[Shotimes] cylinder test

[Paul L Fisher]

No, he is talking about the cylinder balance test. Basically, after the KOER
test is complete, you goose it again like for the goose test and then it
turns off one injector at a time and monitors the RPM drop. If it doesn't
drop enough, it marks that cylinder as 'weak'.

The "goose" test is where you floor the pedal just for a second during part 
of the test.  This tests the knock sensor to see if it is returning a 
signal.  At the end of the KOER test, any new codes along with the stored 
codes will be displayed twice.  After the last code is displayed, just touch

and release the throttle slightly and the cylinder balance test should 
kick-in.  You will see the rpm's jump up to 2000 and hold there, then after 
a short time, each cylinder's injector will be cut out, then cut back in one

at a time.  You should be able to see and feel the missing cylinder when it 
cuts the injector out.  The cylinder balance test can only be run one time 
for each KOER test sequence.  If you need to run the cylinder balance test 
again, the whole KOER test must be restarted.
