The ngk 11b recommended by z1. I checked the o rings n all r fine. The car keeps flooding as if the injectors r staying open. Car ran perfect before injector replacement. I ask did the plenum water hose bypass, deleted egr n installed gt675 at the same time. But the problem im having is definitely fuel, i feel like z1 send me the wrong chip. When i insert my previous z1 chip(stage3) for stock injector size, the cat does the samething
