cylinder #7

ok, so i got this bright idea when i got out my timing light to put it on every wire and see if one of my cylinders was poopin out. anyways. i figured that cylinder number 7 is firing erraticly. i guess that would explain when i got my codes pulled why my o2 and EGR showed up. And why i'm kinda blowin black smoke and why i'm sluggish up hills(@ 7200 feet). probably run and get a pressure tester and maybe even some new wires. I also put new plugs in last weekendwith a new o2. its a 89 302.
