I had my S2000 injectors cleaned by a fuel injection shop I have locally in my town, and the spray pattern was poor on most of them. We cleaned them up and reinstalled them in the car and never had misfire issues after that , I started using Redline fuel injector cleaner after that as a maintenance dose, and never had an issue in 10 years after that. The best fuel cleaning products use PEA, Redline, Techron, BG, even Shell V-power and other high end fuels. I think it is cheap maintenance, one bottle of my preferred cleaner treated two tanks and I used one bottle a year, cheap in my books.
