For some reason whenever i drive my car and put it in neutral the RPM's dont go down to 750 like it should .. it stays at 1,300-1,400 RPM it only goes down to 750 RPM when i come to a dead stop, but when im rolling in neutral it stays at 1,300-1,400 RPM... is there something wrong with the car or is it because of cold weather... Even when the car is fully warmed up it still does this ... i just started to noctice it .. it is kinda werid..... is this bad for the motor to do that ? Anyone help plz

Thanks,
Cam

i think it goes like that cuz of the wheels rotating

wtf are you talking about an auto or manual? I dont know about autos, i never drive them but in my manual teg when ever i put it in neutral going 40 or any speed the rpms drop to 750 ish right whenever i put the clutch in. The drivetrain is seperated from the engine whenever the clutch is disengaged. Therefore, the speed of the wheels wont affect engine idle speed.

exactly. the wheels spinning should have no affect o the motor when the drivetrain is disengaged from it. as long as your clutch pedal is depressed, the trranny and motor are two seperate entities. my car drops to idle and stays rok steady even if i pop it into neutral at 80 and coast to a stop

i notice that too. My cars rmp is about 1100 -1200 rpm when the car is still rolling on neutral, but as soon as i stop, it goes back down to 750 or so..

PLAGUED_DB7

Is that a bad thing??

I will be hauling *** then coast downhill @ about 70-80ish and the rpm's stay at about 1100-1300 never higher never lower..... when I stop 750+/-

after letting go of the gas mine will drop down to 1100 rpm right away, but it probably only stays there for about 10sec(if that) I've notice if you continue to coast it will actually goto 750...... this happens after the manifold vacum stabilizes......

or

maybe the IACV is reading the ecu with is reading the pwr steering speed sensor with inturn tells the IACV to open due to the additional load on the engine.....just a theory....

maybe someone just wants us to think he has a manual? mine never goes to idle...always stays up a bit... maybe ur car is like, dont u ******* dare put me in first...i better rev a bit...haha

no big deal. quit freaking out about it. just drive.

My car has been doing this as well ever since I got a chipped p28. Most of you guys are idiots and don't know ****, so don't respond, but here are the symptoms... IntegraLs94Cam let me know if this is a simillar problem...

Driving in gear (manuel), coming up to stop sign so you kick in the clutch and break. The engine revs to 1500 rpms. (actually revving not just SLOWLY falling), and the engine stays perfectly at 1500rpms untill you come to a complete stop. So even at 1mph the motor revs to 1500rpm... It feels like the iac goin crazy, cuz the TB is NOT getting stuck. Obviously it has something to do with the ecu. What we are asking for is a resolution...

TYIA

EDIT: What we are talking about is not NORMAL for our cars. So don't say "my car holds idle at 1000rpm till dead stop" obviously most cars don't drop all the way. This is 1500rpms, you can hear the engine revving. It's not normal, it's annoying. Sometimes the car stalls itself out too... No cel's...

what is a loser!

HONDA RR

I have a 99 gsr and it does the same thing but when i removed the power steering belt and drove the car it stopped doing that. I think its the power steering that causes that because its used the engine power to work.

^^Interesting... I wonder, if it was the power steering. Why did it only start occuring recently? I've owned the car for 3 years, and it's been only doing it for a month now.

..... why would i put it in neutral if i had a auto??? i got a manual ....

I think it is cuz of cold weather .... never noticed this befor till now ... i just wanted to know if it was hurting anything .. i dont think it is but not sure...

bump&gt;..

could it be early symptoms of a bad clutch? like when you release the pedal, the clutch doesnt disengage?

when i go into N going about 50+ it drops to about 1k rpm. and then to 500-750 @ idle.

tegsallgood

update- up top i said that my rpms drop to 750 at all times even when cruising at 80... well this isnt so anymore. just finished my lsvtec a couple of days ago and now it drops to about 1000 when driving, then when stopped drops to the 750 idle... but this doesnt always happen (i think) i dont know what it is. im sure its nothing bad. and no my clutch is absolutely fine.

OMG I can't believe that I'm the first guy to say this. In Uberdata/Hondata/and AEM EMS there is an option to change your idle revs.

It goes like this:

cold rpm _____
warm rpm _____
moving rpm _____

you can adjust this. In stock form the moving idle is higher the the warm idle! so yes it's normal to have a faster idle while moving!

ok so it is normal to got to like 1300 RPM when driving ??? it only goes to 750 RPM when i come to a dead stop....

My brother cars does not do that .... got me worried .... hmmm it wont hurt anything idleing at 1300 rpm will it?

No it's fine. the default ECU is 750 at a stop and 900 when moving, yet most people see around 1,100 to 1,300 when moving for some reason which is still totally normal.
