I have an 06 commander 5.7. When I drive does not matter what speed. Can be driving 20 mph or 80 mph. I reach my desired cruising speed and try to just maintain that speed. I notice that something engages and puts extra load on the motor, I press slightly on the gas pedal and what ever it is disengages and feels like the jeep goes back to normal. As long as I keep a small load on the motor. Any ideas?

Please read this and fill in some of your details and make a signature with your Commander details. (year, model trim, engine, 4wd system, etc.) It is nice for us know what your Commander has in it so we can better help you.

is the AC on? is it "in" the transmission or purely engine load?

Sounds like your MDS kicking in to me.
