I have a ML320 2000. It lost acceleration, power. I hooked up a code reader it said P301, P304 CPS sensor was changed didn't help at all. Replaced the fuel filter, ran ok until it warmed up then it chugged and coughed and died. Fuel pump seems to have a lot of pressure. Any help would be appreciated.:surrender:

I am trying the dry gas. And keeping my fingers crossed.
Well she is all back together. I ended up replacing the fuel pump too. That's alot of work! I picked up one at a salvage yard for 110. and she seems all better. Thanks to this site I saved a lot of money. MB wanted 508 for the pump, 158 for the filter and 800for estimated labor. Thank you for your help.
