I have a few things going on with my Rover that I would appreciate some input on, as it's my goal to complete them over the next few days on my vacation. I know there are several threads already dealing with some of these issues, I have gone over them with no luck.

1. Power steering pump squealing part time
2. Cruise control doesn't work
3. Factory (?) Hella front fogs inop. I have the dash switch with a 2 on it. As a note, the hot wire from the headlight isn't hot, so I can't check operation of the switch. If I hook lights directly to
battery, they work. Suggestions?
4. Cleaned MAF and re-seated all connections, truck keeps throwing lean bank 1&2 codes. Suggestions before replacing sensors and/or MAF?
