Engine Performance problem
2003 Ford F150 6 cyl Two Wheel Drive Automatic 88000 miles
This Ford F-150 will set trouble codes P1131: Lack of HO2S1 switches- Lean (Bank 1 Sensor 1) P1151: Lack of HO2S1 switches (Bank 2 Sensor 2) and PO171 System to lean (Bank 1). If we reset this in the spring it will not come back on until the first time the temerature drops below 30 degrees. Any suggestions?
have the same problem?
