Hi,
i've already read the 'how to clean intake' article, and plan on doing it, but my question is how to clean the inside of the injectors? Should I just let them soak in B12 overnight? Or is there a 'fuel injector' specific cleaner I can use? My reason for doing this is because I have the famous P0171&P0174 codes. I read somewhere that cleaning the injectors will get rid of the codes. Thanks for your help!

can i ask something too? Doing the LIM, you dont want to soak it in injector cleaner do you? Otherwise cleaning it might turn into some bottles+dremel brush.

Soaking the injectors will do little if any good. The portion that needs to be cleaned is not accessable in that manner.
The common manner is to add an injector cleaner additive to the fuel tank and drive the car. I like Red Line SL-1 and Chevron Techron (not the Pro-Guard series, but Techron Fuel Injector Cleaner). Don't bother with the cheap ones, they do little if any good. Normally you use one can of cleaner to a full tank of fuel, but if you suspect that the injectors are especially dirty you can run it a double that rate.
Another method is to take it to a shop where they run the cleaner directly into the fuel rail in a more concentrated form. Expect to pay roughly $100.00 to $150.00 for that service.
Still another way is to send the injectors to an injector shop that will disassemble the injectors to clean them.
In my opinion, doing the first combined with cleaning the throttle body and intake system results in more than satisfactory cleaning over 95% of the time.
Today's injectors just don't get as dirty as they once did. DRI (deposit resistant injectors) came into common use in the early 90's. Prior to then, dirty injectors were an epidemidic and sometimes required very agressive cleaning measures.

cool, thanks for the info. I am going to do the Intake rebuild and run a couple bottles of Techron through as well. (Anything to get rid of the blasted CELs!)
Thanks again!

I've read that soaking the LIM in cleaner can hurt the butterfly shaft seals for the secondaries. I used a bottle brush from Wal-Mart, about $2.39 + Berryman's. Worked like a charm.
