Hello friends. This last week a hesitation has developed in my 2006 Liberty 3.7 . As I am cruising down the highway, 55-65 mph, every now and then the jeep will momentarily feel like it loses power. It reminds me of hitting a soft spot on a chip and seal road, only I am on a highway. just lasts for a second, and then resumes. May do it once in thirty miles, may do it every twenty seconds for 3 or 4 times and not do it again for a while. No codes are thrown, and transmission fluid looks nice and pink. Does not feel like an engine misfire, feels more like a momentary increased load on the engine. any thoughts?
