Major 7.3 Headscratcher

Ya sucks ass

anything ever get solved on this? I just joined looking for info on another problem but this got me courious, I do know that when you unplug the IPR the engine goes into default, it stops looking at other engine sensors and does what it think it needs to do, this makes me think that there is a problem with another sensor, Cam, MAP, or something like that.

Not the IPR, the ICP sensor.

Did this ever get resolved?

7.3 headache

Also wondering if this ever got solved. Have a very very similar issue.

I wonder if tone ring is wobbling.

wonder if the pigtail the first mechanic spliced into the ICP was mis-wired..
