on the hole size until the IAC counts come down into the appropriate range.
