I'm changing my PCV system and with the fuel rail off, I'm wondering if I should clean the fuel injectors. There was a tiny bit of crud on them when I pulled them. I read elsewhere (not on here) people have used ultrasonic to clean. My buddy has a Harbor Freight ultrasonic machine we used to clean our old Suzuki GS motorcycle carbs so I'm wondering if that is an option.

Here is what the intakes look like on my car once removed.

 

The ultrasonic cleaner will work for cleaning the fuel injector. You really need to change the o-rings and filter basket as well. The only problem with doing this yourself is you do not know if the injectors are flowing the same. I sent mine to Race City Injector in North Carolina. They only charge $20 and you get cleaning, before and after flow testing and a report showing you the results. check them out at Race City Injector
