This was an injector I installed like 6 months ago from Coz using the 740cc adapter kit. I've installed plenty of injectors before so I was pretty sure the o-rings were not pinched. I knew the spark plug was firing outside the cylinder, but not inside. Plumes of smoke was coming out the exhaust and in fact it seemed like some of the fuel was in the drivers side exhaust manifold smoking...I mean it was definitely smoking in the engine bay, just not sure where. So I was super confused that spark was there and fuel was there, but the cylinder was missing and my spark plug kept coming out drenched in fuel.
