Removing, cleaning and testing CIS injector flow on a vw Mk1 golf gti

Want to see how the CIS metering head works?    • Bosch K-jetronic - Mk2 Golf GTi 16v - Fuel...   What I forgot to say, if you do have to adjust the flow rate between injectors the pump will still push out 100% , when you adjust the 4 screws on the metering head for the injector your just averaging out the injectors to 25% each regardless of time. ie if one cup was more full than the other if you restrict one cup the other 3 will come up in flow rate . Best of luck, the hardest part is pulling the injectors out ———————— Support me Did you enjoy this video ?

Pull all 4 injectors and have 4 of the same bottles and test for both volume and spray patten and non drip. If you remove the air pipe intake off the top of the airbox you can lift the flapper in the air box up. If you can lift it by 2mm over 30 seconds you should get about 8-10 ml of fuel
