Did you trying using the search and typing P0302? Much can be learned that way.

Just did a quick search (as I suggested) and found a thread titled "Solved the P0302"
This one might be a good read for you.

I was having the same code after the dealer replacesd the coils and spark plugs but first it'd only start blinking @ 5k or 6k RPMS then remained on all the time. try to reset it with the brake pedal technique and didn't work so i disconnected the battery and never came back on.

is it right what i did? or should've i taken back to the dealer? it's under warranty anyway

You did good but FYI the Brake Pedal dance does not reset CEL codes it just resets the Eccentric Drive shaft.

The "brake pedal dance" resets the KAM which contains the sensor profiles. This will clear the CEL... but it will come back if the "issue" isn't corrected.

If you're still getting blinking then they did not resolve the problem. The ECU is detecting a misfire in upper RPM's on your #2 rotor. The resolution is either the replacement of the spark plugs (the typical resolution) or the replacement of the coil packs.

I have had this problem all week and replaced my plugs last night. Sure enough the leading plug on my #2 rotor had NO electrode left! I replaced all 4 just for the hell of it and now the car is running like a champ. Took around an hour and a half to do I think, and I'm far from fast when working on my car.

As far as getting rid of the CEL goes, I just unhooked my negative battery cable whie working on the car. Leaving it unhooked for a while will reset the ECU and get rid of the CEL.

I'm not CEL-free and my car is running like a champ.
