I have an 02 Milly with 80k miles. I' ve already had fun with the usual problems like the vacuum leak, timing belt water pump fuel filter and spark plugs. Right now I get a P0303 code. It usually takes a few days to show up after I fill up and add a fuel additive. When I changed the fuel filter there was a brown sludge oozing out. I figure I have some serious gunk in the fuel system and especially in the the tank. My gas milage has gone from 25 MPG to less than 20.
Does anyone have any suggestions as to how to clean up this mess? Thanks![/align][/align][/align]

there are shops out there that can do a complete fuel system flush for a couple of hundred dollars, you can have them do a flush or they can give you some good advices.
