Final Approach
I have one plug wire that has the outside shielding scuffed away to expose the plastic insulation. It was rubbing on a metal hose ID tag. I have since solved the rubbing issue, but I guess I need to replace the wire. The wires I have are the older exposed metal shielding type.
I plan to do the 500 hour mag inspection and so it got me to wondering about just putting all new wires on while the mags are out. I guess the newer style Slick wire harness is about $400. Do plug wires wear out much? These have about 500 hours on them. In my old automotive days, we used to change wires frequently as they were cheap and brand and type mattered. I'm inclined to change them, but am I irrational?
The question you all might have is, am I having a problem? The answer is yes, sort of. Two issues with my Lycoming IO-360 A1A with Slick mags-
Thanks for the help!

- The engine has never run all that well LOP. The entire fuel system has been cleaned adjusted and inspected. The intake gaskets have been replaced. I installed new plugs. I have never done anything to the mags or wires. My injectors are stock and I'm not able as of yet to be able to run the GAMI lean test because of erratic fuel flow indications, but I'm working on that. The rough LOP could be the injectors, but it could also be ignition.
- I recently had the engine start running rough in cruise and continued through taxi. Number 1 cylinder showed normal EGT, but low CHT. That means either ignition, or valves. Did a compression check and it was normal. Number 1 is the cylinder with the damaged plug wire. Checked both plugs and found lead fouling in the bottom of the bottom plug. Cleaned it out and taxied back for a run up. Run up seemed improved, but unfortunately, I couldn't fly because on the last run up, my prop cable connection failed. When it rains it pours I guess. I hope to have the prop fixed this week and I'll fly it.
