Engine problem - p0300 - Whats the fix?

If it comes back on, clean the MAF sensors like stated above. I had the same code twice since owning the Z and cleaning the sensors worked both times.

Having this issue right now myself with one difference. I am only getting the random misfire detected and no indication of a specific cylinder. While I am driving I also get my "Service Engine Soon" light flashing at me, then off for a half mile then flashing again. Got home and ran the code and it doesn't specify a cylinder. And advice would be great. Thanks

And have I lost my way, or is one coil pack really $125?

JDHeart.....when this happened to me the light was steady (not blinking). Im not sure but i think a blinking SES light is worse than a steady one.
Someone else that has had their Z longer or knows more about them can probably verify this for us.......
