Ok, so ran a 12v switched to it and the car just idles at 2k all the time. But... while my Ice cold A/C is blowing... the problem goes away. Anyone got a Vacuum diagram for the 79ZX? Would like to go through and triple check everything.

So... would unplugging it disable it? I saw that and saw no adjustment screw or anything. Both VAC lines under the TB are blocked.

Alright, I blocked off the BCDD like was stated in the writeup... and I still have the issue. Between the AFM and the TB there is only one hose, on the top. It runs to something on top of the intake manifold. If someone has a picture of the BCDD, as I can not find it on my tech drawings of the motor, I would appreciate it. Jason

Sweet, I think that I may just check and replace all the lines. Thanks again! Jason

When the car is in motion it idles at 2k, when the car hits 10mph or so, it returns to normal idle. Every once and a while the brakes get squishy. I looked for the brake booster to check vac and nothing is wrong. l28e, 1979 280zx, stock mostly... 5-speed. Thanks in advance

Pics will be up when I get it cleaned up.. and its a 5/79 build date. HS130-152492

Hey, I am a proud new owner (Second owner as a matter of fact) of a 1979 280z non-turbo. I have a 1992 Nissan 240sx and when I saw this car for sale I could not pass it up. Just going to post all over here looking for information, but I will use the search button first. Thanks, Jason
