colder weather can have a fairly large impact on tune...that may not be the only thing but its something to look into exp if you were tuned during the summer. small vac leaks can do it as well. large vac leaks tend to mess with the maf so much that it just goes all wiered on ya.

im banking on the issue to be more than one thing.

try to reset your ecu, cuz closed lopp fuel trims like to find their way into open loop and well if u have a -20 fueltrim well yea...

cburglb34

also speaking if your using the emanage blue count that as the problem cuz it tuned off the maf and well now that its colder readings are different

exhaust leak is a very likely culprit as well

cburglb34

so many factors

I drove last winter it was fine and i was tune in summer.

Chances are if its reading lean in boost, your actually lean in boost. Add fuel if you tune yourself, until you find the problem (if there is one)

Usually lean or rich condition set off my cel like before but this time it didnt Im think the wideband could be going bad I just got it this year..
