2003 F150 Check Engine Light
My 2003 F150 when you first start out seems to be missing-also when you turn the heater on the temperture guage rises. When you turn the heater off the gauge goes back down. Also when the heater is on you can here like a beep. Is this my oxygen sensor, temperture gauge, what?
