MAP and MAF sensors work very differently. A MAP sensor is an absolute pressure sensor, so it only has one opening towards the inside of the manifold. Theoretically it could get clogged by the air filter oil, but that would require your filter to be dripping with it. The air filter oils I know are very sticky and don't want to fling off the filter even when exposed to the typical inlet vacuum. A MAF filter can get contaminated much more easily, which is why there special MAF cleaners are made for it.
Instead of asking us mooks, why don't you just google "map sensor cleaning". I did and got a page full of direct hits.
I agree with this, though I doubt that'll be the cause. If you're already cleaning pressure sensors though, you should clean the ambient air pressure sensor as well. Both the MAP and ambient sensor are required for the ECU to calculate the inlet manifold vacuum, so both could be at fault if that measurement is incorrect.
