So, I tried turning the van off and on again quickly. The symptoms you described below of things resuming normally and then messing up again soon after were exactly what I experienced. I checked the 3 wires coming from the new O2 sensor. The single wire had a little corrosion on it, so I cleaned that up and the AC semed to work fine for a few days, then returned to the same symptoms. Rechecked that connection again and cleaned it a little more (still in good shape), but didn't make a difference. Fore good measure, I cleaned the contacts of both ends of the trans-chasis ground strap (since it was on my to-do list anyway), but still no luck. I think it would be highly unlikely that I have a bad O2 sensor since it's new. What I could see that would be more likely is a leak int he exhaust pipes before the 02 sensor or I've gummed up the O2 sensor from running too lean at times. Thoughts? (as I dig out the Bentley to start chasing down the O2 circuit for bad conections or opens).
