1994 4.0 5 speed 4WD Ranger -- I decided to check out an intermittent stumble and hooked up my tester to pull any codes. First I did the KOEO test and got: 522 -- vehicle in gear (it wasn't) 172 -- lean bank #1 173 -- rich bank #1 176 -- lean bank #2 177 -- rich bank #2 So far, so good...- Donnie strickland
