Contour Enthusiasts Group Archives Forums Modifications Duratec Maintenance How to Clean Injectors? (already read the How-To)

Hi,

i've already read the 'how to clean intake' article, and plan on doing it, but my question is how to clean the inside of the injectors? Should I just let them soak in B12 overnight? Or is there a 'fuel injector' specific cleaner I can use? My reason for doing this is because I have the famous P0171&P0174 codes. I read somewhere that cleaning the injectors will get rid of the codes. Thanks for your help!
