Misfire on the 5 Cylinder?

I've got an intrepid think it's a 97 with a 2.7 in it that's missing hard on the 5 cylinder. I can't tell weather it's missing throughout the spectrum or weather it's just at idle. Threw my scanner on it and brought up a miss on the 5 cylinder and then it brought up a random miss. It's burning oil as well which lead me to belive that it might have been a valve but I don't have a compression tester so I have no clue. Changed the plug and swapped the 3 and 5 coil packs and it the miss didn't change so I know the coil pack is good. Did a quick test by sticking my hand behind the tail pipe and it's got low compression. I know that's not accurate but it's better than nothing. It's got roughly 150k on it. and thinks to the heat shields over the manifolds I don't get the pleasure of taking it up to 2500rpm and shoving a crayon on the no.5 tube. Just wondering if anybody's got a good idea of what's wrong with it. If it were knocking I'd say it was a valve but it's not and I'm kinda stumped.
