I have a 2000 CLK430. My yellow Check Engine light came on. I have two Error codes, They are P0173 & P0170. I changed the fuel filter but still get these codes.

NOW WHAT ???? :confused: :confused:

Does anyone know what to do next ????

Call me crazy but....
 

I was having the occasional "check engine" light...usually a day or two after refilling the gas tank. I put some mothers sealant protectant on the gas cap gasket and havent had the light come back on in a couple months....maybe its just a coincedence....
