Hey guys i have a lnf cobalt ss with a e69 pcm and when I use the scanner to log my cold starts I noticed that sometimes it will read misfire current cylinder 4 and do a count however it doesn't populate in the misfire history cylinder 4. After a bit my current misfire will go to 0 and nothing changes for history. Does this mean that the PCM is not registering the event or that it doesnt believe it is a true misfire?


How can I be certain that it is indeed misfiring?
