Car leans out taking off from a stop ??? I noticed a week ago that when taking off from a stop, there is a pretty big hesitation (need to give it a lot more gas then usual to get rolling) and the AFR gauge goes to 17+AFR ...probably past that since the AEM AFR gauge goes blank and shows - - on the gauge until I'm rolling and regains the signal. Once the car is moving it feels fine. Fuel pressure looks good around 55psi @ idle.
I'm really not sure where to start looking to try and figure out what's causing this issue. The car is a forged 347/F1C procharged C5 making 18-20psi (depending on weather) 100% Alky. A4 (fully built) with a Yank SS3600 stall. the car is MAF tuned.
TIA

Yeah, it just started doing this a little over a week ago. I'm not sure that the cooler weather is a factor because we had a few warmer days and still the same issue. I'm going to scan the car this week when I get some free time.
That would be best..could be a number of sensor's causing the problem. Assuming the car is closed loop it could very easily be a bad 02.
