Will a 5.0L injector work ok in a 5.7L?

[VileZambonie]

They are not balanced... They are designed to have a target spray pattern. aside from that they are pulse width modulated by the pcm. The system balances itself. If you are cleaning them, then just clean them and call it a day. If you are replacing them then do yourself a favor and get a tbi rebuild kit while you're at it. You may need one of these too http://cgi.ebay.com/ebaymotors/GM-TBI-Throttle-Body-Fuel-Pressure-Regulator-Spring_W0QQcmdZViewItemQQhashZitem53dd2a5b3aQQitemZ360192826170QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

Im kind of intimidated by rebuilding the throttle body. Cause if I screw up then, I have nothing to drive till I get it figured out. I was thinking injectors cause a monkey could replace them in these trucks.

They are simple to rebuild.  I need to put the article and pictures up in the tech section where I pulled mine down, but they are SIMPLE, there is really nothing to screw up on one.

Here's some pix... it's easy

I think that the pics you are referring to have been removed.

[Captkaos]

I am going to try and upload the article I have this weekend.

[VileZambonie]

What do you mean they've been removed?

It's just to show you how easy it is to pull apart

Think there would be any point in vatting any of that? Or instead just do the rebuild, and maybe replace the injectors, and skip any cleaning/vatting.

Also, I hunted until I found a way to be cheap.   Here is the injector:... ok ...or not. Anyway, you just use that page to select the proper vehicle and engine size and part, and they do have a refurb for the 5.7L for $31 with like a $30 core charge.

And here is the remanufacturing process they put them through. I checked and you just mail in your cores and they credit the card you paid with.

I called these guys and they said that it's likely that they can even give me a balanced set, all they would have to do is check the specs and pluck a couple of remans that had the same specs after the remanufacturing process. Kinda wonder if it will actually help, but eh, who knows.

I never said GM balanced em, I said its a benefit to sending em off to be cleaned. They get flow tested to see how equal they are.

I was replying to the post above mine otherwise I would have quoted you if I was replying to you. Go back and re-read.

I also came across these babies:

They might be a safer bet than the other place I found, since the other place would be going out of their way to put together a matched set.

Hey vile, what's that thing in this pic? Is that the IAF or IAT (or whatever) sensor?

Idle Air Control Valve.

[Skunksmash]

Cool thanks I still need to replace that thing. Never got around to it, and I'm hoping it can help to cure my rough idle when I do a cold start.

[Skunksmash]

Well since my original question has been answered, I may as well use it to go off topic and ask about something else.

I replaced my Idle Air Control Valve, and it seems to have helped. But of course my old plug on the truck cracked and crumbled. So it looks like I'll be buying this:

All the wires on that are black, and all the wires on mine are color coded. Which method would you use, to make sure you wired it up right? Wrap tape around each one and label it? Also would you just use electrical tape, or would you heat shrink it? I'm going to have to say heat shrink.
