Not sure if this is where I should start?

Newbie Benz Owner. Own a ML320 - 2003

When should I take her in for a tune up? I have 50K miles. Since I have had one of my spark plugs warranty replaced it runs a little rough at idle & on stops at the lights....

I run premium gas & think there might be some carbon starting to build up hence the rough idle shaking.

Also I haven't noticed anything in the owners manual about chnaging the air filter???


What have you all experienced?

If there any after market product I could use that is safe? Or is this work for the dealer....

What would your dealer charge for something like this in LA?

I thought the dealer checked that stuff with Serive A or B Maintenance?

RE: General Maintenace - Gas Gauge issues

Took her to the dealer. Changed out my fuel filter. I had 60k miles. Service Guru stated that it was time for replacement of filter per MB maintenance specs.

Runs smooth now ,but gas gauge jumps around? I fill up the tank & after I drive to my destination & turn it off & get back in to depart it shows I'm on empty or half tank & I only drove 1/2 mile. hahahahahaha I keep reset/ rebooting gauge via plug in wheel well on rear drivers side as describe in "reboot gas guage" thread on this forums. It still jumps around on me.
