I have a mitsubishi carisma mirage 2001,
My problem is when starting from cold the idle rpm is 1000, then after about 10 minutes the needle starts hovering up and down then it stalls.I have looked on your site and found there could be several causes, I have checked the hose that leads to air filter no visable splits. Could it be the main PCM relay and how is it mark in fuse box.
Many Thanks Terry

You may have a bad IAC ( idle air control) but try eliminating any vacuum leaks and 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.
