Just after a bit of advice here... I've heard that the best way to clean fuel injectors is to ultrasonically blast them...?
Well it just happens that I regularly use an ultrasonic bath at work, so was planning to have a go myself. Has anyone tried this themselves? Or know how it is usally done (ie. is it a case of immersing the injector in a jar of petrol, and blasting this in the ultrasonic bath...?)
