Ok. I am new to this site and was wondering if anyone could help. I do all my own work on my '79 Ford and have done basic maintainence on my Montero.
I have a 2002 mitsubishi montero sport 3.0 with 123,000 miles. Just started happening today, it was after i changed my battery, but i am not sure how that figures in. Drives fine, but when I stop (i.e. stoplight, parking, etc.) the rpm's get lower then just dies out. Unfortunately I have not been able to locate a manual for it otherwise i would have started with the fuel filter, and maybe i'm blind, but i can't locate it. Anything would help right now.
Thanks Monti

I really appreciate the advice and links. It worked like a charm. I can't believe that it was just a result of carbon build up. In the process I changed the air filter and the main gasket.
I made an adjustment to my accelerator cable, as there was a lot of slack in it. I also had to back the manual idle out a couple of turns. It was idling low, but constant in park. As soon as it was in gear, however, it dropped to just a couple hundred rpm's. It is still low when it is in gear, but I am hesitant to back off the manual too much.
Thanks again for the pointers! -Monti

To correct your idle or to check the base idle you will need a mut II and use actuator test item SAS mode (speed adjustment screw) which will take the iac stepper motor out of the picture and allow you to tell the pcm what the idle should be then once out of that mode the pcm will use the IAC stepper motor to keep the idle there such as when you turn on the a/c and p/s and headlamps and so on. hope this helps I am glad you fixed your problem though.
