Message Not sure how you count them, but it's the cylinder at the nose of the car, on the driver side. (Number 2?). I THINK it's not firing.

When I unplug the coilpack connector, no drop in RPM's. When I listen with my stethoscope (luckily had one since I'm a paramedic), I don't hear the definitive "Thwack", I do on the fuel injectors.

What I Haven't done yet is check compression, but is it necessary at this point? Or are these 2 things alone enough to say yes, it's the injector.

It still has all stock injectors and at 105k miles, I'm guessing that's the culprit.

Another odd fact...I'm still getting good boost with the dead cylinder, and no detonation, which I find odd. Maybe I just haven't run with all 6 cylinders going in so long I forgot what it feels like...very possible.

Just looking for opinions from those more educated than myself in the Z world. Thank you again.
