Hey guys, this is actually my first post here and just liked to give a little basic info first. I currently own a '78 280z and am located in SoCal. I recently just got the car back from Mike's Z Shop in Whittier (they do great work by the way and very friendly) after completing a transmission overhaul. This problem started occurring last night, a couple days after i got the car back so i don't think it has anything to do with that issue. So usually when i start my Z up I give it a little gas to ease the start up (also note that I am running triple webers) but last night as I did the same thing I got a loud chirping noise in return. I drove the car home fine and noticed the sound only occurs towards the low-mid rpm when I give it gas in neutral. If anyone have any insights as to what might be going on here, I'd greatly appreciate it! It's nice to meet you all and have a wonderful New Years Eve! -Matt
