Just under 200K miles. Wagon

I got the care from my father when he picked up a new ML350, and 4 months ago. It has had the problem since I got it.

The Dash has a check engine electronics message.
I will get an OBD an pull the codes.

I believe the fuel filter has already been replaced.

I also have a 1994 E320. The MAF fails on that about every 18months. The symptoms are almost the opposite of this.

If a CEL light flashed i have never seen it.


Thanks.
