Idel issue after fresh sr20det install - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

LowNSlowG · 07-03-2015, 06:53 AM

z32 MAF
255 fuel pump
550cc inj
entahlpy tune
BOV is recirculated

If you run the car in boost then let off the throttle and put in the clutch it will dye out unless you feather the gas.

I had it even cut off on me not in boost, just coming to a stop and depressing the clutch and it will stall out.

Anyone have any ideas? IACV? I dont think its the BOV because it will do it out of boost.

Any help is appreciated because this is getting annoying.

Sounds like a vacuum leak.

Would the vacuum leak cause it to stall all the time? It runs fine most of the time and if you switching gears nothing happens. The moment you hit the clutch and the RPM fall it kills. It will randomly do it as well under normal driving.

Trust me I have already used the search button and that thread (which I read) is not the same issue. Vehicle down not bog down when hitting the throttle. I can keep the car running after boost if i feather the gas. If I do not then it will die out on me. Again this has happened even out of boost and just normal driving (when coming to a stop and clutch is in).

99,847 people have come with this exact same problem and its been fixed the same exact way, and you think you have the only 1 engine that doesn't have an idle speed affected by air and fuel?

heres a spoon
compression test
boost leak test
bypass test
raise idle speed with screwdriver if its too low

I don't think in one post I was ever disrespectful to you so I don't need you addressing me in that way either. I asked a simple question to see if someone could help me. If you don't like what I post then just don't reply.

Have a good one.

Cap off the bov and see if the problem persists. It's not the way you asked, it's the fact that you haven't bothered to do the research. The issue you are describing is not a new phenomenon.

If you have tried all said fixes and then come looking for help you may be received a little better.

I have clamped the vacuum line going to the BOV and problem still exist.

thats not what he said to do. Cap the bypass (PLUG IT WITH A SOCK AND TAPE) not the vacuum line to the bypass.
