if your smelling raw fuel then it is running very very rich, you should start by tring to fix that problem could be the reason its miss fireing, to much fuel. as for the knock, is it a loud knock coming from the motor? if so it could be a spun bearing witch is very bad. whatsup with the underglow? kinda ricey but to each his own.
it sounds like an identical problem that my car had. severe misfiring, bogging, running extremely rich, extreme power loss, etc. even threw the same code. i changed my o2 sensors and it continued but when I changed them to Bosch 13111's, the problem went away. kind of an expensive shot in the dark but it really sounds identical to my problem and like i said: even switching out to stock o2's didn't help. i had to go to the 13111's. btw do you have headers and if you do how recently did you install them?
