Argh...anyone seen their AFRs drop off like this?
I start the car and it runs fine...just idling...then after about 10 seconds the wideband reading just starts to drop and starts running rough - vacuum is at 20 when running good then drops to about 15 when AFRs get down to 10:1. I've tried searching around but don't see anyone else having this issue. anyone have an idea of why it's doing this? I've attached a log and my .msq
Thanks!
Thanks!

Go to Exhaust Gas Settings. Normally it's set to not allow the MS to alter the AFR according to the AFR target tables until above 1500 rpm. I was having some trouble getting the idle to be spot on all the time in different conditions and with the car at different temps so I changed the EGO to be active above 500 rpm and gave the target tables a bit more authority by changing it to be able to alter fuel by up to 7% instead of 5%. My idle is dead on now all the time.
