What AE Tests to run during drive cycle: Bucking and Surging at Constant Throttle
Just got an oil change with 15w40 Rotella on the 97 7.3 liter.
Also just cleaned EPV tube and new sensor install.
Symptoms: I am getting a bucking and somewhat lesser occuring surging at highway speeds (@70 mph and 2000+ rpms)
I have been searching ad naseum for solutions.
I have AE with enhanced package. What live tests should I run while driving to help diagnose?
By the way my Transmission range sensor is in the yellow (voltage) but don't know if this would contribute to the symptoms.
