i noticed that my gas mileage was literally plummeting and attributed to my 2 failing injectors. the gas smell in the cabin started getting unbearable. upon closer inspection, what do i notice? there's a puddle of gas below my driver side door, dripping at an alarming rate. i really can't see the exact location where its dripping from because of the undercarriage. is there a gas line that is prone to rupture in this area?
