The difference begins to show up when the temp drop into the mid 30's and the info.center confirms an avg mpg of 11. I believe the engine is not getting enough air through the intake, but the engine runs well and does not smell like it running rich. I've also tried 93 octain, no improvement so far. What could I be missing here, besides the air filter compartment,is anyone familiar with the lower part of the air box. thanks. I have the 3.5L V6 and hate to take the air box apart blindly. Thanks for any and all help.
