Fuel injector cleaning without expensive tools 

Thanks, I'm glad it was helpful.

This guy is amazing dude thank you

Its very instructional for a science project.

How do you know if one injector is leaking?

This is an awesome video!

+EndofUSA Hey Thanks.

EndofUSA luuuuuuul

hell ya

@@sixtyfiveford Great Vid! Does it matter which way the battery terminals are ? Thanks

Spraying it in reverse first should clear out any crud in the filter basket before spraying it the normal way.

I use a piece of heater hose and clamp it on the bottom of the injectorand clamp a valve stem in the other end then fill it B12 chemtool and energize the injector and let it drip through the first time then fill it a second time and blow it out with the compressor the switch directions and do the same from the top works great and you don't have to try to seal the straw to anything

Glad you like them!

Thanks, I'm glad you tried it out.

Thanks, I'm glad you liked it.

Awesome.

Hi, video is really helpful but your suggestion is also good. 👍👍

If you aren't in a hurry you could dab a little in weld around the tube / hole for nice seal

And just a touch of hot glue. 🙂

Dang... 5 years later I need to come back an re-watch the video and my original comment. Time to do it again!

Thanks.

There's something fundamentally sexual about this comment... Maybe it's just me

@@Kharlis007 omg reading it back now 🤣🤣

@@Kharlis007 nice one bro.

Sounds like good idea

Awesome.

Nice work!

What were the symptoms? Mine losse power after 10 000rpm in every gear. Was this the solution? Is there a filter in the cbr injectors that one has to replace?

What is #5? How can an injector spray backward?

@@leomalino2364 to back flush the injector first and clean out any larger crud that may be already inside the injector.

Thanks, I'm glad you liked it.

OMGWUNSIU Very nice.

Thanks

Awesome. I'm glad you liked the video.

Robb's Homemade Life Thanks..

Thank, I'm glad you liked it.

Sounds like my dad haha

Recapping on this, yap, just as I stated, it did not impress him and after two year since then he always goes to using this trick and tells me how to do it, got to love him, but man, it makes me mad, knowing I'm just like him.

Hey Thanks.

Steven Kjeldgaard Thanks, I'm glad it helped.

To check the resistance of the injectors, all you need is a multimeter and you check the ohm's. They should be between 10-12ohms, might be 14, either way it doesn't really matter much, cause you can check them and get a base line, and if you have any bad injectors you will see a variation in the numbers. They are quite literally one of the easiest thing to diagnose, all you have to do is Pop the clip for the wires to the injector and touch the test leads of the multimeter directly to the injector and read the ohm's-then change any bad injectors.

+Mathew Wood Thanks Mate.

Thanks, I hope it comes in handy.

+wrlgmail please explain your set up in more details. I plan to clean my injectors, and I was aware of potential to damage the electrical inside the injector. So I am interested in your comments but I wouild like to get your details, please. Thank you

Hey +Sam Rafeedie - you simply need to be sure you do not apply too much current to the injector coils. In the engine control module, the injectors are activated by a transistor circuit switching on and off- the transistor has the current flow limited by a resistor (or resistance) in series with the coil. To approximate this current flow without using the entire amount of current in your starting battery, you can simply wire a 12v signal bulb in series with the injector. The current will be limited by the resistance of the bulb filament- which will increase as it gets hotter, thus limiting the current total to slightly less than would flow in the bulb alone - if you use an 1157 type incandescent lamp, that should be about 2 Amps at around 13V. Don't leave it connected for a long period - say more than 10 seconds, as the coil will heat up just the same as the bulb. One terminal of battery to bulb, other terminal to injector, other side of injector coil to opposite terminal of battery. Auto injectors are not polarized so it does not matter how you hook it up as long as the lamp is in the circuit. You could also use e.g. a 10 Ohm/5W resistor in place of the lamp. I like to use the lamp as I get visual feedback. GL

+wrlgmail Going further, To clean all at once The injectors could be left in the fuel rail(s) on the bench and a proper RLC circuit using a $4 555 IC to "pulse" the injectors. But you would need more injector pigtail leads according to number of injectors. The 555 timer circuit works with Vcc of +5v =Digital control. Latching a 6v output relay for a 1 second duty cycle, with no overheating and total load resistance spread over all the injectors. Spray patterns can be visually verified during pulsation by placing paper at injector nozzle Or in a pinch you could use a common 3.7v Li-PO cell phone wall charger for safely cleaning one injector at a time Output voltage varies between 4.2v and 5.1v with current between .500ma to 1amp output, and will not fry your injectors. Add 555 timer circuit for digital control if you want.

