These are the things that may cause a misfire so I wouldn’t say it’s an injector or valve spring unless they test….
- Plug
- Wire
- Coil Pack
- Coil Pack wiring
- Fuel Injector
- Fuel Injector wiring
- Fuel Injector wiring- bad ECM/PCM
- Valve Spring broken
- Burned Valve
- Cam Lobe worn
- Low Compression- Rings

Do you have longtubes?
I had the same issue. Was throwing codes intermittent misfire as well as traction control / stability.
ended up being a fried 02 sensor wire. It was laying against the exhaust and burnt through causing a bad misfire.
