On new years I noticed a bit of a stutter under hard acceleration in 3rd and 4th gear. No lights were on so I thought it may have been tire spin. A few days later I went out to start it, and the CEL came on. The car started shaking and the CEL begun flashing so I shut it off and got a ride with a friend to dinner. Went back out the next day and started it back up. Ran a little rough but no more flashing light or shaking. CEL was still on but solid. Drove it straight to O'Reilly and got it scanned.
It threw P0300 P0301 and P0303.
I replaced plugs and coil packs as I planned on doing it soon anyways, but it didn't change anything.
Still throwing the same codes and stutters hard over 3.5k rpm.
Also noticed a bit of a whistle at low rpm in first and second.
Anyone had this problem or know what could be causing it?
