runs fine in park or at idle. go to put the truck in gear and it stalls out, will not take a load under power. I am thinking vacuum advance here, or the pcv egr or tranny vacuum regulator. guess I have a big morning coming my way. just don't know what to purchase first. Replaced some cracked old vacuum line, got two miles from home, did it again. Had to abandon truck and walk home with dog.
