Took the plugs out

[Auss15]

Took the plugs out to have a look at how they're running. Interesting result. It appears 1&4 cylinders are running rich, 2 a little leaner and 3 definatly lean.
What do you think? Need to have my tune checked? If I do I think I need a new tuner

Find it weird that some plugs are covered in fuel and others are not getting that nice bownish deposit which is the norm?

Would this suggest possible coilpack issue if some cyclinders are burning different to others??

Hmm, strange. 1, 2 and 4 look fairly normal to me, it's strange how 3 appears to be running leaner. What injectors are you running? Perhaps #3 injector is not performing as it should be?

Thats what I'm thinking,I'm going to have them taken out and flow tested. I might have a lazy injector. I'm running Nismo 555's
