02' Boxster Blinking CEL

[Steelepuls]

My 01S did this recently, also in cold rainy conditions. I believe it was about <37 degrees F out when I saw the blinking CEL. Luckily I was only a mile or two away from home, engine was not even warm, so I brought it back to the house. Left it until I had time to check the codes, which was P0300, random multiple misfire detected. The blinking CEL only lasted about a minute or so, and then went away before i got home. I cleared the codes and have been driving it for about a month in warmer weather, above 40 degrees F. No blinking CEL and running just fine.
