engine surge at idle speed


Asked by meathead Apr 22, 2010 at 08:35 AM about the 1999 Ford F-250 Super Duty XL Crew Cab SB

Question type: Maintenance & Repair

My Triton V10 started surging at idle speed whether in park or neutral but worse in gear. Could it be the MAF sensor or an O2 sensor?

i just went through this with my 2000 f250 CC Sb with a v10. i changed both o2 sensors and then cleaned the maf sensor, still happened. it was the idle air control valve- IAC- which is located on the back of the throttle body. hard to get to but simple and fairly cheap to replace...2 bolts. just be careful not 2 tear the gasket. also check your pcv hose assembly under the throttle body cuz they will have a crack in them and its not seen easily. hope this helps.
