Joecar you are awesome! When I get home this afternoon I'm going to plug back in the Rear O2's and turn the MIL's back on, and see what that does for me.

THANKS SO MUCH EVERYONE!!!

Set "MIL" and "Not Reported" to make the readiness tests say "Ready".

In Arizona you get one free "Not Ready". Note the left center of the inspection report. I was in compliance even with the EVAP "Not Ready".

I have had problems with the EVAP diagnostic in the summer. This test will not run if the IAT or the ECT is above 86 deg F. They must also be within 16 degs of each other. Make sure your cold start meets these requirements.

Good Luck

Okay so I finally found some time to look at my tune. lol I was a long day. It seems that all of the O2 codes were set to MIL/NOT REPORTED, but the AIR ones were set to NO MIL/NOT REPORTED. So in the morning I will load this tune and try the GM driving deal and hopefully that'll fix my emissions problems.

Might want to lower B4205 to enable closed loop fueling also.

Might want to lower B4205 to enable closed loop fueling also.

John, should I put that back to the stock temperatures? Or set them at a temperature that I think I will reach during a driving cycle?

Thanks,

Do they do the sniffer...?

[CoryF]

Joe, no sniffer. They just plug in and check the MIL light, the Readiness tests.
