Re: 90 350 TBI Vacuum Lines

Truck has A/C and heat. Thinking "out loud here":

Clogged EGR passages=distinct possibility. EGR holds a vacuum...causes truck to die if diaphragm is pushed. Wiring...uh, it runs is about all I can say!

When time allows - hopefully within the week, I'm going to try to make sure the vac lines are where they ought to be and working right. As of now, all I can say is "I think they are right". Still - not sure about under the dash since I have that vent door/actuator problem.
