>my tarus does not idle well. It idles roughly at a stop and seems to be missing a lot. I shift it into neutral while sitting at a light and it idles better. It really runs bad when I am driving on an incline. Misses and hesitates when I push the gas pedal. I shift it out of overdrive to drive to get more power and help keep the lugging down to a minimum.
The P1506 code means that the engine idle is out of factory specification. Sometimes the Idle Air Control (IAC) may have carbon built up. Disconnect the car battery, remove the valve, clean, re-install valve, and drive the vehicle for about 5 minutes with the headlights and A/C ON to get the idle relearned. If the problem persist, the IAC valve may need to be replaced. Read more: https://www.autocodes.com/p1506_ford.html
