With our machines, we can see the spray pattern as if it were in the running engine. We measure the flow and electrically test it first. Then we test the body and tip for leaks. Next we remove o-rings, pintel caps, and filters, and then we back flush it and place it in our Ultrasonic tank. While the tank is running, the injectors are also being pulsed at different RPM's. This helps to knock out all the carbon, wax, and rust. Finally we back flush it again before flowing it, so we can check the results.

We also pressure test the injector for leaks at the body and tip. If the injectors are not acceptable, we will repeat the entire process again. If they are in speck, the o-rings, pintel caps, and
filters will be replaced. Each set of injectors will be returned, with a copy of the before and after results.

Question and answer

Q. What education and/or training do you have that relates to your work?

A. People like us that perform fuel injector cleaning are constantly learning. from the injectors that we clean to talking with our customers and tech's from other shops. Feed back is very important.

Q. How did you get started doing this type of work?

A. We opened a auto and diesel repair shop. We new dirty fuel injectors were a big part of why some vehicles did not run properly. We new we had to be able to service our customers fuel injectors and not have to send them out of town to be serviced. That led to us servicing injectors for other shops, do it your selfers, race teams and government agencies. We have serviced injectors for shops as far away as England.

Answering questions about fuel injectors

Q. Describe a recent project you are fond of. How long did it take?

A. Well lets see if this works. I serviced injectors for a repair shop and after they installed them they worked great, it came in not running. When the car left the shop it ran great but after a half of a day the car started to misfire. Talking with the shop owner we thought maybe for the first time my service may have failed , even though it ran great for half a day. More investigation, the shop owner drained the fuel from the tank and found the fuel was contaminated with what appeared to be syrup. Well looks like my injectors were not at fault but the complete fuel system including the tank and injectors had to be re cleaned.

Q. What advice would you give a customer looking to hire a provider in your area of work?

A. Ask questions:
What kind of results can I expect from your service?
How long will it take?
What is the best and worst case results.
If my injectors wont clean up, what are my options?
Do you get good results from this style of injector?
If my injectors test to be ok, do you have an idea what else could be causing my problem?
Tell us why you think your fuel injectors could be in need of cleaning.

Q. What questions should customers think through before talking to professionals about their project?

A. I wish they new that cleaning fuel injectors wasn't like washing dishes. Some times they have to be cleaned over and over before they are correct.
