FUEL INJECTOR CLEANER
DESCRIPTION
To improve fuel injection performance, Mazda has tested and approved a highly effective FUEL INJECTOR CLEANER. The kit and cleaner is recommended for all Mazda fuel injection systems. Mazda's Fuel Injector Cleaner uses a chemical "reducing agent" rather than the common solvent used in the typical aftermarket cleaners. As a result, in tests against aftermarket competitors, Mazda's cleaner outperformed all others and was the only one to restore the fuel injector's flow rate to the original factory specifications.
Dirty fuel injectors are an increasing common problem. Many cases are due to gasoline deposits such as gum, resin and sulfur. These deposits can cause stalling, difficult starting, rough idle and diminished power.
As with carburetors and spark plugs, injectors are also subject to deposits and contamination due to poor fuel. This can create many driveability problems such as hard starting, rough idle or poor acceleration.
To help combat this problem, Mazda has authorized the use of Chevron Techron Gasoline Additive which is a detergent that is added to the gasoline.
This product can be used as a temporary measure until a good quality gasoline with adequate detergents can be obtained.
This product is available from your local Chevron Distributor in 12 oz containers, which will treat one tank of fuel.
NOTE:
This includes RX-7 models also.
WARNING:
Be sure to read and follow the instructions given on the Techron container.

Thanks IceMark,
I've been reading alot of threads and archives and I search everythin I do and buy here. For the most part I trust the fourm for these things. My only followup question is, Can anything be done to remove the carbon buildup in the engine short of a rebuild?

When I had my injectors out, I did the following to clean them- whether or not it worked is another story.
I blasted them backwards (through the output oricife) with carb cleaner through the straw, then submerged them in kerosene (had it for engine cleaning) forabout 12 hours, periodically opening and closing each one for a few minutes with a D battery. Took them out of the kerosene, and blasted them again.
Who knows if it did anything though... Kerosene?
Any thoughts?

For everyone's 411: the "common solvent" they are referring to is kerosene.

Now, about this maintenance debate. I am personally a fan of water injection. Not the type turbo guys run to keep intake temps down, but the type you do in your driveway as a maintenance procedure. Find a vacuum line or lines (teed together) that feed both the front and rear rotors, grab the throttle and rev the engine up to 4k or so, and dip the hose in a jug of water and let it drink. The water gets pulled in, hits the rotors and turns to steam, and takes carbon (slowly) with it.
If you're starting with an original/old used engine, Id do this 3-4 times weekly for about a month to clean as much as you can out. I'd also do 2-3 gallons per treatment. From then on, once per month. IF Im maintaining a rebuilt engine, I do this once per month or once per thousand miles to keep everything clean inside.
I have torn down engines where I had previously done this treatment, and they are always very clean, if not carbon-less altogether. The water treatment, along with straight premix, would result most likely in a rotary engine that lasted over 200k miles as the rule, rather than the exception.

One person suggested that i mix a certain type of paint thinner in my gas and run a tank of that to clean them.

Okay, let me get this straight (oh and for those who don't know by now, I'm pretty sure I'm a complete idiot). I should 1.) Start the car, 2.) disconnect a vacuum hose (air, right?), 3.) put hose in bucket of water to suck into the engine, 4.) do this for how long?, 5.) do a couple of times a week to get all the carbon out.
Thanks again to everyone who is posting, this sounds like it might make good information for a faq.
