Mitsubishi Repair: Stalling, mitsubishi eclipse 95, mitsubishi eclipse

Question
Dear Anthony,
I own a Mitsubishi Eclipse 95, 2.0 RS automatic. For the last year and a half I have been having a problem that has been getting progressively worse. On a cold engine, for the most part, my vehicle drives fine. When driven around for a while, then the vehicle is not used for about an hour, then driven again...the vehicle engine light comes on and stalls. This usually happens when at a low rate of speed such as coasting, coming to a stop sign, or at a stop. I even noticed this happens when idling in neutral when the engine warms again. The vehicle usually stalls once or twice and no more. When on the freeway (at high speeds) the engine light blinks on and off and usually hestitates...but that's it. I have taken it to 5 mechanics and their computers show that nothing is wrong. Some have even cleaned the  throttle plate and changed the cam sensor to no avail. This is a big mystery! What is going on here?  

Answer
Henry,
This sounds like it could be an emissions problem; possibly your catalytic converter is no longer functioning properly.  Flashing and intermittent check engine light can also indicate  random misfires.  This can be affected if the timing is off.  This can be caused by a number of things, including a malfuncitoning belt tensioner tensioner.

If none of your local mechanics can figure this out, you may want to have the dealership inspect the systems on your car to see if they can detech where the problem may be.  
Good luck!
