As my speed increases past 65mpg on the highway, I notice that the engine begins to sound and feel a lot more course and rough. Any suggestions as to what might be the cause? 99 Jeep Cherokee.

Try the basics first: for a 99 that would be cap, rotor, wires and plugs. Also try cleaning the throttle body and changing the air filter. Even if that doesn't solve the problem...a tune up never hurts. Wink
