I took my throttle body off to clean it, and realized that the injectors might be dirty too. but I do not know where they are, or if there is only one. In side the intake just beyond the throttle body are two holes the first of which is guncked up and and the other looks clear, both look like they deliver fuel. What are they and how do I clean them?

 

The fuel injectors on the bottom manifold, there are six. You can locate them by following the intake runners too where they enter the heads. Right before they terminate at the heads, that's where the injectors should be. The fuel rail sits on top of them, which looks like a backwards E.

 

Thanks hawaii2.9, I haven't had the time to look at how it, now that I know where to look, it will be easier. still dont know what the two holes in the intake are however, any ideas?

 

The first is a catch all resevoir molded into the plenum. It will usually have oily/fuel looking crap in it. I just clean it out by poking the tip a rag into the hole and soaking up the contents.

If I'm not mistaken, the second hole, actually has a hose attached to it, on the under side of the plenum, and is part of the exhaust gas recirculation system.

From the things that you have said so far, I strongly recommend that you do nothing more than locate the injectors, just so you know where they are.

Don't attempt to do anything to them, until you are completely knowledgable about the whole top end of your engine.

Even then, you need to have a good ampount of hands on experience behind you, befor you get into injector removal, cleaning, replacement, etc. You can easily kill your engine, messing around with the intake and injectors.....

 

My ignorance is both a result of not enough time, and too much time away from the shop. Though my skills are limited to body work and restoration, I have actually built a few engines. Only one of which was fuel injected, I will move slowly however and probably not even mess with the injectors now that I know what I am looking at on this engine. Thank you Elwhoppo for explaining the two holes in the intake, that was my main question. I'll keep ya'll posted.
