car should be on or running. Otherwise. whats the point in checking how open the throttle is?
well if you read the top post it say's WITH THE IGNITION OFF CHECK THE TPS,thats a little misleading,

Check step #7......

7. With Ign On Eng Off, check TPS voltage output....if it's between .8vdc - 1.0vdc, it's OK. This voltage check should be done between the Green and Black wires at the TPS side connector as shown in the pic below....(-) terminal of the DVOM on the Black wire and (+) terminal on the Green wire.

One little detail I wanted to add to this procedure. DO NOT rely on the stock tachometer to set the base idle speed. The pictures below are of the same 5.0L engine with a B-303 cam (a hack installation done elsewhere By The Way.... stock heads, valve springs, rocker arms, etc... Dissapointed ), idling with the IAC disconnected while I was setting the base idle. The first picture is what the owner will always see (sometimes higher) in the instrument panel and the second picture is what the real idle speed was. As you will see, there's a 350 RPM difference (1,000 RPM at the instrument panel vs 650 RPM at the trusty Tach-Dwell-Voltage meter).

So if we don't have a cool device like that to check the correct rpm do we just set it as low as possible?  I wonder if sears still has something like that?

You can find volt meters to do the same thing as well as some timing lights..

While your waiting you could probably get away by doing it by ear and feel.
