EGR vacuum lines? code 32

does anyone have a diagram for the vacuum lines in relationship to the EGR? i got this truck from the auction, and the EGR / emission lines have been tampered with. it had 6 vacuum leaks when i got it. got all of them fixed. unfortunately, 2 of them looked like they needed actual hoses (i put rubber plugs over the vacuum inlets). they were both in plastic sensors im guessing, one in each on each side of the engine. Unfortunately this is my first EGR vehicle and i havent the foggiest where to start looking for where those lines were intended to lead. Also, my charcoal canister only has one line leaving it from the top and 2 open connections at the top, is this normal? im throwing a code 32 if that helps.

Autozone has Haynes/Chilton manuals which have the all the diagrams you need. If you're going to keep the truck for a while I suggest getting both as they both go into detail about different things. I have both for my truck and supprisingly answered a ton of questions and saved me alot of time posting questions and waiting for answeres.

i hope the chilton is better than the haynes. i have the haynes and it simply says "refer to the sticker on yoru vehicle". well the previous owner felt the need to make sure none of those stickers made it to me, so that doesnt help much. i snatch up a chilton today, see if anything in there is more informative.

those little plastic hard lines (vaccume hoses) suck on that engine.
I kept having the check engine light come on my truck for the EGR code and
after I repacled the hoses with real rubber vaccume hoses the problem went away. Mine is 92K1500 5.7.

I don't recall too many vaccum lines on that engine? EGR vale and EGR solonoid ?

I believe the "sticker" you're referring to is the Vehicle Emissions Control Information (VECI) label. You can order this from the dealer - you'll need to have the VIN number ready for them. I actually need to get one for my truck as well, but haven't bothered in the last 1-1/2 years.

Also, you could opt to take a (good quality) picture of the lines/ports in question, and folks would probably be willing to tell you where those lines go. I will say that most vacuum lines on fuel injected vehicles seem to be EGR or cruise-control related. Speaking of which, does the cruise control work at all, does it set but not hold, etc.? That could clue you in as to what component is being affected.

Don't worry, Chevy doesn't have the market cornered on those hoses. My Chrysler Town & Country has 'em too, and Chrysler is *extremely* proud of them as well. I priced out two of the longer ones at $60 each as they break like a twig, dealer item only. Yup, vacuum hose is a *very* cost-effective replacement. I suppose from a technical standpoint, they (plastic lines) last longer, but only if they don't get broken by someone.
