Getting a PO606 code on hard launch, basically 0 pedal to 100% pedal. In between seems to be fine. Seems to happen more after the car has warmed up, but comes and goes and has happened at idle with no throttle. When code appears, the car goes into limp mode. You can clear and drive again. This does not happen on every hard launch though. E38 ecm, 4l80e. I did modify the Throttle MAP, but have put it back to stock. Any thoughts?
