How to identify injector flow problems (Toyota 1.8L) part 2

This is a 2003 Pontiac Vibe with a 1.8L Toyota engine. The customer replaced the spark plugs, ignition coils, MAF sensor and other components in an unsuccessful attempt at fixing this misfire. I decided this would make a great case study for my class at Rosedale Technical College and for you, my YouTube students! In this video I am showing how to do a fuel injector cleaning service in an attempt to fix the injector flow problems revealed in part 1. I was unsuccessful in this case and from my experience, injector replacement is the only fix for these types of issues.
