Used today to clean four injectors from my 1996 MGF. One injector was spurting out fuel in a single stream. Quick clean using this kit and a can of carb cleaner (you have to purchase separately) and it's now a nice even 'mist' spray pattern. I watched a couple of YouTube videos on how to use the kit which helped a lot. I used a 12V golf cart battery to power the injector, which worked a treat.
