Engine Performance problem
2003 Ford F150 6 cyl Two Wheel Drive Automatic 25300 miles
Service Engine Soon Light On showing Code PO171, PO174 too lean bank 1, and too lean bank 2. As I only have a little over 25000 miles on the truck I am kind of confused what the problem is due to the truck is running fine. It seems to be running the same as it was before the light came on. A mechanic used his OBD-11 scan tool, and cleared the codes only to have the light to come back on Two days later. The truck seems to me that there is no difference in performance.
Any help would be greatly appreciated.
have the same problem?
