engine shaking problem

[johnny5]

AND YES I SEARCHED! ok so my problem is is that my engine shake, it idles fine, no jumping or anything. it was fine earlier now it shakes and theres a noticable loss in power. it did go back to normal for a couple seconds but then went back to the loss of power and shaking. any ideas? i replaces the plugs as they wer burnt, didnt help, my friend thinks it jumped timing but i dont think so. my exhaust kinda sounds the way an sti sounds, i had this problem when i had my jetta and it was only when it was wet out so im thinking this may be the same thing. so im gunna try doin plugs and dist cap and rotor button. but please if anyone has any ideas let me kno. when i searched everyone had shaking but also a tach bounce. mine just shakes and has a loss of power.

ok so i got to tinkering today, plugs wer eplaced yesterday and i swapped wires, def not it, i narrowed it down to cyl1 i can unplug the wire and it runs exactly the same, sooo im either not getting any fuel to it or spark. i tried to et my fuel rail off so i can swap injectors to see if that is but it wont come off and i cant figure out why, mor tinkering to do there later. and as for spark check well i dont have a way to do that lol any thoughts?
