What is the cause of 1995 V6 3.0 engine Nissan PU running rough & dying upon deacceleration for stop light?

I have changed plugs, fuel filter %26amp; air cleaner. I am wondering if it is the Oxygen sensor. It seems to smooth out when accelerating. Would a bad or dirty fuel injector cause something like this?What is the cause of 1995 V6 3.0 engine Nissan PU running rough %26amp; dying upon deacceleration for stop light?first off as you know you don't have carburetor,,,and as for the dieing problem,,yes an oxygen sensor will cause this what it does is tell the computer the car is running to rich,,so it starves it for gas,,this is what causes the problem,,as for driving it,,it will smooth out as long as your driving it,,because the sensor cools off some,,it works by temperature and when it goes bad it gives a high temp reading,,this may not be all that's causing it,,but i would certainly replace it first,,especially if it has not been replaced in a while,it cant hurt anything,,i own a repair shop,,and when i get one doing this,,and i scan it with the computer,,it usually is the oxygen sensor,,be care full putting the new one on,,they break pretty easy,,good luck with it,,maybe this will help you.

I doubt its your fuel injector i think its your idle try turning up your idle and see what that does for you!

could be carborator... dirty fuel injector might it to because at an idle it get rough and starts to die but when you press the gas it goes again so you're forcing the gas through. i had a car the wouldn't idle unless you held the gas pedel, had to have the carb rebuilt and changed out the fuel filters and it ran fine after
i had same problem timing belt was replaced. it ran and performed real good.
do you smell gas? could be oxygen sensor...could be idle control valve
