rec. fuel system clean. ethanol treatment to 1 tank of premium. ethanol blend in fuel causes build up fuel system , combustion chambers,exhaust, and causes increased wear to spark plugs. ford light trucks and SUV's from that year are known to have increased wear to spark plugs and coil boots on the left bank. i am guessing it has something to do with the exhaust set up. switched my personal vehicle to dual exhaust system to test the theory. so far so good.
