Had this on my V6, there is a re-flash for it, sometimes they have to clean the intakes.
You could try a good fuel cleaner that removes water also.

What do you mean by reflash?

Same here cylinder 4 misfire, and multiple cylinder misfire code. Car has 67,000 miles and its gone stock, I wouldn't think its spark plug related becuase they are due at 100,000. Car was sitting for 8 days, after being started CEL came on. Don't really have money to go to the dealer after 8 days in Vegas...

Mine had a P0300 but pending only, flashed while at a stop light for a few seconds but when I restarted the car it never happened again. Could be a few different things, my compression was good so I swapped the coil and plug to see what it was if and when it happens again.
