You have a 3.1 not a 3.6.

First eliminate all vacuum or air leaks in the system (very important)

. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Yes on HT's suggestion. If this ONLY happens with using brakes add hose, check valve and booster to your vacuum checks.
Booster should hold, engine off for quite some time.
Try this: Engine off push brakes till pedal is hard it's lost all reserve boost. Now start it feel boost while pressing on brake should feel it come back. In doing that does it change the idle speed or make it stall? Play with brakes just sitting still idling for the same it really shouldn't mess up idle,
