Umm.... :?
i have NFC what readings your IAC is in but they should never be below 50 at idle....your readings are VERY weird
LTFT'* should be close to 0.0 at WOT but i see various LTFT'* on my car too
your 02'* are LOW
Timing should be at 14-15 at WOT
Pete are you coming to Bills this weekend?

Well I know where things SHOULD be.
My LTFTs have been as low as 0.7 and 3.1 while just cruising normally, but WOT is 6.2 always.
I don't understand my IAC readings either. On my CP9110 it displayed 2 digit numbers. This gauge is showing 5 digit numbers. For example, while driving I will have a reading of 17249 on my IAC. :? IDK WTF that means and the instruction book doesn't give units. Does anyone know what these mean??
I really think my misfires, though not very large misfires, are a major problem here. I'm guessing that'* why I'm running lean. I'll have to check out my ignition this weekend.
I'll be at Bill'*. Friday night if possible.

Your IAC numbers are off the known scale according to the 4-5 Aeryoforces I've seen.
Let'* do this.. we can't diagnose anything this way. Get a couple more days out of it.. get to my place and we'll get a full blown scanner on the car.
Friday night TJ, wife and brother are arriving. Pat as well.. and now Petimus... LOL it'* going to be an interesting weekend.

FYI - I might stop by on Sunday with the wife and kid for a parts delivery. JT'* bro needs a mirror backing plate and Gumy needs the mirror glass. The plan is to stop by and drop off parts, then introduce the family to Robin.... We're taking a ride to Palmer to go test driving. FYI2 - Bertera Chevy has two Black GXPs and one 03 SSEi. We're going to look at a couple of GTPs. ![Twisted Evil](https://www.gmforum.com/gm/images/smilies/icon_twisted.gif)

Driving around town tonight, watching my LTFTs. Getting some WACK readings. Cruising around 30mph always has gotten me 3.1 and sometimes 5 at the highest for LTFT. Tonight just idling I saw 10.9+, and a max of 15.6. ![Shocked](https://www.gmforum.com/gm/images/smilies/icon_eek.gif)
Got some gas, drove home, and they were on the opposite side at –10.9 and –15.6.
WTF.![Shake](https://www.gmforum.com/gm/images/smilies/shake.gif)
EDIT: Wait a minute....I wonder if this is because I was really low on fuel, basically driving on a 1/2 gallon of gas when I saw 10.9 - 15.6. After I filled up with 17.5 gallons, I saw the negative readings. :?:
