Hello cstemm, I just ran this test the other day. You can find information about the EEC IV on many websites which includes running the normal KOEO, KOER, and Cylinder balance tests. The balance test must be performed after running the other two tests and correcting any errors you find.
i thought you had to breifly hit wide open throttle after other tests complete but i never tried it and its been a while since i read it so i could be wrong
rlong - that is correct. It will then shutdown ignition spark and fuel delivery to one cylinder at a time until all 6 cylinders have been tested. It looks for cylinders that cause excessive RPM drop when shutdown.
