Any chance someone out there has a schematic or pictures of the proper routing of the emission lines running from the intake plenum on an LT1 ('93)? I recently installed new injectors and since then I get a very high-pitched squeel when I shut her down. She's also running a bit erratic. When I wiggle the vac lines on the passenger side of the plenum, the pitch alters; it's obvious that's the source of the pitch. I've got all new fittings and lines to replace these with, but I'd like to be sure I haven't run the old lines incorrectly.

Thanks for any help/direction!
It should be on your radiator shroud, that's where this came from.
Yes, I have that and have everything running accordingly. There is however a second fitting above where the FPR line runs into the plenum. This line has a check valve (which was cracked and replaced) and eventually goes to 2 other destinations. I can't see where they should go and it's not shown on the label. That line appears to be making the squeel.

One goes to the cruise servo, the other goes inside to the A/C.
