You're right about the compression, shouldn't be lower than 100 psi.
keri_anne, when you changed the plugs, did #2 plug look any different from the rest? You can check spark at the plug end of the #2 wire, then check it at the coil. If you have spark at the coil but not the plug end, then you have a bad wire. Tempting as it is, don't overlook the simple things! Wouldn't be the first time a wire has gone bad in less than a year. The plug end of the wire on my Jeep recently came apart inside the rubber boot and it was less than a year old.
All in all, I second (or third) the advice so far. Good luck tracking down that problem.

those are the spec for KOEO. The spec you place is for KOER
i could elaborate more if you like on deadpaning and isolating the cause but you need more specialized tools. Keri just check those first. i rule out, ignition module since you have only 1 cylinder. Im lead to believe you need only 1 coil pak. Easy way to check is to swap the coilp with the other two and see if the misfire goes to the other cylinder.
