Added the valve cleaner today. Put the ******** recommended fuel injector cleaner in four days ago. Still misfires. White smoke and fluttering. Haven't tried loosening the fuel lines yet, but will this afternoon. If the injector is clogged, what's involved in removing the troublesome injector, cleaning the injector and reinstalling; probable need some fuel return line tubing, don't you think? Thanks for the expertise.
