Why is it stalling?
My 1997 Aspire is idling rough and stalls when I take my foot of the gas. I have changed the sparks plugs, plug wires, timing belt, drive belt, distributor cap and rotor, and the air filter. Fuel is pressurized, engine compression is normal for all four cylinders, PCV valve is fine, and the plug wires are in the correct order. I don't think it is a vacuum problem, because the engine runs much better if at least one spark plug wire is unplugged. I'm stumped

Re: Why is it stalling?
Welcome to AF!
Have you replaced the PCV valve? Checked it's hoses for leaks? I think you need a new IAC (Idle Air Control) valve. It should be on top of the throttle body. It is a small electrical motor with a couple wires going into it. Take it off, clean it with carb spray and then lubricate the pintel with a couple drops of oil. If this doesn't take care of the problem you probably will have to get a new one. They aren't cheap.
