I also forgot to add that going up a long hill, if I push down on the accelerator to maintain speed, the motorhome drivetrain feels like it is shaking , lugging, or the engine is misfiring (?). It appears that under hard acceleration up a long hill that the engine struggles to maintain speed even with no load being pulled or carried. It's almost like upon this acceleration it feels like there is rapid driveline lash or pulsing, or high frequency surging (?)
This only happens when the accelerator is pushed and the coach downshifts to maintain speed up a hill climb.
As soon as the coach downshifts the driveline begins to very rapidly pulse like the driveline is surging, lashing, or shaking as the coach tries to accelerate or maintain speed.
Any ideas or input ??
My friend had the same symptoms in his V-10 ford pickup. Took it to ford dealer and independent shop without success. Third shop fixed it by replacing all the coils and the spark plugs.
