Wicket Mike - so in both cases when you put your stock "backup VE table" in the afr was stoich?? Are you Open loop with the MAF and SD?

I maybe have missed this, but when you did these tests, what was the commanded afr for each test and the actual? Also like bink asked, were you in open loop or closed? I would like to see this test in open loop.
I do not think this is related to Backub VE table as there is no Backup VE table in the 2002 OS I was using when I had this problem. Although I have a '99 C5 which originally uses this table...

i just tested it out again today and now its now running lean with the MAF plugged in, but i swear it did yesterday. :-(
i hope we can get the update soon, pulling my hair out

Try this. Pull the fuse or disable the A.I.R. pump, by tuning and see if it's really only a false reading.i just tested it out again today and now its now running lean with the MAF plugged in, but i swear it did yesterday. :-(

Shoots that idea....
Yea, I don't have an AIR pump installed anymore either. Seeing the same thing at cold start-up.
