Need Help.....E420
I own a 1997 E420 and I need some help. I’m getting an occasional ‘Check Engine’ light on the dash. Another thing it has done is at idle the engine revs from 800 rpm to 1,200 rpm. It has only done this twice in the last month. My OBDII error codes are as follows:
P0507 Idle control system, RPM higher than expected.
P0170 Fuel trim malfunction (bank 1)
P0150 Sensor circuit malfunction (bank 2, sensor 1)
P0173 Fuel trim malfunction (bank 2)
P0455 Evaporative emission control system leak detected (gross leak)
Any help would be greatly appreciated.
