I've never done this before so I'm not sure how it works. I have a 2000 Ranger with a 3.0. CEL is on codes P0171, 174. Scanner seems to show normal voltage readings for most sensors. The only weird reading is STFT B1-S2 99.2%. I have sprayed brake cleaner and starting fluid all over the engine and can't find any vacuum leaks. Any thoughts?
