Hello and welcome to Just Answer. My name is \*\*\*\*\* \*\*\*\*\* I will be the expert to assist you today. I'm sorry to hear you're having issues with your Mitsubishi, I know how frustrating it can be. Because I am not there nor am I aware of your level of automotive expertise I may need to ask questions in order to provide the best possible service.
You mention the vehicle "Stalls" when coming to a stop. Which Engine / Transmission do you have?

I have an idle just above 600 RPMs and when I'm idling it tends to dip below and violently shut off. When I turn on the air conditioner the idle go slightly up but I still have the issue where it dips below at idle and violently shuts off2003 Mitsubishi Montero limited

OK, you mention you've had many things done including the Throttle Body replaced, a Tune up twice, A fuel System cleaning and a new Crank Seal by the dealer and still you have this concern. I think you need to approach this differently. It sounds like you may have an issue with the "Torque Converter or the Torque Converter Lock-up Solenoid" not releasing. This will cause the vehicle to stall similar to coming to a stop in a manual transmission vehicle without stepping on the clutch.

InterestingWhat is the fix for this?

A failed Torque Converter or Lock Up Solenoid should trigger a DTC and I know you mentioned there is no MIL so it is possible that you have a "Plugged" Transmission Cooler and it needs to be repaired or replaced. All of these will cause the issue you have.

I'm leary about taking it back to the Mitsubishi dealer as I thought they would be the experts and fix the problem but they couldn't even duplicate the problem.

The Lock Up Solenoid is located in the Transmission Valve Body and requires the entire Valve Body to be replaced (Be careful with anyone saying they can only replace the solenoid, usually doesn't end well for the transmission) the Torque Converter requires Transmission removal and in a 4WD it is a major job.

Yet this does change new light on the situation. What do you think the average cost of this job would be?

I agree about being leery to return to a dealer who could not help. If you're OK mechanically I suggest a process called a "Capacitive Discharge" It is used to clear electronic memory and you'd be surprised what it can cure (Kind of like a stuck computer window)

How would I go about that process?

The Capacitive Discharge process is below.
1. **Disconnect the Battery Negative Cable and lay it off to one side**
2. **disconnect the Battery Positive Cable and lay it off to one side**
3. **Touch the Bare Cable ends together for 20-23 seconds**
4. **Reassemble in reverse order**
5. **Start the vehicle, you'll know immediately if there is a change.**

Please also be sure to verify the Transmission Fluid level and condition. This is critical to the smooth operation of the transmission and 4WD systems of the vehicle.
Transmission repairs are always costly so I would suggest you get a second opinion if none of the above helps. Please keep me updated to the result and do not hesitate to reach out if you need any further assistance.
Have a safe and prosperous new year!

I old attempt the process as you described above. However it would be about an hour or so. This is my first time only four-wheel drive vehicle any suggestions on how I would check the four-wheel drive transmission fluid levels?

PLEASE BE KIDDING! that will cause many multiple issues and the vehicle will become unusable.
The transmission and differential fluid levels are checked from underneath, can you get the vehicle in the air?
Customer

No, I usually take it to my go-to mechanic for anything that needs to be done underneath. He's the one that did the tune-up and throttle body replacement.I'll have him check it.She's not an experienced technician but for minor jobs he gets the job done.

OK, have him check the Fluid level, and condition and ask him to do a Flow test. That will tell you if you have a plugged cooler. It's a simple test and should not cost much. Just looking for the flow level through the cooler and transmission pump function. Keep me posted to the results. I'd like to hear.

I will. Thank you.
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.

My 2003 Mitsubishi Montero limited stalls when slowing or approaching a light after warming up for about 25 to 35 minutes it does it about four or five times a day it's very frustrating with no engine light. I've taken it to a Mitsubishi dealership and spent $600 for them just to do a fuel system cleaning and a crankshaft seal replacement repl Mechanic's Assistant: Is the check engine light on? Does the Mitsubishi stall at idle or when driving? At idle. No mil light Mechanic's Assistant: Are you fixing your Montero yourself? What have you tried so far? I've taken it to a Mitsubishi dealer and left it for 3 days with them and all they could come up with was a fuel system cleaning and a rear crankshaft seal replacement. Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I have 106,000 mi on the car and I've had the throttle body replaced two times and a tune-up
