I have a 2010 Dodge Avenger Express 2.4L 4 cylinder. I have been trying to figure out piece by piece why it is popping code P0300 and it would blink Check Engine light. I changed the spark plugs, crankshaft position sensor and cleaned fuel injectors. When I cleaned the fuel injectors the check engine light would come on, blink then disappear. The engine light only comes on after 3000rpms. I’m confused and need help please!
What makes this problem better or worse?
Revving the engine. Anything past 3000 rpms

Hello, how were the fuel injectors cleaned?
Have you performed base engine compression testing to see if maybe there is a loss of internal engine compression pressure on one or more cylinders? Have you replaced the ignition coils? Is the only code a P0300, or do you get some other codes also?
Blinking check engine light indicates an active misfire, so definitely focus on the compression and possible coil concerns -- although with the 'cleaning of the fuel injectors' I'm a little concern of possible damage there.
