91 escort only runs when i pump the gas

91 ford esort pony. 1.9 fuel inj. the car stalled and would not start again. it had bad valves so i replaced them. when i got the engine put back together it will only run when i pump the gas pedal. i put a new throttle positioner on, didn't help. ???

My '94 Escort started dying when I came to a stop. Turned out it was the vacuum line feeding the PCV valve, up on the top of the engine. I popped the hood and could hear a faint hissing.

The aboev person was most likely referring to the vacuum elbow that goes bad on all of these cars.

You can see this one is bad, with there being a hole in the back of the elbow:
