you may want to check the throttle position sensor with a ohm meter also check the map sensor and o2 sensor those are the main sensors that control fuel air mixture. if all those are good check the temp sensor on the air intake hose and maf sensor if equiped with one

try to pull codes from the computer if you can they can tell you alot about what is going on with the car also

hope this helps Cool
