Geez that's horrible MPG. Hard to believe all that maintenance didn't fix anything.
I've owned it since 11/01 and never got over 13 combined driving (15 hwy). I've done plugs & wires twice, O2 sensors, synthetic oil changes (3000 mi.), egr, dpfe (x2), evr, pcv, flowmaster cat-back, kkm, bbk (newly installed), t-stat, coolant flush&fill routinely, and i'm sure there's more. EDIT: Ran a can or two of seafoam, too! FPR is fine and the injectors hold pressure the way they should.
I can't imagine that my fiberglas top and ground effects kit weight THAT much more that a stock v6, but they say every 100lbs = 1mpg. Based on that theory, i even tried removing the subs and no difference. If that is truly the case, and i have 250-300 extra lbs, there's 2.5-3mpg off the bat.
I tried babying it (featherfooting) for a full tank and NOThing! I think i got 150miles on 18g last fillup. During the summer, with combined driving, i got excited when the tripmeter got to 200mi. Now i'm just hoping that i can reach 150 b4 a fillup. This TRULY sucks!
