My next option is to replace all the spark plugs and wires, but anyone who has worked on these know it is no easy task to get at the plugs in the back. I started it up again this morning and it was making a loud knocking sound shut it off and let it sit for 15 minutes. Restarted it and NO SOUND running fine. Does this sound like a timing issue? Dont think you can adjust timing can you? Is there a sensor somewhere that controls timing? Any help is appreciated.

A lot more info needed?
Code P0300 only tells you it has a engine miss.
Clear code and see if it returns.
Is today the only time it has made a knocking sound?
Wat is tune up history?
Tips on getting a good answer to your questions.
People trying to answer your question do not have a crystal ball.
So give them all of the info you have like year make and model and engine and transmission and mileage.
Also cars engine and transmission service history or any recent repairs or problems.
Also a description of your problem and what it is doing or not doing.
If you have codes give up the code no.
And remember a code does not say replace the part but only points to the problem that you have to check out.
So to better help you give up all of the info you have on it.
