DBW Throttle Stops working At WOT - Reboot Required
Just wondering if anyone has seen this issue where the throttle becomes unresponsive on an LM4 (trailblazer) in WOT. Accelerator automatically drops to 0 and no longer responds until restarted. Also seeing that the mass airflow drops to zero while MAF hz appear normal. Any ideas as to how to prevent this WOT cut out? Issue occurs at 3:07:11 pm, 14:31 minutes in to logging. I have attached a screen shot showing the Mass Airflow of 0, scan file, config. Codes are P0068 and P0101 see attachment for further details. Mass Airflow sensor and pedal are new based on factory specs. Throttle body is the original that came from the junk yard. Didn't grab tps position this time but will have it in the future. New cam 212/218 lsa 114 with .550 lift. I have done some MAF air flow tuning but could do some more above 9000 Hz. Currently swapped vehicle is hiding out in the garage until spring and the salt is gone from the winter roads.
