OBD Code P0304
99 Rodeo, had engine code read and it came up P0304, cylinder 4 misfire. Question. Should I start with the plugs/wires first? Buddy says it's "all oxygen sensors." What is the best way to proceed?

Re: OBD Code P0304
If you have over 50k on the plugs then yes replace them (search the board for more info, Isuzu's only like certain brands).
No wires to replace. You could also, switch the coils around to see if the misfire moves to a different cyclinder. If so you have a bad coil If non of this helps: One common cause for a misfire code is due to a leaking intake manifold gasket. (see the FAQ's).
