Question type: Maintenance & Repair

I was raving my engine to 2000 rpm
trying to warm my car up because it
was freezing outside. While running it
at 2000 rpm check engine light came
on. Grabbed codes which were,
P0300
P0304
P0305
P0306
Cylinder 4,5 and 6 misfires and random
misfired.

I changed plugs, coil pack and could.
Then reset code. Week later same

warm my car at 2000 rpm. Light came
on again. Has 6 cylinder engine 4.0L
