THIKPO Universal Fuel Injector Tester and Cleaner Tool Kit, DIY Cleaning Tool Kit, 8 Pulse Modes, 4 Wire Dual Channel for 2 Fuel Injectors, 8 Size Cleaning 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.

Why did you pick this product vs others?:This is what you need to clean your high pressure fuel injectors!! Fixed a 2016 hyundai accent that was running awful, by pulling out the injectors and cleaning with this unit. do yourself a favor and use the b12 chemicals! run that through your injectors, and save yourself $$$. I recommend doing this BEFORE you take your car into see the mechanic! Oh and the intake manifold on the Hyundai Accents- pita!!! but eventually I got it running right!!

I cannot give a perfect review because the product requires hand strength I no longer have. I used a work around to be able to use the Thikpo product. It works fine testing fuel injectors. All eight modes tests the spray patterns of the injector successfully.

Ideal for routine injector maintenance, restoring fuel efficiency or for diagnosing misfires or poor engine performance. Paired with compatible cleaning solution and pressurized cannister or air compressor, it effectively restore fuel flow. This tool is very much user friendly with clear label and step by step instructions. Kit offers excellent value for the price, considering what professional shops charge for fuel injector cleaning services. For DIY guys who frequently work on vehicles, it pays for itself in just one use.

This tester is great, takes a little time getting the feel for cleaning injectors but it gets it done. the only con for me was the power cord is way too short {had to add about five feet) to keep it away from the battery. do one injector at a time and hold the tester in one hand away from the cleaner or it will mar the tester's face (what would you expect you're working with acetone).

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

It fires the injectors as intended, how long it will last for this price is the question... You ALWAYS get what you pay for... unless you're at a flea market... LoL

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.
