Bad mileage and gas smell

edited December 2011 in Repair and Maintenance
Dear Ray and Tom my van is using way too much gas.I can smell gas at tail pipe and can feel the express pressure when it explodes in exhaust pipe.I changed plugs,wires,distributor cap and rotor and still exactly the same thing .It also floods out easy if i dont keep my foot on gas pedal at a stop.I been told by people that it could be one or more sensor but is there a way to tell if one is bad or what .Im a poor working man and cant afford to throw 100 dollar bills at it. If you could narrow down what sensor(s) I should look at where they are located I would greatly appreciate the help
