At about 75k mile, engine light came on. Injector 6 at max learning capacity. Took to dealer under warranty. They changed settings on injector(s) so light went out. Drove home and it seemed a little less get up and go. Mileage went down about 3 miles. About a year latter engine light, same injector (6) max learning. Truck runs great, no smoke. So I disconnected batteries for 10 min. Light gone. About 7 months later, light on. Same injector 6 Truck still runs great.
I don't want to take it to Ford. Bad problems with there workmanship at both Ford dealerships.
Any thoughts would be appreciated.
Thank you!
