Question Losing compression through spark plug threads?

Today I was poking around my engine and I decided I would get carb/throttle body cleaner and spray it around my lines and stuff looking for vacuum leaks. I have noticed that my car has a misfire. Rough idle, and an annoying vibrating feeling while accelerating that makes the keys rattle. It shakes more than a 4 cylinder engine should, so I have been attempting to find the problem. Well after spraying around, I got a little curious and started spraying around the spark plugs. Then my engine rev'd slightly, weird? So I stuck the straw in around each hole until I found which one it was. Both #2 and #3 have an effect with the carb cleaner being sprayed next to the spark plug. The engine rev's up about 200 or 300 RPM and it smooths out big time. How possible is it that I am losing compression through the spark plug threads, and it sucks in the carb cleaner when running? If I spray the cleaner on #2 for about 5 seconds, it will actually almost kill the engine (causing the effect of a rich mixture guess?) How do I solve this? Also, if I pull the spark wire on #2 while it's running, it hardly makes a difference in how the engine runs, whereas when pulled from any of the others, the engine shudders and almost dies. Any suggestions would be greatly appreciated! Thanks! 1989 Honda Accord LX.
