Try increasing the tire pressure by a few pounds and keep accelerations under 2k while in town.

 

I get about 13 mpg butI guess thats what everyone gets. Thanks

 

DO NOT buy or USE THIS PIECE OF !@#$ potentiometer. It will set code code DTC P0113 (Intake air temp voltage too high).

Basically, this is a variable resistor that attachs to the IAT sensor harness, allowing the voltageto be returned high to ECU making the ECU think that it is freezing cold weather and therefore richening your mixture.

But the ECU after multiple cycles will compare IAT to ECT voltage (engine coolant temperature) and it will set a fault code if the variance is higher than mapped.
