I'm having a starting problem with my ML 320 (1999); initially it started losing power at acceleration over 60km/h, it will occasionally pick up speed or jack until it returns to normal and characterized by hard start during the day but surprisingly started easily in the morning.

Then one day it cut off while idling and to this day never started and only cranks.

These are the error codes that came out P0156-O2 SENSOR CIRCUIT BANK 2, P0161 02 SENSOR HEATER CIRCUIT BANK 2 SENSOR 2, P0110- INTAKE AIR TEMP. SENSOR 1 CIRCUIT, P0300 - RANDOM MULTIPLE CYLINDER MISFIRE DETECTED, P0301 CYLINDER 1 MISFIRE DETECTED, P0302 CYLINDER 2 MISFIRE DETECTED.

I was planning on buying a new MAF sensor, Crank Shaft sensor and Oxygen sensors which are four in the vehicle. Please advice me on getting it fixed. (Spark plugs have recently been replaced.)

Thanking You.

It appears that you are having a fuel issue: fuel filter and/or fuel pump. Purchase a Fuel Pressure Gauge and check fuel pressure at fuel rail. Should be 55 psi with key in pos. #2.

If low or no fuel pressure, change fuel filter first.
