My experience with engine misfires on OBDII systems is that the monitors for such events are quite sensitive. The threshold for a misfire is frequently below the driver's ability to feel the event. But there are a few true random misfires that can elude capture. By definition almost always of no concern. And always _extremely_ difficult to isolate _IF_ there is a remedy.
A few years back HONDA was "caught" desensitizing misfire monitors and had to pay a heavy fine. I doubt they have attempted anything remotely similar to mask an Insight misfire "problem."
