Hi All,
You remove the injectors yourself, take them to a "Cleaning Specialist" and he/she does what?

Ultrasonically clean them?

With water and detregent?

Just out of curiosity, can buy an Ultrasonic Cleaner on Ebay for $75 AUD and do it yourself, right?

Gimme your ideas or trials..

Thanks.

I've have used the 'on car' Carbon Clean system where they disconnect your fuel line and run you car on the cleaning machine. I did not find this method very effective.
I have removed them myself and had them cleaned off line. This is a ultrasonic cleaner however it cleans and sprays the injector using a series of pulses to simulate the injector in normal use. This way they can check the spray pattern. I have found this to be the most effective cleaning method.
