oil change and hot compression test completed. Changed oil to some Valvoline VR-1 Racing 20w-50, which is helping it idle a little better. it's not jerking around as much, but still quite a lot. I did about 4 miles of several WOT runs and 60mph cruising to get the new oil warmed up.

compression results (all plugs out, fuel relay removed, WOT):

1: 100PSI
2: 120PSI
3: 100PSI
4: 132PSI

Head's gonna need to come off. Also noticed that I just started leaking some oil. HORRAY!
