P0300

i cleared it (CEL) earlier today, did not return, after driving (without issue) about 20 miles or so. Yet im worried at some point it might happen again, i just feel like i didnt do anything really, but only time will tell.

i had a similar issue, had a blinking cel and random miss fire code. It was intermittent issue and it nvr changed the drivability so i thought no big deal. then it crapped on me and had to gimp it home. changed the coils and now it runs great, and has been for a couple K miles. they were $35 bucks each at auto zone and we need two. easy to change, just do it if you havent already.
just my .02.
 
I have had a CEL and code P0300 pop up a couple times in the manner the OP mentioned, the local Mazda service rep says its most likely the EGR. The EGR is still covered under warranty if the car is less than 7 years old (in Canada at least). If I pay the diagnostic fee they will scan the car, if it turns out to be the EGR they will replace it for free and they will reimburse the diagnostic fee.

Will post the results once it has been scanned.

I just had this code. $1600+ later, a couple of days on the road and it's doing the same thing. Car is stumbling with no power. Car is at the dealer again, hoping they don't charge me again for the same problem.
