Car misfire once or twice a week
My 07 Fit misfires maybe once or twice a week randomly, but only while stopped at red lights. It will misfire once and then not again for a week or so. I'm not too concerned but I'm curious as to what is going on and why it only misfires on occasion while stopped.

Bear in mind that a weak spark will not 'set' any CEL codes. But it still results in a poor spark, and incomplete combustion, which you might not notice from the driver's seat.
The Holy Trinity of Fit misfire remedies:
1. Replace sparkplugs (new Iridiums)
2. Replace coils all at once (Hitachi part # ending in 053)
3. Adjust valve clearances (loose end of spec on exhausts)
