Engine surge at constant speed
New member here........... 2003 7.3 F350
Over the last week or so I've noticed a slight surge or flat spot when maintaining a constant speed of 40 mph. This is not indicated anywhere other than the seat of my pants. It feels like the truck is headed into a stong gust of wind or driving through a puddle.
This resistence will go away with the slightest pressure on the accelerator or deceleration. Any ideas?
