How old are the wires?
Did you check the resistance of the wire?
An easy test to find out if the wire is bad is to swap #3 wire for the #1 wire.
If the misfire code is now P0303, the wire is bad.

well we removed #1 and #3 and there was no electricity coming out of #1 so we had to replace the whole thing. the wires were probably stock from the previous owner and so was the coil pack. it's definitely running stronger now and smoother. i'm liking it alot.
