high fuel trims
Back 3 months ago I zeroed out all of my fuel trims buy adjusting the MAF sensor and they stayed zero. Now 3 months later I have all positive fuel trims some up to 9%. The only thing that has changed is the air filter and the temperature. Do you think that could be the variable that changed or is it a sign of something else.
Ex. the combined fuel trim at 600rpm 0.15 engine load is at +8.1% |

fuel trims at idle can vary quote a bit with large variations in intake air temperature.
Add 4% to maf scale in that low end area then 2% to thexarea jist above to smooth it in |
