I have a '01 ML320. Last week got in it, started it up. Immediately noticed rough idle, and slow to go with higher than normal RPMs. Place it in the shop. Spark plugs and their wires changed, one was bad. To my surprize I have 12 plugs and wires for a 6 cyl. I would have never guessed. But anyway it didn't fix my problem. I have a fuel filter ready to change out but the problem is I don't know where the fuel filter is located. The question here is " Is it my filter". I want my good running car back.
