I am throwing codes like no tommorrow.
I went and replaced the plugs, the plug wires, and the oxygen sensor that was blown. but still I am throwing a code that says misc. misfire. any info. would be greatly appreciated.
thanks

Be sure to also have your fuel injectors cleaned up good. Anything that could clog the injector will throw a random misfire at ya.

 

Did you replace them with OEM plugs or NGK's or what? Sometimes having the incorrect plugs will cause this code to appear. Also check or replace your fuel filter.

 

i know its far but you can always use my efilive setup and go log some data, it opens your eyes to whats really going on. might look in the southern section for someone closer, but its realy obvious if you got a cylinder misfiring or something with the 8 cylinder logging misfire count&history.

unless you just put a cam in or something, then those codes are normal.
