1993 Jeep Grand Cherokee


#1

Car runs ok but has very rough idle. Replaced the idle air control motor. Still no good. Good compression in all cylinders.


#2

How about other maintenance items like air filter plugs and wires


#3

All of the normal stuff has been done. Could this be a plugged catalytic converter?


#4

no try cleaning the throttle body and mass air flow sensor and check for vacuum leaks.
