You could do cold, but will get codes saying temp sensors out of range. Do again warm, or skip cold altogether. Then do koer. Be aware it takes a little time to get the cylinder balance codes after entering that mode (wot press after koer codes are done).
KOEO, turn reader on, turn key to run (don’t start), press test on reader. wait for codes.
I forget the exact preceedure for KOER, but I think you do the same except start engine then press test. After codes are read if you want to do a cylinder balance test, you do 1 quick wot press to enter that mode. Then wait.
It’s all in the manual.
You gotta have tough skin to hang here. Ease up on the attitude and don’t take anything personally...keep on topic. The help will come if you let it. Hang in there.
