help with code!!!!!!

[whiteboy98gt]

I am pulling my hair out trying to figure out why I keep getting the 0301 code (misfire cylinder 1) has anyone else had this problem and what fixed it? I have replaced all spark plugs, injectors, MAF, TPS, coils, fuel filter, vacuum lines, etc Please help!!!!!

sounds like it could be a mechanical misfire


you might want to check the compression on that cylinder

Is the wire routed around something that could be interfering with the voltage going through it? I know on my wife's Jeep, there was a TSB to re-route the wires if you had any misfire codes come up, and it involved only crossing other spark plug wires at 90 degree angles, no wires running parallel within a 3/4" of each other, etc.
