Default CIS Fuel Injector Cleaning

Hey, the audisexhaust is burning really richand dirty , and it has nothing to do with adjustments.

Popped out some injectors, and seems theyre fairly gunky and have some dirt build up and corrosion inside. This is because fuel coming right before the injectors in the line is fresh and clean, and once it shoots out the injector, its much dirty.

On top of that, one of them is stuck open, i can breathe right in and out of where the valve needle is, and pushing it wont close it. Anyway to fix this in somekind of chemical or better off taking it to a professional? (1 new fuel injector will cost me $100)

All i can really think of is giving them a 24 hour in some kind of bath, acetone, fuel injector cleaner, brake cleaner?

Any ideas?????

Its also not even spraying a mist, but instead its just shooting out like a water pistol.

the build of the injector is really simple inside ... a ball and a spring ... so if the spring is broke cleaning will not help ... look here and bookmark this site http://www.sjmautotechnik.com/troubl...or.html#inject this guy is and audi guru .... and new injectors from www.blauparts.com were around 50USD
