It’s definitely drilled thru, looks like teeth were drilled thru on the corners and the edges were chipped off. Gonna have to look into swapping the tone ring.

yeah... damage to the tone ring causes false/unstable signals.

Whatever complete idiot, that drilled it out, without dropping the pan and protecting the tone ring should be contributing towards the tone rings replacement.... which is NOT going to be easy to do by any means.

Would this fault still happen while I’m idling? I just got to my truck, and before on the old ecm and harness the truck would have erratic rpm’s if I stepped on the pedal over 15k rpms that’s where the truck would start to have erratic rpms. Right now it is no longer doing that, after swapping ecm and engine harness. I can step on the pedal and keep on it without the truck having any issues, however I have yet to try it on the road.