+Sam Rafeedie See my reply below on correct: input voltage, and current control for cleaning.

+Aye Bee Thanks. You've all convinced me to have them done at a drop off service for advanced cleaning.

@Smokey Bear precisely why I said warm and not heat... use water not a flame... if you read things in their entirety it will perhaps help you from explaining to everybody how dumb you are.

@Smokey Bear I have been doing it for 30 plus years yes you're dumb

This also doubles as a quick, cheap method to produce the famed Flash Bang grenade. Children, do not try this at home!

@@timc9893 stupid people don't try this at home anybody with common sense can pull this off with no problem you're fucking warming it up you dumb shit!!! Not even close to the temperature these cans reach in the warehouse while they wait for distribution you're a fucking idiot

@Smokey Bear and you're still a fucking idiot too

+Mark Henry Cooney Thanks for watching.

+Mark Henry Cooney You turn the knob so it is pointing to OHMS then connect the leads to the two terminals on the injector, should read around 12 ohms.

Yeah, Mark, good video. :)

Great. I'm glad you liked it.

more than that

Hey Thanks. I'm glad you liked it.

Thanks, I'm glad you liked it.

Great idea! Saves a lot of stress and time, kudos!

Compromise! Stick the toothpick in the end while you're melting the red tube in place, then remove the toothpick when it's cooled down.

Keith....Very beautiful idea.

Because there isnt one way to do something

@Jason Larae month

Mineral spirits ?

You mean republishit don't you?

mustie1 Thanks.

Ohh wow well hello Mustie 😁

+Raul Romo Exactly! People get hung up on the smallest details. Thanks for your comment.

Thanks, I'm glad you liked it.

Lizard King it aint a party till ya add in the 12V battery. Hold ur tampon in.. cuz that powder kegs' about ta blow...!!!! Lol..

Live a little

Lizard king, do you spend your mornings in a bubble?

Thanks, I'm glad you liked it.

Yeah, I seem to find a million uses for them.

Go to literally ANY tire place. One tire stem valve should run you about 3-5 dollars if they don't just give it to you.

Nate Miller No, they don't.

Check this out. /watch?v=8rk0tKtiVic -Simple and cheap.

+Nate Miller, Just use a lighter and a small nail then.

+Nate Miller Did you watch this video on a rock you found in your garden? :-)

There's always someone, LOL

and how many shady tree mechanics do you imagine have access to that equipment?....

Sorry Eddie, but I've given this a 'thumbs down'. Pumping cleaner through your injectors while they are still in situ will spray the cleaner straight into the inlet runners of your engine, from where it will run into the cylinders and down the bores washing away lube from round the rings and contaminating the oil in the sump. Also, removing the injectors from the car means you can SEE the spray pattern, so you can visually check for a good fine spray.

+Cyclone Cyd, I agree. Taking them out is better...but when not taking them out works....I'm talking about while the engine is running so that it doesn't contaminate the oil and potentially cause engine damage.

taking injectors out is the best way. rarely is the nozzle clogged. what clogs is the screen on the inlet/top of the injector. the only way to clean that screen is either liquid pressure, ie, can carb cleaner, or air pressure from your air hose. reason ? have you ever cleaned a screen? you clean it from the other side. by reversing the normal flow, anything stuck in the screen will be flushed away. Injector cleaner additive is a useless product. if the injector is clogged the cleaner is not even going to reach the injector because its screen is clogged. Obviously you can't spray the other side of the screen on an injector but carb cleaner pressure is enough to clean the dirt off of the screen.

+dale crawford Makes very good sense! Also, this is one of his most beneficial videos. I dunno about the inkjector cleaner rig comment, because this vid was about low bucks and high results.

Thanks.
