I did the same thing with my car and the misfire ended being a burnt valve. I had used BG 44K after replacing injectors, plugs and coils and it worked for about a month or so and the CEL came back again and ran worse than ever. I hope for your sake the 44K is a permanent solution because a burnt valve is a friggin' large expense.
