Hey I did the DIY KOEO test and Was wondering if someone could help with this if I don't figgure it out...

Turned the key fuel pump went and the thing flashed fast 3 times then it started the codes.
It took it 4 seconds to start the first flash.
After the first flash there was 2 seconds inbetween. Then 5 seconds between the 2nd and 3rd flash. Between the 3rd and 4th flash there was 2 more seconds. Then there was a 10 second pause before another flash. After that it took 6 seconds, 2, and 5 seconds. After the flash from the 5 second pause it took 2 seconds for another flash. After that I waited 30 seconds and had no more flashes.

Here it is after the first flash
2s,5s,2s,10s,6s,2s,5s,2s. S stands for seconds obviously. Could anyone tell me what those mean?

Check the flashing pattern explanation at DIY KOEO/KOER/Cylinder Balance Self-Test.

I looked at it but I'm not really sure on how to read what it says. So that's why I asked hoping someone has done it before and could help. My dad was the one holding the watch and telling me the time it flashed as I wrote it down.

It was 4 seconds after a few rapid flashes before the first flash then 6s,11,s13s,23s,29s,31s,36s, last one was at 38s. That's just using a stop watch so it was 2s,5s,2s,10s,6s,2s,5s,2s. Looking at the thing isn't helping me much.. The 2s,5s,2s,10s ect.. is how long inbetween flashes

Don't concentrate too much on the seconds, just look at the pulse pattern....... for example, a code 23 as a continous code, repeated as a memory code + a code 33 would be.... (using "-" = 1 second pause)

|--|-|--|-|-|--|-|--|-|-|---|---|-|--|-|-|--|-|-|--|-|-|--|-|--|-|-|--|-|-|--|-|-| (the single pulse after code 23 is the "separator code"

Keep in mind that the codes are repeated. Another example is the one for code 327 for SN95 setups (3-digit codes format) = ...... the 2-digit flashing format follows the same pattern as the first two digits of the example pic.

Well if I used the - as a second pause and | for the flash it would be
|--|-----|--|----------|------|--|-----|--|
And the 10 second pause is the pause between codes..I think..Right?
But I'm still lost [&:][>:][&o]

Well... Is it just saying code 25 twice? If that even is one. Or did something possibly go wrong during the test? I did it like 3 times and the results were the same pretty much.

The above would be 11-11-separator-11-11 = System Pass

Would the KOER test possibly show a code saying something was wrong? Cause it runs really rich but it ran alright. Then I hooked up the unhooked main vaccume line and the map sensor vaccume and it wouldn't idle on its own. Now it runs like crap. Could be plugs fowled on that part but that doesn't say why it runs really rich.

Run the KOER and see what shows up, I do suggest you check those spark plugs first though.

I have to get it to where it will run good first! ha but when i do i'm certainly going to. Could you try to explain how decipher the pauses and what not I just don't understand it[:'(]

Actually. I think I got it now. There's 2 seconds between digits and the 4+ seconds between codes. However many times it flashes is the first digit and then after 2 seconds however many times it flases is the second?
