So what is the solution here guys? My car will run flawlessly below 3000 rpm.
The minute I begin to drive it spiritedly the car goes into that "limp mode" losing power. Once I turn off the engine and start it back up, the car performs normally once again under the roughly 3000 rpm.

The check engine light began to flash and gave me the following codes:

P0301
P0306
P0304
P0303
P0305
P0302

Essentially every cylinder misfired. But the car continues to run fine. I want to be able to drive my car above 3000 rpm.

Any thoughts?
