I think it works a bit better too if you put it in while the tanks about empty right before you fill it up.

The best cheap way I have found is to buy one bottle each of:
Techron Concentrate Plus
Mopar fuel injector cleaner
Napa Auto Parts 'Kleen' two bottle pack

and then put them in your next 4 tanks of gasoline.

For the highly effective but more expensive way

which can clean and test 8 injectors at a time.
There is an added advantage to this, because after testing you can install the highest flowing injectors in cylinders 7 and 8, which in most 5.2/5.9 V8s need a richer mixture to keep from pinging.

My Dodge dealer has a device that bypassed the fuel intake so special cleaning agents can be run through the injectors (probably the one listed above). It's costs about $80 to service. Personally, I run Lucas Fuel Treatment and at every oil change (3k) I run a solvent based cleaner through the tank with hopes that it keeps the in-tank fuel filter clean.

I had a huge problem with my truck. I kept getting misfire errors, and a fuel bank too lean. At first thought maybee it had something to do with the plugs and spark plug wires. Yeh they needed to be swapped out any way, although no change in the ****ty gas mileage. I put a new coil in, recomendations of a buddy ,although it had passed the check out in the haynes manual. No difference. Then I decided to get into it. I pulled the Valve covers, throttle body, fuel rail and all the injectors. I broke down the throttle body ( not much to it ) cleaned it up real good. I used a can of throttle body cleaner in this by itself.Air Intake Controller is was practically closed with so much carbon. Cleaned it & Set it aside. I relived the pressure on the fuel rail then pulled out the 4 bolts holding it on to the Intake. Sprayed a buch of carb cleaner in the Air Intakeand touched it up with Q tipsthen vacumed it out with the shop vac . All the injectors came out the O ring kit was $2.00 at Auto Zone. Cleaned all the injectors sprayed carb cleaner in each one from both sides and hit the tops & bottoms with a Q-tip. Greased the injectors & the new o rings with some vasoline ( germans call it weiner slider ). Cleaned the ports on the fuel rail same method Q-tips and Carb cleaner. Went ahead and cleaned around the valves and spiffed up the valve covers. Before I put the fuel rail back on, I blew it out real good to make sure there was no Q-tip fuzz on anything else. End result better gas mileage and no more error codes. Spent about 10 buck and took around 3 hours with the boys helping. 1 can throttle body cleaner, 1 can carb cleaner, 1 small box q-tips, & O-ring kit......Hopefully this helps J

The best way to clean injectors is to use a sonic cleaner. Look for a jewelery sonic cleaner at Wal Mart, Sam's, or some other kind of store. The basket has to be large enough to hold the injector. Mineral spirits work well as a solvent. Just fill the reservoir with the solvent, dunk the injector, and let the cleaner run its cycle. Three of my eight injectors were clogged when I rebuilt my engine, and I had a friend who owns a jewelery store clean them. They looked brand new and have been trouble free since. From that point on, I run a bottle of Lucas injector cleaner and lubricant about once per month through my engine.

I like Sea Foam the best. I pick mine up at Autozone. I use it in the fuel tank as well as the crank case. Every "Real" mechanic that I have ever talked to swears by it.

I am 18 years old and no where near a "real mechanic" but boy will I SWEAR by Sea-Foam! ^^^

Just pop off a vacuum line, pour some sea-foam in a cup, have your friend work the throttle so the motor doesn't stall, and keep dipping the vacuum line into the cup. After you've used almost all of the sea-foam in the can, pour what's left in the cup, tell your friend to stop working the throttle, and dunk the vacuum line into the cup, letting the motor stall itself out (hopefully). After it stalls let it sit for a good 10-20 minutes, depending on how long you're willing to wait. Start the vehicle up (it might take a few moments). After it's started rev the motor to red line, then 4k, then 3k, etc... Then rev to red line a few times. Keep revving the motor until no more smoke/soot is pouring out the exhaust and PRESTO! Your ****'s clean! (Make sure you re-connect the vacuum line; I prefer to use the vacuum line on the brake booster as it seems to have the most vacuum)

Never said it did. But it will clean your intake, piston heads, valves, and TB (if the vacuum line permits). I was mainly trying to back up Sea-Foam as a product. I'm sorry it didn't 100% relate to the subject at hand, which is how to clean the injectors. Good luck

Will using plain water in a sonic cleaner damage the injectors?

With the cavitation process of a sonic cleaner what solvent is safe to use? seafoam? plain hardware solvent or those specialty detergents that is specifically made for a sonic cleaner, which is like simple green. ( I read somewhere that the caviation process is as hot as the sun temperature? is that correct?)

Do not use water to clean the injectors. You sure as hell wouldn't use water to clean a carburetor or any other fuel related component, would you? [] Mineral spirits or any other solvent for cleaning parts in a parts washer. As soon as I can, I am going to repost the pics from my engine building thread so you can see the before/after process.

All of the people suggesting Seafoam need to know that it isn't going to do squat on a plugged injector.

Mopar fuel injector cleaner is at the dealership for about $7

Chevron Techron Plus at Chevron stations or Autozone for $10-12

Kleen 2 bottle set is at Napa Auto Parts for $14

Ring Free is at Yamaha outboard motor dealerships

Pep Boys usually has SI-1. BMW injector cleaner is also Jectron.

If they are out of the engine, go with the ultra sonic cleaner. If in the engine, do as HankL suggested.
