I want to get my injectors cleaned...I have heard of different types of methods...fuel rail flush type and actually taking the injectors out and washing them with an ultrasonic cleaner...I would also like to know who is highly recommended in Sydney... I still have this lingering idle problem even after changing plugs, 02 sensor, cleaning throttle body...so im going down the path of cleaning injectors and changing fuel filter to try and solve this rough idle problem... Any input is appreciated...
