ML320 fuel codes
 
Have an ML320 - '98.

Fuel trim malfuntion- both banks.

Any info or general direction is appreciated.
Thanks

This means that the fuel computer(ECU) isn't able to adjust the fuel mixture! Very common failure. Either incorrect fuel pressure OR the mass air sensor has taken a LEFT turn! The air mass sensor is the most common failure, part number 112-094-00-48(list $275.)
