Mileage and Multiple Codes
Hi, we have a 2005, we have been seeing our gas mileage decline. It has gone from high 30s per gallon now to low twenty's now. We went to advance and had codes read. Came up with....
P0121-Throttle position sensor
P0130-02 sensor bank 1 sensor 1
P0171-Bank 1 system too lean
P0300-Random multiple misfire
P0420-Catalyst system below threshold Bank 1
P0455-Evap emission system leak detected(gross leak/no flow)
P0461-Fuel level sensor A circuit range
P0520-Engine oil pressure sensor circuit
P1680-Acceleration Pedal system performance.
Engine also sputters after a tank fill up. What in the world is wrong with this thing now?
Thanks your your reply
