Was reading in Ohms. The lower resistance readings were from the warmer
car, but only by about 1 hour. Both had more than 3 hours of cooling
time. After sending the original email, a 30-0-30 ammeter was found and
that test was used. On the CD, the current draw dropped to 15A quickly
(1-3s) and 2-5s later the current was around 10A. To see what a good (1.5
years old gp) plug did...it would hit 20A and slowly over 6-8s drop to 15A
and stay there. I'm ordering 10 gp's tomorrow.

The resistance of the good plugs should be identical (+/- 10%) IF the
plugs are at the same temperature. If one engine has not been run in 6+
hours and the other car's engine has been recently shut off, the plugs
in the engine that's recently been shut down will read somewhat higher
(maybe 20-30%).
What the heck units of measure are you using? Good plugs should read 0.6
OHMS cold!!
