I get between 23-26 driving around town. Last year I drove from Denver to Tulsa, averaging 31-33 with 4 guys in the car, cruise control at 80 mph. Verified with OBC and the old fashioned way.
This weekend I replaced a horribly cracked lower intake boot causing my MPG to drop from my 25-26 avg to 23-24, does anyone know if this is just the MAF adjusting for the long period of a bad lower intake boot? You could stick your pinky thru this thing. Oh and the "whistle" problem was fixed with this repair...
