Mis-fire of sorts

[zieg85]

Just out of curiosity, what scan tool did you use? Make and model?

Does it have a misfire monitor, can you get mode $06 data?, can you take a snapshot of your data when it occurs?

The scan tool does have a misfire monitor but not sure on the mode $06 data.  I'll read the book and see if I can actually learn how to use it other that just plug it in a get the codes.

That looks like a decent code reading tool. I used to have one similar from Matco. I have a newer model now, it does full diagnostics for all makes and models, it does pretty much everything except have bi-directional control. If you can view a miss fire graphic or data that would be a huge help in determining whether you have any issues or not.
