As expected… bad fuel injector is the culprit!

Cylinder #4 was misfiring and cylinder #1 had no misfires. Swapped the injectors between the two and voila. The weird thing is that in between swapping the injectors, I tested it with the carb cleaner method and it seemed to spray normally and it wasn’t leaking… weird.

Now I’ll be looking to get these injectors cleaned since I cannot replace them. I don’t see a 600cc Denso option on the market for the 370z which is what came with my GTM Stage 1 kit.
