i have had a few people tell me that it has some thing to do with fuel/fuel system like dirty injectors

Likely fuel or spark issues. Tap the injectors when the car is idling with a metal screwdriver.
Pull each spark plug wire out 1 at a time and see if they all make a difference, if you find 1 or 2 that don't make a difference, tap those injectors first.
