That's your AACV....car ain't going to idle or run without it....it should be mounted properly and hoses clamped on tight....very hard to beleive it just fell out.

Hopefully it was just another spare part laying around in the engine bay....

It mounts on your intake plenum around cylinders four and five, just below the throttle body.

That's your Air Reg.(cold start fast idle valve)

Car will run fine without it PROVIDED the air hoses are re-connected properly.

Otherwise you'll have a huge air leak and she won't go.

My guess is it's been by-passed previously (aftermarket plenum perhaps) and finally decided to fall off.

It could be blocked off in the past and hence not affecting the engine. If that "were" to fall out, you'll have massive misfires, idle problems as it loops into the plenum.

Those usually fail all the time on RB20DETs and mechanics just block them off.

wait stop everything

u can block them off?

Correct, that's what mechanics so. Problem is sometimes on very cold days you might find you will need to slightly press down the accelerator to get the car to start.

The hose comes off the cross over pipe, into the AAC and back up into the plenum/TB. I've found out on several RB20s (including my previous car) that it was blocked off with a bolt.

Problem is when these AAC fail, no matter what you do, the idle is quite high. People often mistaken this for the IAC valve, spend hours adjusting idle, etc.

      Foreign debris, physical shock, boost leak, could be anything honestly. The danger in taking all the timing out of a tune/hitting the R&R corner is that even if the engine doesn't detonate your turbo is taking a lot of abuse from high EGT. Also, even if nothing goes wrong it is a journal bearing that is spinning at 100k RPM on boost. Eventually it goes through enough cold start/pressure cycles to wear it out.

      Possible option to replace central computer 370 V36

      By Vee37 · Posted

      I kinda accidentally saw this, and was interested, but It actually seems to replaces the whole center computer, using the existing screen and buttons. AND it may only be for a G37 and not compatible with a Japanese 370. So its not for me, but someone else may be interested to look into it. Its about $680USD. If I am understanding it right, it basically replaces/installs and android pc that integrates with the existing screen. But I could be wrong. https://gromaudio.com/vline/ The video I first saw was the following, with very little and unclear details.     Even if your not interested in the system, the video on their site was pretty comforting in showing how simple the whole centre comes out

      Import insurance in 2025

      I’m with Shannon’s for all 5 of our cars. Agreed values seem fair, premium price is okay. ($210 ish a month, all comprehensive).  Have claimed once with them for a not at fault claim with another car where my car had no damage. Was one call after the incident and an email after. Deemed not at fault so premium didn’t go up either.    I have called up and spoken with people who are not familiar with certain cars and didn’t agree with me on value or let their personal vehicle preferences effect the call. But called back later and got someone else who was more agreeable.
