High positive fuel trims during cold start, normalizes after a few minutes of driving (as you can see near the very end of the datalog).
Anyone know what the cause would be? Tuner is taking a long time to get back to me. Not sure if it's a vacuum leak since fuel trims start to look normal when car is warmed up..
Fuel is with E85 w/ Flex fuel kit.
