ok here you go. been spending lots of time researching this and finally found the culprit for my car. could be different for yours though.

heres the list of causes:
-Faulty spark plug or wire
-Faulty coil (pack)
-Faulty (front) oxygen sensor
-Faulty fuel injector
-Burned exhaust valve
-Faulty catalytic converter
-Running out of fuel
-Poor compression
-Defective computer

my problem was bad front 02 sensor, but not so common. start with the easy things like plugs and wires, injectors etc.
