Help with 2000 DII codes
It started with a code for a bad 02 sensor, bank 1 sensor one...changed it. Immediately got a code for the other side, bank 2 sensor one...changed it. Then started getting codes 150, 130 for running lean. Changed the MAF sensor...and wow: codes 1884, 102, 130, 150, 135, 155. Cleared them out but immediately get codes 1884 and 102 on start-up every time and it's runs super rich.
I'd start a fire under this thing and walk away but don't want the divorce that would follow since the wife loves this ride more than me I'm sure.
2000 DII w/104K.
Update: Put the old MAF back in and all codes went away on start up. Drove it while scanning codes and had 130 and 150 come back at about 50mph. Cleared them and they didn't come back the rest of that trip, but I suspect they're just waiting until I'm lulled into a false sense of security again.

bump
Latest update. Talked to Disco Mike and cleaned 02 sensor connectors as suggested (one side did still have a small bit of oil in it). Cleaned and blew out the connections very well. Took it for a ride and still get code 130 & 150. I'm at a loss. Any suggestions at this point would be appreciated.

Fixed
Thanks for all the help guys. Got it figured out and thought I'd update the results.
This whole thing took place over several months. First was a P0171. None of the local parts "box" stores had the front 02 sensor in stock...even Napa, soooo thinking why have them order it when I can order on-line and have it delivered to the door. I went to one of the "02 Sensors R-us" online sites and picked one up for 35 bucks. I've purchased 02's from them before for my other rigs with no issues so why not right?
Installed it and all seemed well then got PO174...ordered another, but by that time started getting PO130 (iirc). Installed the 2nd front 02 sensor and immediately picked up P0150. By this time I'm thinking...map sensor. Ordered it, installed it and got P0102, and 1884...dead map immediately. WTF now I've got 130,150,102, 1884. Put in the old MAF and 102, 1884 disappeared...huh.
Spent a LOT of time looking for intake/exhaust leaks and tracing wires...no luck. After thinking back over everything it hit me..the new 02 sensor had to be dead. Ordered in a set of Bosch 02's and no more codes.
I also fixed the three amigo's and the coolant leak at the throttle body heater while I was at it. Now that it's behaving and it's snowing again it looks like the disco will get to keep a spot in the garage for another year.
Bottom line: if it doesn't have a quality name brand on it...don't bother wasting your time and money!
