With the key on and the engine off I get the following:
flicker of the check engine light (shows the continous codes right?)
3 (or maybe its 111?)

The numbers mean the test passes, but you didn't read the directions.

The KOEO codes are 1-1-1 1-1-1 (KOEO test passes)

1 (separator pulse)

1-1-1 1-1-1 (No codes in continuous memory)

The KOER codes are :

"4" -- you have 8 cylinders

"1" -- The operator (YOU!) are supposed to stomp the gas pedal after the "1"

flicker -- high speed codes dumped here, for an electronic scanner to read

Code 538 -> You didn't stomp on the gas when you were supposed to (see above)
Code 536 -> You didn't depress and release the brake during the test (do this any time after the "4")
Code 632 -> You didn't depress and release the O/D cancel switch during the test (do this any time after the "4")

To your credit, you didn't get code "539" like I did (left the A/C on during the KOEO test). I felt really stupid spending an hour trying to track down codes "53" "39" and "95" once I realized what codes I was really getting.

Run the KOER test again. After the "4", depress and release the brake a couple of times, turn the steering wheel left and right 1/4 turn a couple of times, press O/D cancel a couple of times

When the "1" comes out, briefly floor the throttle (known as the "goose test".

You should be rewarded with 1-1-1 1-1-1 (pass) from the KOER test

Thanks for the quick reply. I feel pretty stupid now.... I assumed the KOER test was like the KOEO test, but I was wrong.

Thanks for the help, I'll retest it in the morning.
