i bought a pro comp dist and coil a couple of months ago. i was very happy with it till i started getting a low rpm skip,so i got a msd dist and coil. as i was installing the msd i noticed that two plug wires were about to fall off and a third was not clipped on the plug. lol.there is nothing wrong with the pro comp parts. but since i already installed the msd stuff i guess ill keep it.
