What could cause rpms to dip and bounce back in1998 Jeep Cherokee?

Question

When I take my foot off gas even coasting downhill I feel a hesitation and see the rpms drop but then bounce back up to normal level. There does not seem to be a fuel problem as I do not feel it missing or running rough. I have had a few strange electrical things going on that we can't track and the OBD shows no codes. Could these be related or just coincidental?

Answer 1

I've had the same exact thing happen with our 1991 F250. A friend thinks it's shifting between gears. I don't buy that, but I can't think of anything else.

Answer 2

Could be internal in transmission (throttle pressure) or could be as simple a tps sensor (throttle pos. sensor)
