The pesky 3% LT fuel trims

A soft failing MAF was most of my issue. However, it bugged me that my LTFTs were still centered around 3% and not 0%. Took apart everything on the intake side to double check. Sure enough, I missed something last time. The oil tube o-ring was crooked and sticking out. Put in a new o-ring and seated the tube properly. Now the LTFTs center around 0% and even go negative sometime.

Yap, the brighter light helped.
