I celebrated PHX's new found rain a couple of weeks back and now my '74 Jimmy has been wanting to stall once it gets out of the garage. I have tightened down the carb, changed the PCV, air filter, plug wires, and have now gotten to the EGR valve. I have not been able to find any diagrams showing where the vaccum line goes to on it. Does it just hang out? My experience tells me no but I am not seeing anything to indicate otherwise. I gootta trip to Mexico hinging on this.
