2012 Ford Expedition EL Limited 5.4L Hesitation, Surge
Posted to Ford Driveability on 10/12/2016 18 Replies

Concern of a surge. Test drove and under slight acceleration there is a surge. Very consistent. Surge a second, go a second if throttle is just in right spot. Looked at MAF, Fuel trims, knock sensor, oxygen sensors, tps, etc, did not notice any abnormal issues...
