I cant remember what I had replaced about 5-6 months ago, seems like it was a sensor. My 1993 Ford Explorer is not running or idling at normal speed. When I pull up to stop it is like it stays engaged and wont idle down. Then when I 1st start it it wont stay running at all. If I have to be stopped at traffic lights for any amount of time I have to put it in neutral and keep the engine idled up high. Seems like it was the map sensor but then again its almost like it was oxygen sensor.
Listen for a hissing noise(vacuum leak around the pcv elbows or upper intake gaskets) this will cause a high idle set off lean codes which will say bad o2 sensors alson check idle air control valve which is located by throtlle body this wil ... 1993 Ford Explorer Limited
