Does anyone else experience rpm fluctuations while on cruise control going up a long slight incline. For example when im doing 50 with cruise set. If im going up a slightly inclined highway...and i mean slight. The car will jump between 2500 and 3k rpm's all the way up the incline. Not only does it drop but it almost sounds like the car just stops accelerating then re accelerates. Almost like its dropping off to shift then just changes its mind. Its also enough of a rpm fluctuation that everyone in the car looks like they are just pimp bobbin to some old school rap music. We look stupid is what im getting at.
