I don't think that'* weird at all. I had a few little funny problems like this when mine was failing. Including a misfire due to undervoltage on a weak coil. It improved dramatically with the new alternator, then the new coils cleaned the rest of it up.
A good voltage check would be in order. From the battery before you start the car, and idle charge as well.
