Injector cleaning question

jer28 · Mar 14th, 2004, 02:13 PM

Well while I have my head pulled off I noticed that one injector looks like it is not really working all that well (the intake tube is very clean as opposed to the other 3). I did not notice a big loss of power, but there does appear to be a problem. My question is how do I clean them once I have them off the rail? I think I need to get them to open somehow so I can get the nozzles clean. I already tried fuel system cleaner when the car was running and obviously that is a waste of money. Does anyone have any tips?

yeah, don't do it yourself. if you can, send them off to rc engineering or someone who professionally does it.

or just buy a new set....I don't imagine ga16 injectors are that expensive.

re-built injectors cost anywhere between 80- 140 EACH! thats damn expensive if you ask me.

Thanks for the replies guys. I just have a tough time paying 24 dollars for each injector being cleaned. I'll probally end up breaking something in the process of removal\cleaning so yeah james I may need to get ahold of you.

just a forwarning... my injectors are used too!

How does $11 each sound for a complete flow test and ultrasonic cleaning from Cruzinperformance.com, a site I bookmarked about two years ago. You'll have to pay shipping to and from the company as well. I'd love to have this done soon for a performance/effiency aspect and to potentially eliminate my erratic idle.

Great, thats a much better deal (2 for the priceof 1!). Thank you very much for the link.

what about an EFI service for those with the injectors still on the rails. i did one to a customer's 330i, and felt quite a difference, and now i'd like to do the same service to my own car, but curious if anyone has done this before.

didn't have the time and the chemicals to do an EFI service yet, but was able to do a De-carbon service, other than throwing the MIL with multi-cylinder misfire faults, the car runs a bit better, and the smoke show was a lot, my shop foreman thought i was doing burnouts in the parking lot, but i'll see if i can get the stuff for the EFI service.
