I have a 1991 Ford LTD Crown Victoria with a 5.0 V8 that will not idle. It will only run if I press on the accelerator right after it starts to keep it at a higher RPM. Seems to run fine at a higher RPM. When I let up on the accelerator, it goes to a very slow idle and runs rough, like it's missing, and then it stalls. There's no "check engine" warning light. I'd like to get it to idle temporarily so I can move it to a loaction where I can work on it. Will turning the throttle plate adjusting screw raise the idle a bit? What might be the source of the problem - spark plugs, bypass air value, EGR valve??? Thanks!
