Engine problem
2001 Ford F150 V6 Two Wheel Drive Automatic 130000 miles

Engine missfires at gentle acceleration. Codes read lean fuel mixture right bank and lean fuel mixture left bank. I have tried coil pak, plug wires, plugs, fuel filter. Also, valve rattle when engine is warm at low rpm under load. Can you help me with this problem? Thank you

I belive you should check the 02 sensors. Also you may need to clean your MAF sensor.
