My newest Mopar, not an A body

The plugs looked good, the wires were crap, the cap worse, and the rotor horrendous. I changed them all and it still misses. It's probably the intake gasket sucked in but I need to do a compression check to see if I have a bad hole. God, I hope not. I get to the brakes and someone had pad slapped it. The rotors were paper thin and it looked like they were grinding and someone threw pads at it anyway. I put on new pads and rotors and it stops perfectly smooth now. Got a stereo in it tonight. I have driven it two days now, and it seems to do alright except for that misfire on cylinder 5.
