let see what kind of times your truck turns after its been manhandled by 4 previous owners that had their heads up there asses. my truck turned a 13.6 with 107k miles on the odometer..factory wires, cap & rotor, and plugs gapped at .40-.45. truck runs much better after a complete tuneup. i'm not making excuses, i'm happy with my ten year old trucks performance after 100k miles...Will your Ford even last to see 100k miles?
