Thanks a million!
However.... one question for Oakos Automotive:
You wrote that the test should be performed at 350rpms, WOT... how do you insure that the criteria is met?
All Spark plugs removed, Fuel and ignition disabled, and throttle open full. Crank the starter over until the gauge does not read higher. 350 RPM is the RPM you will get in this config.
