AS a follow up, my mechanic went through each of the items you recommended. He replaced Mass Air flow sensor, checked for proper fuel pressure, all vacuum pressures checked, etc.
Still the light comes on, not all the time, but occassionally. The trim goes up, then down, depending on how long the engine is run.
He was checking to see if there is apossibility th e problem lies in the computer being reprogrammed wrong, or possibly the chip being replaced.
Any other ideas where I should turn? He thinks I may have to go to a Mitsubishi Dealer and have their mechanic check everything. I was hoping to avoid that.
