1999 Jeep Cruise Control

[johntk]

I have a 1999 Jeep Cherokee Sport that has developed a cruise control problem. The car has 73,000+ miles on it. The cruise control is very lethargic in responding to acceleration commands.
This occurs when I'm returning to a set speed after disengaging and when pressing the Resume Speed control for accelerating to a higher speed setting. Also, the car loses speed on even relatively minor inclines and is slow to accelerate back to the set speed.
The cruise control worked fine until now. It feels like something is out-of -adjustment. Maybe there's a part that just suddenly wore-out.
Any suggestions?

Check for cracked vacume lines or leaking vacume acc. sometimes a small leak will affect the cruise control and not be noticed by anything else. I had the same problem and replaced all the lines under the hood and that fixed the problem. Hope this helps
