I will be looking into those but the issue is fixed as of today. It was cylinder #2 coil pack, replaced it and it runs perfect in WOT. 11A/F @14.5psi boost I tested the coils resistences but it showed that they were all fine, so I replaced one at a time and drove it after each swap of a coil. Visual...

It's running on 5 cylinders because it's such a bad misfire. I'll be cheacking coil packs today by swaping one at a time and then driving it to see if it still misses.

The very first thing that happens is the RHS Bank of injectors cut, with this the TP load also dies and then Bank 2 and TPS drops to Idle Volts and then everything goes out. The TPS was fine, I stomped the gas and it built boost and sped off and then the Injectors hit this issue and then it all goes...

turning off DTCs just stops the ECU turning on the Check Engine Light. You need to ensure all your sensors are properly connected or stubbed (resistor for knock sensor for example) to the correct setting Neutral switch should be at least off otherwise may affect operations like what you are seeing ...

I'll have to look in to if it's even in the car. It was swapped into my 240sx convertible and I'm not sure it's even there, I can start the car without even pressing the clutch pedal in. Thanks for the heads up. Curious, about the DTC's though is Checked sensing on and Un-check off? I just want to k...

Probably, how do I turn sensing for this off? I know there is the DTC 1-5 section that has check marks next to certain things but is Checked on and Un-checked off? or is it Vise-versa?

I've been diagnosing this issue for a LONG time now. Orignally I was thinking it was a sensor or mechanical part (ignitor, coil etc.) Which I have already tested or changed almost everything. Looking in the timing direction now. My idle is fine at 20* but when cruiseing it's in the 40*'s and under l...
