Don't know if this is old news or not, but I've turned up a mistake in the pre-78 service manuals pertaining to the resistance readings from the air and water temperature sensors (Pages EF-52+53 for 1976 and Pages EF-53+54 for 1977). Similar mistakes are in the FI "Bible" as well. Apparently there was some difficulty translating from degreesC to degreesF. Add a language translation to that, as well as a positive to negative conversion complication, and you've got issues.

To start, here's the 78 air temp sensor chart as a reference. The math works out as do the thermister resistances:

But in the previous years, the temp vs resistance charts are wrong. Here's air temp:

And here's the water temp sensor on the next page:

Similar mistakes in the Fuel Injection "Bible". Here's the air temp sensor test:

And here's the water temp sensor test:
