Dreaded p0300
So im only getting 1 code p0300 its misfiring and running kind of rough at idle. Im in the process of doing new intake gaskets plugs coils and valve cover gaskets but am going to do a compression check. Also have a feeling clogged precats is my problem but any input is appreciated to help with this code thanks

First way to diagnosis then work up to spark plugs.
Last repairs I did lead to one bad coli.
