Joy, I had a very similar problem when I first installed my new engine last spring. I drove with my O2 sensor unplugged for a trip to Santa Fe and on the way back I got the rich, low mileage, stalling problem you've described. I reconnected my O2 sensor and that problem went away. I don't know why it took it solong to surface. Hope your problem is this simple. There are three connectors for my O2 sensor; one is flat and two are round. Just hook them up and see what happens. If after driving for a while nothing improves, get out and switch them around. Good luck. Warren Lail 88 Westy "Billy Bones" |
