Anyone into fuel injector servicing/cleaning? I sent the injectors from my '00OBW to witchhunter performance for their cleaning and flow service. They came back nice and spiffy with new o-rings and stuff. I had new OEM o-rings and other seals on hand anyways. They replaced the little filter jobbies in them too and sent back flow test results. Showed a little more flow after service; but I think they were fine even when I sent them in.

Price and turn-around time?

I think it ran 15$ each return shipping included for the 'premium' service; they have all info on their web site. Turn around time was, I think I sent them out Thursday (priority mail flat rate envelope) and I received them back on Monday or Tuesday. Only issue I had was they sent them back insured, so post office wouldn't deliver them without my signature, that delayed my getting them by a couple days.

yes i've had it done before. i've used rcengineering. much more expensive than the guys you used, but someone at XT6.net used them and felt service was good as well. the older injectors, approaching 20 years and 200,000 miles are well served by getting cleaned/rebuilt. pre and post testing can show dramatic differences.

Besides mileage, how did you decide that you needed injector service? Is there a test?

Well, I just figured I'd send them in and see what happens. I didn't have any other reason (other than mileage I guess) than I had the car down for awhile anyway for the 105k service and had the air intake stuff out of the way, washer bottle, battery, etc., so I figured it would be the perfect time to send out the injectors too. Anyway, I don't think they really needed servicing in hindsight, but it was fun nonetheless.
