car over revs just before it hits 2nd gear?? cold out though
it happens now almost every time....i start to drive off, not fast at all, but rite before it shifts to 2nd gear, it kinda over revs the engine a little. I dont remember it doing this last year....anybody else see this?

I'd give the ECU a couple days to compensate for the weather change if it was a big change.
During crisp weather, one of my cars will hit the rev limiter just before shifting, I tuned the mixture when it was around 60 outside, and the dense air causes a slight lean condition at full throttle.
