Saab 93 2.0T 2008 odd positive fuel trim was created by ComorH
Hello! I have been scratching my head about this for weeks, and have investigated as much as I can to no avail.. hopefully someone here may have some ideas!

I'm getting positive long-term fuel trims which increase with rpm, starting at ~+3-4% at idle and then peaking around 1500-1750rpm at ~+14%, these then drop down slightly above that to ~+6-7% at steady cruise. Under boost they still seem to be around +6-7% or so.

TIA!
