My F150's at a local garage. The truck's been misfiring, mostly around 1500 rpm. The mechanic (who I've always trusted in the past) says it needs new spark plugs and wires. Is this a little early? I bought the truck used with about 42,000 miles on it. The mechanic quoted me $250 to do the job, should take about 4 hrs. Currently scheduled to do it Friday.
Also, is there any benefit to using high-performance/low resistence plug wires? As long as he's replacing them, maybe spend a few extra bucks and get the best? I use the truck for everyday driving (20 miles of highway) with little or no load, and occasional misadventures in the Rockies.
Happy New Year to All, Scott
