Other week it started hesitating/studdering under hard acceleration and started throwing a cylinder #4 misfire code. I switched the plug wires with cylinder #6 and #4 tried a can of SeaFoam and was actually impressed that it (seemingly) took the studdering away. Now today I again noticed this same studdering and got another engine code......this time cylinder #6 misfire.
I did notice that all of my plug wires have numbers printed on them except for one....the one that was being used for cylinder #4 (which is now on cylinder #6). I'm thinking that it's time for new plug wires.....what do you guys think?
