so I've got a persistent 3500 limp mode.

I've reset the ECU via pedal dance and via battery disconnect.

I replaced both the camshaft pos sensor and the oil temp sensor.

the Z is now at the dealer who will diagnose why im in limp mode (hopefully)

the plan is for them to tell me why shes in limp, then I'll grab the z back and swap out what ever sensors are crapping out or clean the MAFs etc. we'll see how that goes.

It might be plugs from all my fuel starve or a bad sensor or O2 sensor?? who knows. Hopefully I can get my high speed grocery getter back on her feet before the snow starts falling and I have to park her in the shop till spring!

She ran well for 2 track days this year so no complaints, but its frustrating when you can't get get you street mods running right and reliably. There are so many inputs to the ECU that can cause limp mode that I think (?????) the dealer diagnostic tool might be the best way to get to the bottom of my issue? stay tuned. I'll let you know how they do. (I'm cringing as I type that)
