Unfortunately the old Magna was known to suffer from idle shake when stationary and in gear, and there's not a lot you can do to get rid of it. Owners often put it into neutral to overcome it instead of leaving it in gear at traffic lights etc. As for the hunting in gear you could check the throttle position sensor and make sure that is adjusted correctly.

THAT figure is too high. Mitsubishi expert Des Seaton suggests you check the temperature sensor and the oxygen sensors. If the sensors are malfunctioning it could mean the computer is supplying too much fuel.

I WOULD first check the temperature sender, which tells the computer to keep the fuel injectors open a little longer during the cold running phase. The sender could be faulty, though you would normally experience some stalling and poor running if that is the case. The other possibility is that the catalytic converter is partly blocked, which can affect performance, and it's more noticeable when the engine is cold.
