i couldnt find anything on this but here is how it goes. i was driving to school today and my truck instantly cut power while i was driving. when this happened the truck slowed down and would pop through the intake if i tried to accelerate. i did manage to floor it and it would only accelerate to 3000 rpm or less max but it would hold a steady rpm and speed when floored maybe 40 mph. now the kicker, if i put it into neutral and turned the truck off and back on it would be fine again for a few minutes until it instantly lost power again. it feels like someone just flicks a switch. is this some kind of limp mode? i think my 1227747 ecm has limp mode. i dont want to be stuck somewhere and have barely any power. what could this be.
