My mPG has taken a drop off recently, I am at 2" lift with 30s stock gearing I drive 99% city no freeway at all. I used to average 250 miles before my fuel light came on and put in 15 gallons of gas between fill ups. Now I am down to 200 miles before my light comes on which is ruff. I didn't think 30s would need re-gearing, my MPG was steady for a while after the lift and bigger tires and has been dropping off(before the winter gas mix came around).
I have a new coolant temp sensor, main o2 sensor, CPS, fresh oil change, fresh air filter, cleaned IAC, recent plugs and wires, rotor and cap, distributer is newish and a bunch of other stuff.
