Mystery Connectors

[dhkemp91]

Im having an idle problem with my Z i have checked and replaced multiple corroded conectors and things here and there. I was just looking over the engine compartment real thouroughly and i saw this connector. there is one on each side of the engine and both are badly corroded. It looks like its part of the vacuum system possibly? Not sure it has anything to do with my high idle but i still want to replace them. I just need to figure out the name of the connector or part its connected too. Here is a couple pics, Thanks for the help!

Welcome to NICO!

I'm pretty sure that's either your EGR or AIV connector, both of which are on the $400 master EFI harness. If you don't live in Cali, both of which can also be eliminated.

Your fuel clamps are also very bad, and need to be replaced with OEM type fuel injection clamps.
