Which codes did you get if you remember? P0171 or P0174 possibly? I have been having this problem for a while but only at full throttle, didn't matter what gear I was in (auto). Seems like if I back off the throttle a hair it goes away a little and I can still accelerate but just not as quickly.

I honestly don't know how my tuner got a dyno run on my car if it runs the way it does for me.
