^^^ I took the car to Mitsubishi a few weeks ago and they supposedly cleaned the throttle body and adjusted fuel/air mixture, etc......but didn't make any difference and the problem only got worse with time. Hot weather, air-con on, regular stalling.

A few days ago I took it to a local mechanic who again checked/cleaned the throttle body and "did a few other things". He said you can't touch the idle screw because it's factory/computer set. Car hasn't stalled since. Hopefully the problem has been fixed......touch wood.
