Stock 95 240 dies at idle - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

fatlizzard · 06-10-2009, 07:57 PM

I have a stock 95 240sx that runs rough and dies at idle after it has warmed up! seems to run ok at higher rpm but when you come to a stop the car usually dies, also has a smell when you park it like a stuck choke on an older car would have!!!
Check engine light was on for a while but it went off by itself!!!!!!!!!!!!

Check for vacuum leaks, check timing, check fuel, etc.

WIKID S4TEEN · 06-11-2009, 12:02 PM

and clean your throttle body. Mine was doing the exact thing when I first got it. After cleaning the TB, problem went away.

fatlizzard · 06-12-2009, 07:23 PM

seems more like some kind of sensor or something that is making it run too rich!!
Is getting really bad mileage and has a strong exhaust smell !!!

???

Idle Air Control Valve...

Clean it, if that don't work, replace the sumbitch.

I can't tell from inside the car but someone following me said there is lots of black smoke comming from my exhaust!

Dead/Lazy o2 sensor maybe..

S14Cuhh · 06-16-2009, 08:10 AM

i had the same thing..dying at idle and black smoke..check the vaccum line from the brake booster. i found the leak..problem solved

boosted armo · 06-16-2009, 05:26 PM

I am pretty sure this is an iacv issue. If not that, then fueling. But check that IACV first.

fatlizzard · 06-16-2009, 06:46 PM

I will check the brake booster vacum first because I do notice the brakes feel funny when it is running bad!!!

IACV - what and where is it ?
Thanks!!!!!!!!!!

Idle air control valve ?
That thing on the back of the engine?

its in the picture on the top left and bottom right

fatlizzard · 06-22-2009, 06:17 AM

Dont think its the IACV because it is also cutting out at higher speeds,
blowing black smoke

fatlizzard · 06-26-2009, 09:29 AM

Injector o-rings ?

BustedS13 · 07-09-2009, 03:23 PM

welcome to hell

my car was dying after braking to a stop at lights, also not maintaining an idle, etc
so, with much aggravation, i replaced the IACV.
nothing changed so the 240 hasn't had tags for three years now. have fun!

va240dude · 07-09-2009, 03:33 PM

check out your CEL or MIL code at Autozone, or Advance, they pull the codes for free, so that may give you and idea of where the problem is occurring. the code should still be in your system, unless you used a scan tool to erase it. eliminate the IACV first, since 240s have that issue. mine did now it doesn't cut out at idle

then we can go from there.

going over to the parents' house and pulling the s13 out of its sarcophagus tonight, gonna give that a shot and plug my brake booster line to see if it's a bad brake booster diaphragm.
fuck my life.

edit: now i have a stuck injector. if you own a car you care at all about, be sure to fire it up once a week or so, just to keep things working.

BustedS13 · 07-11-2009, 01:48 PM

went to the junkyard, pulled six fresh injectors, replaced my broken one (see pic for the HORROR), and now she purrs like a 17 year old feral cat. covered in shit.

anyhow, i capped off the brake booster vac line and gave it a spin around the block and didn't dip or die once. the problem is obviously a shot diaphragm, so i ordered a new brake booster from autozone. gonna run a few new grounds as well. then a new header and i should actually be running again. fuck my life

top= a new one
bottom= the old one
