My future brother in law has a 2000 5.0 V8 Explorer. It had been running rough and had a check engine light on. I changed out the plugs, but did not do the wires on the advice of the man at Napa. It still was running rough, but better than before. My fiancee's father took it to the dealer on Monday, and they changed 1 defective wire. Is this just asking for trouble, not replacing the whole set... This vehicle has 96000 miles on it and the wires are originals.
Thanks!!
Scott
