HELP HELP HELP code p300 an p301 misfire in cylinder one I've changed all spark plugs and changed the coil pack for cylinder one and still have the misfire just not as bad I need help from someone who knows what they're talking about

 

When does the misfire happen? Under heavy acceleration only?

Did you check the gap on the spark plugs? I believe it's supposed to be 0.032

 

It happens at idle it was pretty bad until i replaced the plugs an coils i put some seafoam in to clean the jets a little bit and it still happens during acceleration

 

Maybe fuel injector?
