Any idea?
I get this issue when revving at 5000RPM+

more prone to happen during cold weather. I can redline it in the higher gears, but taking off aggressively in first gear for example causes the light to go on as soon as i upshift.

when you restart the car, does it run fine, and does the CEL remain on?

it could be so many different things. most likely spark plugs or coil packs which is what i am suspected for my car. what mileage are you at? you will need to get your car scanned to find out.
