This has happened to me twice now. I'll be in third gear...holding it around 30mph...and my engine will just shut off. All the lights on the dash come on. And when i crank it back over, it starts right up with no hesitation. My SES light is not on, and it is stock under the hood besides a k&n intake.

Any advice? Could the car be throwing codes right now even though my warning light is not on?

 

did you just put in any mod?

 

nope. everything has stayed the same for over 6 months

 

Check the battery terminal? It might be loose and might have moved around when you hit a bump! And if its dirty clean it off really good with a wire brush!

 

if it was the batter terminal loose wouldnt the lights turn off too?

 

Well thats a good point. lol. Just a suggestion though...hmm. sorry

 

No check engine lights?

 

Correct. nothing.

 

Check the car for stored codes. Sometimes it doesn't throw a cell light. I've had it happen a few times.

 

A long shot, but I had this problem in an old car and it was the ignition switch (behind the key lock cylinder)

 

ok thanks guys i'll go to autozone

 

if the check engine light is OFF... autozone CANNOT check it... their code readers only check for codes that are ON... no stored codes...

*i work there.

 

are you coasting at 30mph?..if so.. check the idle learn it may be idling to low and the iac is not picking it up quick enough.

 

ok thats what i had thought. thanks alot saves me a trip

 

to be honest i cant remember...i'll pay better attention for when and if it happens again

 

my car JUST did the same thing and its happened twice. ! I also have a K&N intake on my car too being the only mod i have. Any correlation between teh mod and the stalling? im gonna go get my ecu read for stored codes to see what is up on thurs

ill keep u posted

 

IAC could be bad. I don't think they will throw a code either.

 

ok had my z in to a nissan dealer and they looked into my computer and there were no stored codes so im kinda at a loss for why my car did this, only 2 times so far, well see if it keeps happening

 

ok payed attention to when this stall happens.....its when im in neutral between gears coming to a stop, im thinking idle air control for me. Where is that located and how much to replace it?

 

The Nissan 350z doesn't have an IAC valve; it uses a system called ISC (Idle Speed Control), which uses the dbw throttle body to control the idle speed. If you really think something is wrong in that area, then the Electronic Throttle Control Actuator is the area you want to check. I would start by checking for a vacuum leak first and then go to the ETCA.
