i cant get nissan data scan to connect with my ecu for some reason but this program ecutalk does connect. I have real bad hesitation at wot almost none. So the faulty fuel injector has nothing to do with the vacuum pressure?
whats the difference between a boost leak tester and a smoke tester? I made a air intake plug with a 3" pvc cap and a valve stem. I smoke tested it thru the balance tube and i did not have the throttle body's open when I did it.
