I hooked a scan tool up to my truck and it says im running lean, so i figured i change my oxygen sensor. its located on my 93 3.0 right at the mid section of the engine on the back side, i can see it clearly from below but there is one too many bends and i cant get at it. Anyone have a trick???? please help
