I checked out my plug wires recently because my car was never idling smooth and it has developed a miss.

Anyway, I see rust buildup inside the plug wire itself and I know that can't be a good thing. Anyway, the wires I have are old A/C delco wires, so I am thinkuing I might just get the same box again...what do you guys think?

If I replace the wires would my car be smoother or no?

I have done just about everything else except for that, fuel filter change, O2 sensor, plugs, distributor cap and rotor TPS...

 

Plug wires are very inexpensive infact you can get a premium set for $30 at autozone with lifetime warranty that means you can replace it whenever you need for free, for ever. They have $20 ones that are lifetime warranty too. Never reuse disposable parts that are "iffy" we all learn that the hard way eventually.

 

Ahhh, Yaaa
