Clean the fuel injectors and replace the Oxygen sensor(s)
I am saying these due to the # of miles.

Hoping the elite group of towing team.net members can help with a mystery.
Subject: 1998 Chev 3500 Dually w/ 454 engine..
Problem: Absolute sucky fuel use. I don't mean "well you gotta big
engine, of course it's going to suck" kind of mileage. I mean like 3 to 4
miles per gallon. Empty. Not towing.
Tried: Dealer and independent repair shop evaluation. (One shop even had
a brand new, supposedly very high tech Snap-On digital engine anylizer. No
information from them other than "Well, the compression is good.") Result
is that all OBDII readings are within spec. Engine has around 49,000
highway miles. We put on a new fuel regulator, no help. (Thought there was
a TSB.)
It runs great. No one can seem to figure out why this is. Can anyone
relate any common experiences?? Any suggested areas to look at? Thanks
gang!
