I been having issues with a misfire lately on my ls1 i have changed everything dealing with my spark now it comes down to fuel. This is all happening on cylinder 6 has anyone had a issue like this before. Im thinking it might be the injector since it is the only thing i havent replaced

 

run some fuel injector cleaner in it, the injector may be cloged and if that does work i would swap wires and coils from a different cylinder to see if the new parts may be bad
