Purchased 05 F-450 crew cab 4x4 Powerstroke 6 speed. Has 7000 miles and since new has surged at 2000 rpm's. Dealer says Ford is investigating. Is anyone else having similar problem?
Not to scare you but your surge could emanate from a variety of different sources.
oil overfill
wrong oil
Bad EGR Valve
PCM
Bad fuel / filter
EBP
ICP
The list goes on. There may be some specific issues with your surging that could help pinpoint cause.
Please add detail if you can and i am sure others will chime in. For instance...is 2,000 RPM the always magic mark? Always in the same gear? Cold? Warm? Or Both? Recent oil changes. Well...you get my drift.
oil over filled on a 6.0 if it is to the high side of dip stick its too much, dealers are bad about overfilling. most of us here are only filling to midle of the dip stick. good luck
