What do you guys get in the way of missfires

I always seem to get a few. usually between 1 and 7 here and there, and often zero for a good bit. I've changed plugs and coils and confirmed gap .032. Do you guys see a few here and there or sit on mostly zero?

I get a few random misfires, never really look into it unless they're misfires at idle or WOT

I'll get one or two here and there, but it's always at the most random of times. Not enough to even feel it, but you can see it in the misfire history on a scan tool

a few at cold start but always single digits. Most likely false knock.

'm going with the false knock theory. It's random and cant be felt. I am going to check history though and see if it's isolated to one cyl, then swap the coil/plug and check again.

You can probably bring your gap down a little more 28 or 30 I was told by someone and what plugs are you running ?

0.032 shouldn't cause random misfire issues.
