Limp Stillen Supercharger dtc p1239

wymoteeZ

It's been on the car four months, 3000 miles. I did the 1st SC oil change 500 miles ago. I would say, yes, to the coasting part. It does seem to glitch when rolling under no load. Even an accelerator pedal release to slow on the freeway.
Also, I took it to redline in 3rd gear yesterday at WOT, & noticed power surging every second or so from 5000 rpm up. If that means something. At least I have ruled out the Bank 2 Throttle Body, and any component built into it. Maybe that just leaves the Accel Pedal assembly ? not sure. To be honest, I don't even own an ohm meter. That will be my next purchase. Then I can properly go through the Nissan Service Manual Diagnosis for dtc P1239.
