THIKPOUniversal Fuel Injector Tester Cleaner Tool Kit, DIY Cleaning Tool with 8 Pulse Modes, 4 Wire Dual Channel for 2 Injectors, 8 Size Adapters, 12V/5V Output Power

Works great! Cleaned four fuel injectors on a 2010 Mitsubishi Lancer. Here's how I did it: purchase this item with two cans of STA-BIL Carb/Parts & Choke Cleaner. Remove all four fuel injectors from the fuel rail. Clean the outside of each injector thoroughly with the STA-BIL. Follow the directions to assemble this item. It attached easily to the car battery. Put it on mode 5, plug the leads into the first fuel injector and press the Pulse button. You will hear the injector clicking repeatedly until you press the Pulse button again. Now, remove the trigger from the second can of STA-BIL. This will be the can used with this device to clean the inside of each injector. Remove the original o-ring from the first injector and replace with the black o-ring included with this item. Find the best fitting adapter and slide the fuel injector into it. Place the adapter on top of the can of STA-BIL (with the trigger now removed). Pulse the injector so it begins clicking and simultaneously spray STA-BIL through the adapter and into the clicking fuel injector. It should start coming out as a consistent mist after just a few seconds. Spray into a bucket to avoid saturating the ground or your garage floor. Repeat for the remaining fuel injectors. 15 year old car runs great after this treatment! Much better acceleration.

If you have injectors that you are unsure of, this is the tool for you. Remove the injector in question (in my case, all of them). Spray some carb cleaner on the inlet and outlet of the injector. Hook up the wires to your injector, I used aetting number 6, and use a blow gun. Press the pulse button, while blowing air from outlet to j let of injector. Cleans them right out. And if it doesn’t, the injector is no good. Best tool I’ve bought. Fits any injector. Very easy to use.

Really good price and it worked extremely well on testing and getting my injectors in stuck. My only issue was the cleaner brick that you are supposed to use to clean the injector leaks very bad in the small hole

Unless you are very careful, you will get sprayed with carburetor cleaning fluid. Got to play, with it, and once you figure out which one, fits your injectors add a zip tie for added pressure. Once you figure it out! You're going to love using it.

Works great. Be ready to get carb cleaner sprayed in your face.

Works great to test injector failure, but testing the spray pattern was less successful.To test the injectors "dry" as a good/bad injector, the tester worked great. I had two out of eight bad injectors. As I was trying to determine if my issue was injectors or coils, it solved my delema on what to fix, and replacing the injectors solved the problem.When attempting to test the pattern, the pressure from the cleaning fluid would frequently push the injector off of the adapter. I found I needed an assistant to hold the injector in place, while I started the cleaner flow. This might also be accomplished by clamping the injector in some fashion.Overall, it solved my problem at a minimal price, avoiding my throwing parts on the vehicle blindly to fix two "cold" cylinders

Great tool for cleaning your fuel injector and for testing if your injector is working properly

Used once so far and worked perfect. Tested function of fuel injectors to ensure they were working and providing the proper amount of fuel.
