Re: Cleaning fuel injectors (c5chris)
I had a local shop do mine. They disconnect the fuel line to the fuel rails and connect a pressurized can to the system. They started the car and let it idle until the can was empty. Seemed to smooth my idle a bit.

Re: Cleaning fuel injectors (scool93535)
GM sells one of the "dump it in the gas tank" injection cleaning fluids. 'Tis said to be the best on the market by several techs. Some folks swear by it, others swear at it. I used it on my car at about 20,000 miles, did not notice any help or hurt. Of course, the injectors should be in good shape at that mileage, running Amoco gas.

Re: Cleaning fuel injectors (Gearhead Jim)
I don't believe that GM recommends injector cleaners. On the L-98, there was a TSB not to use it as it was destroying the injector insulation and shorting them out. Not sure if that holds true with the LS-1, but something to consider anyhow :cheers:

Re: Cleaning fuel injectors (vettenuts)
In the order to have some regular preventive maintenance, the use of an fuel injector cleaner product seems to be valuable.
After discussion with my GM TechDep, they as well recommend the use of FIC from time to time. They even recommend to change the gas brand from time to time due to the helpful effect of their different additives.
Personally, I use RED LINE FI-1 FUEL INJECTION CLEANER, but sorry, I can not give you any factually based results about the success and its cleaning working. My engine counter shows some 15'000mls actually - it is not my daily driver.
However, I do believe that this kind of stuff (FI-1 or similar) may also greatly assist with anti-corrosion protection through out the entire fuel system.
.....and this kind of preventive maintenance is not that expensive at all....

Re: Cleaning fuel injectors (c5chris)
My son is a Chevy tech (gloat gloat :lol: ). Everybody at his shop swears by BG44K. Pour it in the tank (they also have a separate version you induce directly for really bad buildup).
And don't forget to clean your throttle body while you're at it - dirty TBs are at least as responsible as clogged fuel injectors for rough idle. :cheers:

Re: Cleaning fuel injectors (c5chris)
Chris--Every 5k mi, I use BP 44D and/or BP Fuel Inj cleaner through the tank. At 30k mi intervals I hook up a pressurized can of 3M fuel injector cleaner to the fuel rail and let it power clean. It's just cheap preventative maint. Fuel injectors are expensive and a PIA to replace. Clogged injectors are fuel/power robbing little suckers. Whatever inj cleaner you decide on, make sure it is good quality. Some can dry out the seals prematurely.

Re: Cleaning fuel injectors (c5chris)
For a suspected clogged injector,we at the dealer mix GM top engine cleaner with gas and inject it into the fuel rail in a pressurized cylinder.The fuel pump is disabled and the car injests the mixture...It works wonders and will unclog an injector 99% of the time :yesnod:
For routine maintenance,go to Wal-Mart and purchase Chevron with Techron tank additive.It is good stuff,and it is the same stuff the GM sells in a different bottle for 3 times the price$$$ ;)
