Clogged D-Jet Injector, How/Where to clean. Options

[Britain Smith]

It appears that the recent introduction to autocrossing is causing havoc on my little 1.7 since it was previously living a plush life with an old guy. Anyway, one of my injectors had to be replaced with a used one last night because it was clogged. The used injector worked much better than the clogged one, but not as good as a brand new one. All the injectors were replaced with brand new ones not to far back and I would like to put the clogged new one back in if I can get it cleaned out and working correctly.

Does anyone have any suggestions on how or where to get an injector cleaned?

Mark, I just caught your post on the home made cleaning device. I would like you input. I load amo for my sons service rifle matches. We use a vibrating bowl to clean the brass. What would be your estimate if we placed an injector in a sealable container with FI injector fluid and placed it in the vibrating bowl for about an hour? I may be able to come up with a 3V source and connection to be contained in the sealed container to open the pentle. I would appreciate your thoughts.

Many regard rebuilt injectors to be no better than older. Brad shared a site that sells quoted new 2.0L injectors for $56.60each.http://catalog.thepartsbin.com/

Should work, you might have to put a non-slip mat or something to stop it from slipping around.

Opening the pintle may help but the wires could come off, if you try this use a non-flamable solvent!
I don't know if holding the pintle open like this (for a long time) will hurt it or not. I also don't know if the fluid would/may cause a dead short.

One thing I did find is if the pintle if frozen it's toast, out of 8 injectors with frozen pintles only 1 freed up. This was with 8hrs on each injector! With a blunt pin you can push on the pintle and feel it open.

That $50 is for all 4 to be cleaned and to come back good as new and flow tested to insure their performance.

My bad, Britain was talking about 1 injector so I thought you meant each.

The price of injectors have come down so if you have real crusty injectors I'd just get new ones.
