SSnakeEater

the only two ways to clean injectors is with the liquid you buy a checker OR the extremely strong liquid that shops have. (both methods are additives in the gas tank while the engine is running)

what make you so sure its the injectors?? how many miles do you have?

I'd take them out and have them professionally cleaned.

If you want them cleaned, pull them and send them out. On-the-car cleaning may or may not work. they just stuff a bunch of harsh chemicals in the fuel rail. The problem with that is they aren't able to check for leaks, poor spray patterns, weak or broken springs.
You pay your money and you get what you get.
Off the car testing can be done in a day or two and can verify what kind of shape the injectors are in.
