Re: 1994 Cherokee SE - Hi Idle Speed
Okay, How fast in rpm is the idle now?
At 190K, the intake gasket could have a leak. Which area, front or back? Tighten the valve cover or even reseal.
A way to check the intake (although messy) is to put engine oil in a squirt can and squirt it into the area that you think is leaking (with engine running) and see if you can hear a change in engine speed.
Also, check the IAC (idle air control) valve..
