How to clean a MAP sensor?
I pulled off the MAP sensor and there is oil crud in orange o-ring hole. I pulled out what i could see, but i'm worried some oil crap inside. Is there a way to clean, or should I just replace it?

I would just wipe it off and put it back. They are designed to be moisture (including oil) resistant. If there is oil present, it will simply occur again anyway. If you insist on "cleaning" it, I would only use a MAF or Throttle Body-safe cleaner, but do NOT spray it directly into the small sensing hole. There is a solid-state pressure transducer inside that could potentially be damaged by blasting into the hole or sticking anything inside. I would spray the liquid into a cup and then pour it on.

YES. 
As long as the hole is open, it should still function correctly. Tap it "lightly" on a flat solid surface and see if you can dislodge the goop.
