Cylinder 4 scares me. >.> =/

I'm afraid that it's bad news from here on out. Your problem is likely located in worn rings, valve damage, or the headgasket. The generale rule of thumb is that if your compression is low AND constant across multiple cylinders, the headgasket is to blame.
My advice to you, and I'm sure many people will echo this, is to perform a leak-down test in order to narrow down the loss of compression. The idea is that you fill up the combustion chamber with compressed air and listen/look for where it's escaping... hissing at the intake or exhaust suggests the respective valves, bubbling in the radiator suggests headgasket, and hissing at the oil cap or dipstick tube suggest piston rings (usually)

Re: H22A compression Test Results

The correct way to do it would be with the engine warm, all spark plugs removed and throttle wide open. Still your compression is so low I doubt it would make much difference.

Good luck
