ur engine timing is off maybe...??u need to tune it at the shop...
just a wild guess...

checking ur timing. Get a reliable mechanic to get it tuned.

If the problem still not solved... start to look into possibility for a faulty stepper motor.

Idle Control Valve sensor

Or a faulty TPS sensor. Trottle position sensor

Mitsubishi motor TPS tend be become faulty easily. You can saty it's faulty especially when idiling, u hit rpm till 3k release it and the engine goes dead or almost dead. That u can conclude that it's faulty TPS sensor.
