Is MAF cleaner like Gumout, carb cleaner?
The misfire seems to be random. There is sometimes a sneeze, like backfire thru the intake. The misfire clears after about half a city block and has good power; sometimes returns and sometimes doesn't. I am going to work on the car Wednesday as temps will be around 70.
For the MAF this is what you want, CRC MAFCleaner.
Here is a link from a site we are pretty friendly with, a buddy of mine over there posted some good pics of the process, only this is he used a q-tip, and carb cleaner, which you could do, but the o ring on the MAF, and the plastic housing could be damaged if you get the carb cleaner on it, so just use MAF cleaner to clean it.

Have you removed the EVAP line from the fuel pressure regulator and seen if it smells like gas, or leaks gas?
Watch this video, the part you want starts at around 1:50 so you can skip ahead if you want.
Question, you have not been loosing a lot of coolant have you?
I ask because if you have never had your LIM Gaskets changed to the aluminum framed gaskets, then chances are you could be leaking a little coolant into your cylinders, if you are not and the gasket has never been changed, then it is something I highly recommend doing if you plan to keep the car for a long time.
