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

I used this fuel injector cleaning kit on my 2016 Chrysler 300 V6, and it worked like a charm! My car had been experiencing rough idling and sluggish acceleration, and after using this kit, the difference was night and day. The cleaning process was straightforward, and the kit made it super easy to get the job done efficiently.If you’re dealing with clogged or dirty injectors, this is a must-have tool. Highly recommended for DIYers and professionals alike!

Works good for its purpose. Can get messy as it doesn’t seal the greatest but what do you expect for the low price.

Had this for awhile I’m a tech for Toyota havnt had to use it yet on a customers car but when I tested it worked great. Only thing I don’t like is it doesn’t solidly connect to a can so there is a lot of wasted spray.

I used this to test and clean my fuel injectors as part of an engine rebuild.The product worked well and I recommend it...but I do have some notes:1) The "cleaning adapters" let you insert a fuel injector, and then place the adapter and injector on a can of carburetor cleaner. I tried 4 different brands of cleaners. Most leaked between the cleaning adapter and the can. One brand (STA-BIL) did not leak: it has a different type of button on the can (a large "comfort" button), with a 4mm stem underneath.The other brands (O'Reilly, et al) have a smaller "standard" button with a 3.25mm stem underneath. These leak. This is despite using the o-rings that come with this tool.In other words, to prevent leaking the stem of the can must be 4mm to achieve a tight fit in the adapter. The provided o-rings do not prevent leaking when using a smaller 3.25mm stem that does not fit snuggly into the adapter.This is an inconvenience, but not an insurmountable problem.2) When using the STA-BIL carb cleaner that fit tightly into the adapter, it maintained a lot of pressure (a good thing)...but is hard to hold together when the fuel injector is closed. You will probably want to set the tester to a continuous mode, start the testing, and then spray the cleaner. (If you try to start spraying the cleaner first, you will have trouble holding the injector, adapter, and can together while initiating the testing.)3) The modes are basically: Off; Low Power: single cycle, short burst, long burst, continuous; and High Power: single cycle, short burst, long burst, continuous4) The tester basically is just turning power on and off rapidly...simulating what the vehicle does. Perhaps "exerciser" is a better word than "tester".5) The tester does not actually evaluate the fuel injector in any way.6) The tester takes standard 12 volt DC power. You can connect it to your car battery or use any 12VDC barrel connector power supply that provides at least 2 amps.7) The high power modes are useful if the fuel injectors are stuck (such as they may be if they have sat for a while with ethanol fuel in them). In this case, the low power modes may not cycle the injectors...but the high power modes may cycle them just fine.

Good price arrived on time easy to use

This fuel injector cleaner worked AWESOME in my 1998 Jeep Wrangler TJ. I used 2 cans of Fuel Injector Cleaner Spray, 1 can for each 3 injectors and I couldn't believe all the sticky yellow crud that was inside mostly in cylinders 4,5, and 6. It was pretty easy to use the cleane, just watch a couple videos on tube if you need help. Saved hundreds of dollars doing this myself and made me feel proud with a great sense of accomplishment from the great results. You can too! The cleaner makes the fuel injectors spray a fine mist whereas before it was like squirting and drips of gasoline. (Could be from sitting for years in storage while we were off in Texas). We are just so happy they are clean again and functioning like new. The engine is idling smooth, acceleration seems like it's doubled, and hopefully the gas mileage has increased. Love, love, love our Jeep and will get another one here soon when the time is right... 5 stars!

Does not stay on fuel injector and makes a complete mess everywhere. Food will spray all over you during this no matter how many times I tried ended up having to return it.

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
