      the car is running lean which means not enough fuel is getting through, or too much air is getting to the system, does it run lumpy or is it just a misfire? have you tried swapping air mass sensors with a similar model theses tend to give a car a lumpy mis fire feel as they arnt giving the right signal to the ecu to put the correct amount of fuel in.

      hope this helps buddy
