8 week old Nismo 370Z over-revving
 

As the title says have got my beautiful 370Z Nismo only 8 weeks ago brand new and well pleased with it but over the last couple of weeks when I start it up from cold (doesn't happen from warm) - it shoots up to 1500rpm and sticks there for about a minute before gradually falling to the 600rpm it should be.

Not a major problem apart from the fact if I drive off immediately then I don't need the accelerator as the car simply pulls me along until the revs drop down - I can drive half a mile without touching the throttle ! Its like driving a frisky horse that just wants to bolt !

The only way round it seems to be to accelerate PAST the 1500rpm and then brake - it then seems to behave normally.

Any ideas ? I know I'm going to have to take it in which is a ball ache as I'm pushed for time and on an 8 week old £40k car !

Cheers

Completely normal for a cold start. Its to get things warmed up a little faster. You should wait to start driving until the RPMs come down anyways.

:facepalm:

:icon18:

Are you seriously telling me owning a 370Z involves sitting there like a lemon whilst your car drops revs (and everyone else has gone) and it has only started happening for the last 2 weeks - so looks like it wasn't functioning the FIRST 6 weeks ! ? The pull is very very noticable.

There was also no way it happened in my 2010 before this one

Your car would start and idle at 600rpms or so even when cold for the first few weeks?? :confused:

EVERY car I have ever driven has a cold start mode and idles higher than normal for the first minute or so. Not sure what you mean by "everyone else is gone" are you trying to start your car up and race people right away? :confused:

every sports car I've ever owned has done this on a cold start. Hence the need to let it warm up !

You could always buy a bicycle. You can just hop on and go.

:facepalm:



.......again.

Don't worry about it, it is normal.

Do this test: Start up the car and drive it for 5 minutes. Turn the car off. Turn it on again. Do you see the RPMs at 6-7 hundred now? :happydance:

It's going through the cold start warmup process and is air intake and coolant temp dependent. Normal.

I have a 2011. It has been doing this for over 4 years and 70K miles now. It gets worse when the weather is cold :twocents:

I just sit there and enjoy my exhaust while the car warms up, what's the big deal? it's only 2-3 minutes more of your time anyway.

If this is such a bother, add a remote starter and crank up the Z from afar.

I can't tell if we're serious here or not :ugh2:

Nonetheless

Yes, it is perfectly normally for the rpms to hang their till the engine warms up.

The amount of waiting will depend on the weather.

What is it about this forum?

1500 rpm is "over-revving"? Really? Try again when you tried to downshift into 5th and got 1st instead ...

The ambient temps in your neck of the woods has dropped noticeably in the past few weeks - right ?

That is the only thing to change and it is entirely normal.

Either wait for 30 seconds or ride the brake for the first 30 seconds.

If you are really aggrieved, don't blame Nissan but the numpties who force cold start/slow idle-down to avoid excessive emissions on cold-start.

At a cold start up your car will automatically give a little more gas and will slowly idle down. That is completely normal.

BTW, cars don't like to be beat at a cold start. That goes for any make/model. On hot days you can get away with driving easy at low rpm until you are up to running temp. On cold days, give your car a couple minutes to warm up a little and then ease into it until your are at running temp.

A remote start helps the process.

The main reason cars do this is to heat up the catalytic converters so they start operating efficiently faster. It's an emissions thing as others have said.

Think your butt plug needs to be pushed in a little farther. :nutswinger:

Okay Z team, leave him alone. He just didn't know. I just found out that my shift lever has to be in first gear in order to rev my engine above 5k...Who figured that one out?
