OP, this is my thread:

fuct put his input:

Thanks, I'll bring it in, maybe I'll get lucky.

DE, thanks for all the input. I did see your thread, but it seems like it's a bit different.

I'll hopefully get the car back today from paint and I can call Nissan.

Finally got the car back from paint. I took it to the dealer today. I'm dreading they'll just say "couldn't reproduce". The worst part is the warranty expires this month I believe.

Buy an extended one!!!

I knew it!, they just called and said that they could not reproduce and that the 'computer' logged abnormal voltage on three occasions and that that is what caused it.

I know this is an old thread, but I just started having the exact same issue :shakes head: guess I'll start following the advice given on this thread. I wonder if OP ever got his car fixed.

Same problem here and 2 dealerships couldn't figure it out so far:mad::mad:

Same has happened to me this year a couple times. It was before I got my FI CBE installed as well. A little gas would get it started. Hasnt happened in the last month so no clue what to think.

This would happen to me on warm starts. So faulty fuel pump eh?

OP here, Nope, It never happened again. It was just those couple of times, hasn't happened since. Sorry I can't be of more help.

I l believe there are few folks who discovered that the cam sensor went bad, and yet tripped no CEL or even pending codes. Another possibility is clogged cats -- unlikely if unmodded, but recently someone on here had that happen, allegedly on an unmodified N/A car, so assuming no key details were excluded, it can happen.

Finally, battery voltage and alternator or worth confirming are 100%

I doubt massive vac leak unless revs high intermittently and then splutters, or idle is low and or unsteady. Or, it's so massive, you should trip a CEL for a high fuel trim -- possible, but I'm leaning towards something else.

Also, AT or MT?

Just throwing this out there.
Could it be as simple as adjusting the idle?
Running the AC along with low idle caused my Miata to die every time i let off the accelerator...turned off AC. All was well again but we adjusted the idle up a bit to compensate.

They adjusted the idle on mine and still the same problem...

Any updates from anyone else?
