Ok here it is .My front cylinder in the front left is loading up plugs and missfirring at idle ,But when i go riding around it cleans up .
1. changed coils
2. changed injectors
3. check compression good 160lb
This problem is only in this one cylinder not really sure what it is .The other 7 plugs look great .Also no check engine light.

 

You didn't replace that spark plug? Try it.
