Does anybody have an updated link to this page?

I'm not a fan of adding off-site pages to the index, for this very reason.

Gonna nuke this sky high unless somebody saves it somehow.

So I was looking for this and ran across a thread on the Corral where one of the members said you cannot use a multimeter to test them. Post in the thread is here:

I did find this over on the Ranger Station but someone smarter than me needs to verify:

Ford EEC-IV/TFI-IV Electronic Engine Control Troubleshooting - The Ranger Station

Is your Ford Ranger / Bronco II is stalling/dying or sputtering when hot but runs when it cools off. This can be caused by a faulty TFI.
