I just bought a dual-honed SVT UIM to replace my single-honed one, and I need someone to "ID" the parts on it I need replaced. I have an older underhood picture from my car with arrows/numbers pointing to the parts I need. I'd post a closer pic but I can't get my digital camera to work right on my new computer. The picture is here . I'm almost positive #1 is the EVR (Electronic vacuum regulator). It's vertical with a black round-like cap on the top. #2 I have no idea what it is. It's right on the back right corner of the UIM and is horizontal. Looks like it might have something to do w/ the IAC??? And last, #3 are the two black hoses that connect to the top of the UIM around the TB area. Also, how hard are these to replace? I'd greatly appreciate any help you guys could give me. My service manual CD-rom won't zoom in close enough for me to ID these by the manual.
