Re: rough/surging idle
Irratic idle can be caused by plugs, vacuum leaks, and dying o2 sensors. 02 sensors typically throw check engine lights...take the car to autozone and have them run the ECU for free to see if there are any codes stored.
Also turn the car on, let it idle at warm temps, and pop the hood, listen for air escaping from vacuum leaks.
And how long ago did you replace your spark plugs?

Your 1996 Mitsubishi 3000GT VR-4 is the 92nd out of the 315 that were made that year. Only 21 of which are exactly identical.
