i think it could be but i doubt it, maybe a ground, or a wire of some sort that has come loose, one thing that i would check is the fuel pump shutoff switch(located on the drivers side in your trunk or hatch) i have heard, on rare ocassions, of those going bad, or your fuel pump is just hittin the dirt. also do you have the right calibrated mass air for those injectors, if so what kind? and what else do you have done to the car.
