Is your idle is just that high when you start it? Was it high once it is warmed up? The idle is always a little high as soon as the car starts, lowering as the engine warms. As for letting it warm up, you really only need to wait maybe a minute at most. Then just go easy on the accleration until the engine is fully warmed up. I actually drive around a little bit before I get on the highway to go to work, that way the engine is nice and warm for some speedy on ramp action!

 

well it idles a little over 1000 when its warm, but its in the 1700's when cold. i'll ask the projects forum for the difference in the G2 and G3 article in changing the idle speed lol thanks for the help and the speedy ramp action

 

I have this problem too I would also like to know how to fix.

 

There could be numerous reasons on why ur idling so high.

But first check to see if u have any loose bolts around ur Intake manifold. A simple turn of the wrist could solve ur problem all together.

If ur still having a problem let me know.

 

im having the same problem in my 94 integra, except its idling at about 2100 rpms. it seems to warm up and idle at around 700-900... since its my everyday driver, im worried it could potentially be unreliable. any solutions to fix this problem?? and is it even a problem at all??

 

are you saying it stays at 2100 RPMs idle when warmed up, or it starts at 2100 and then backs down to 700 - 900 RPM?? The spec for idle is 750 RPM +/- 250 RPM warm, so anywhere from 500 RPM to 900 RPM warm is good.

 

yeah, it gets warm and comes back down... it only idles high for the first 10 minutes. after it warms up it idles between 500-900RPMs.

Try that and see how it goes. Could be vac leak and other minor things too but it doesn't make your car unreliable bc of it. It's just like stepping one the gas pedal a bit all the time.

900 RPM when warmed up is not bad at all. No worries for you but if you have free time on your hand cleaning the IACV and do an idle adjustment does not hurt.



As for the driving in the cold question. It's okay to drive when the car is cold but do not get on it at all. Remember that piston rings and other moving parts worn out quicker when the car is cold and not up to running temperature. It is however a good idea to start driving it when it's cold because it will warm up quicker, you wont waste gas letting it idle, and it also allow the transmission to warm up as well. Just DoN'T STEP oN IT. Drive easier and slower than your grandma and you should be good.

Wow. I NEVER knew about an IACV. My rpm s low and its off. Im going to try this! Thank you so much. And Im also going to check for any loose bolts.
Thank you ^.^

Try this link (idle adjustment)

If your rpm is low and not jumping around then a simple Idle adjustment may fix your problem. Do the IACV clean up too if you have time because you will have to sooner or later. I did everything to and it fix my idle problem a year ago and stay perfect up to now.

Follow everything in that article including warming up your car to operating temperature, disconnecting the IACV harness when doing the adjustment, and resetting the ECU (Unplug the battery for a few min if I remember correctly). VERY IMPORTANT.

 

My 90 gs sometiemes goes up to 3000 at first and then when it is warm it jumps from 900 to 1900 consistantly have cleaned and changed the IACV?

 

Hijacked so I don't have to start a new one...

My warm idle is perfect (700-750), but my question is this... is a fast idle of like 2000-2100 abnormal? I recently cleaned the iac and adjusted the idle a taste because it was a little low when warm. Now warm idle is perfect, but fast idle is a lot higher than it was before. (Was like 1500-1600 before now like 2000-2100). ???

I had that problem as well, where my car idled at 2000 - 2500 rpm when i first started her up. Clean your FITV as well. I only cleaned my IACV at first and saw no difference because i was to lazy to remove the FITV because it a little bit of a pain since it under the Throttle Body. Then did the FITV as well and like magic my car was idling at 1500 - 1700 rpm when i started her up in the mornings. I've have yet to have any problem with my idle anymore since i did FITV, IACV and Idle Adjustment.

 

Cool I'll give it a shot. Thanks.

 

Ok... So it seems I do not have a FITV since my GSR is a 1996. I can't see one on it either. Since my warm idle is perfect, is 2100 RPM too high for cold idle anyway? It never gets colder than like 45 around here this time of year, and I never start my car till like 10 or 11am when it's like 50. ?????

 

I had a problem with my car idling too high after I took it in for a smog cert.

I checked under the hood and everything looked good.

I disconnected the negative battery terminal cable to sort of "re-boot" the car/ecu and the problem went away.

It seemed like the smog shop let the car warm up forever and then the mechanic stalled it maybe five or six times trying to get it on the rollers; maybe that had something to do with it.

 

Our cars are meant to rev high when first started. As it warms, the ECU tells the motor to idle at normal RPM.

I understand that, it's just that before I adjusted my warm idle the cold idle was like 1700 and now it's like 2100. Just seems a little high to me. I don't know. ???????

Did you adjust your idle with the IACV disconnected?
