OK, maybe I used two closely related words. The Hondas and Saturns he mentioned I would call "reliable" cars, but I expect my Jeep to be "dependable" on the trail, and on the interstate for that matter! Either way I just want it running right. It's now showing code 51 which is "Oxygen sensor, running too lean." I've replaced the O2 sensor and checked the vacuum lines. What else could make it run "too lean?"
