it sounds and appears to immediately run lean when put in reverse and it dies. when you are driving it feels like a miss at certain points when it is in overdrive it bucks sometimes

 

Any codes? Sometimes, those are signs of a dying crank sensor.

 

no codes at all it shifts great in every gear but sometimes buck jumps like a intermittent miss in od but it has zero codes

 

sometimes it will go in reverse at exact idle but if you give it any throttle at all it seems like it starts running very lean and immediately dies. when you put it in park or neutral it starts back up but you have the smell of raw gas and smoke for a couple of seconds

 

it is a 99 5.9 4x4

 

Does it always die in reverse? Does it stumble first, then die? Or is it like you just shut off the key?

Wonder if the shift linkage is pushing around a harness, or some such.

 

 

 

How old is the crank sensor?
