I need help with a 98 Ford Expedition 4.6liter 4X4. Recently the check engine light came on and after a quick OBD II scan I came up with three codes. During the troubleshooting I replaced the Bank 2 downstream oxygen sensor, throttle position sensor and the MASS Air Sensor. This cleared all three of the codes. Well sixty miles later the check engine light is on again this time with an upstream Bank 2 oxygen sensor and the OBD II Code of: P1151 Manufacturer Control Fuel Air metering. Any tech savy people out there want to try and help me figure this out? The truck has about 147k miles on it. thanks!
