Engine starts then dies

Pintsize725

That's an interesting delete. I'll have to look into it before committing.

Probably a yes on the PS fluid. Maybe you could help me get the side skirts aligned a bit better with 3m tape? I'll see if I can get a thicker version in town today.

Just double checking, are any of you able to keep the engine running by giving it some gas as it struggles to idle on start?

That's about a 50/50 chance for me. I've had instances where as soon as it happened once, I would try to restart and give it some gas but it would just rev high and then kill itself. The times it did work, it would rev up, almost die (shuttering and all) and then stabilize.

Update: Just spoke to a good friend of mine from Houston Z's. He says it could possibly be a heat soak issue with the intakes. I'm going to get my filters and MAF sensors cleaned and get back to yall by this weekend. I have K&N Typhoons which are short ram so I'm hoping this is the cause of the problem.

Similiar to yours mine struggles to reach idle, gets rough, then dies. Without giving it some gas, it would take at least 3 tries to get the car to idle without dying. So when that happens, I tap the throttle a bit to keep it from struggling and it's fine. It doesn't matter what temperature it is.

I think for awhile people called it a "hot start" issue in which the car wouldn't start after shutting it off. Mine would do this regardless of temperature - even when it's cold.

Can you get heat soak issues even without a proper aftermarket intake? I've got the K&N + MAF tube set up.

My car does this as well when its hot. That's all I got lol. Hasn't done it in about 3 months though.

Cleaned my MAF sensors last night and noticed small improvements when driving. However the RPM issue when doing a warm start is still there. I might put my stock intakes back in and see if the heat soak was the culprit.

My Nismo 370Z '11 had this happened twice, one at around 30 and close to 40k miles. I now have 46k miles and one or two times it sounded like it was going to do it.

I remembered at least one owner fixed the hot start issue by replacing the fuel injectors. At least one was leaky after shutting off the car.

Sounds like more than just one of us are having this issue.

Seems to be during very hot days after we run the car for a little bit, go inside, come back out and try and start the car.

For me, I just give it a little gas and it revs up enough to keep the car going.

I am going to be replacing spark plugs and cleaning TB's myself and see if that fixes the issue.

My car used to fire up strong 24/7. Now it fires up strong about 50% of the time.

85k on my '09 Z

I've had it happen on my '09 with 285,000kms, never cleaned the TB or MAP. happens every now and again, (has over the years, not a new thing)cold start, hot start hasn't mattered. By every once and a while I mean once every 3-4 months it'll happen once. a little tap on the gas and it's good. I don't think it has ever idled awesome. I changed the plugs about 100k ago, so it's due again soon. The TB's I looked at when I changed the plugs the first time and they were clean. I do a lot of hwy driving so they stay pretty clean. lol
Oh I have Stillen G3 intakes...

zefaulter

that may be the highest millage I have heard of on a 370z. Is everything running well? any other mods? do you drive during winter?

Limeybastard

Damn right, whats that approx 200K miles?

90 ST

Yeah, I haven't heard of one as high yet.
G3 intake
Magnaflow exhaust, had a CNT Racing one first, liked it better
Hypertech programmer
I had the SL done twice, once because it failed, the second was the recall
ECU died the first winter, had it changed.
And on my 3rd CSC and Master...
Oh and I had to do the front hubs.

I'm driving down to San Diego with it leaving Calgary on the 12th to the West Coast, (Vancouver) then all the way down the Coastal Hwy, then across to Vegas, and home, I should be about 300k buy the end of the month. I want to get to 400k before I sell it.

And yep I drive it all year round, I run a 350Z 18 with winter rubber.
