It would never drop below 12 volts so I never thought much of it until this test.
Replaced it with a new battery and after a test drive the voltage is reading 12.9 and not dropping. Roughly 1 volt makes all the difference in the world after factoring in the resistance of the wires.

So it idles 100% consistently now?

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
