Also another little trick I have observed, is that if you have the return line from the injectors returning to the fuel tank right next to the intake line coming from
fuel tank , you will get air and bubbles sucked into the intake line and then onto the injectors , and it will sound like it is running on 5 cylinders and you think there is an injector problem when there is not. So these two pipes need to be apart in the fuel tank , and also make sure the fuel tank is at least 1/4 full. It is very surprising how much fuel returns to the tank via the 2mm restrictor and then into your normal fuel line, it is like a garden hose full on ! Cheers Andrew.
