Elantra XD (2001-06) :: High Idle / IAC Motor Revving Up And Down


May 4, 2009

I had some problems with my Elantra and I fixed (or tried to) them all this weekend. I needed a new IAC motor, the motor was reving up and down and I tested it, then changed it. I needed a fuel injector and changed that. I needed a lower thermostat housing and changed that.

These changes resulted in the following problems. The vehicle now revs at a high idle all the time at approximately 3000. What are the causes of this?

I know that when I was burping the coolant system (changing out all the hoses and the thermostat housing) I got antifreeze sprayed all over the top of the motor.

Here is the problems that I have now. Didn't have these before.....

The engine idles at or about 3000 rpm. Constant from startup until shutdown. It idles down when you shift it into gear but that is because of the strain on the motor with the brake used.

The transmission is now having problems shifting from 1st to 2nd. I checked the fluid, its good. There is however antifreeze on top of the transmission by some sensors. Do these sensors have anything to do with the shifting?

Elantra XD (2001-06) :: Engine Temp Too Hot When Revving But Cools Down At Idle

My engine temp gets too hot when revving the engine but cools down at idle. The top rad hose is hot and the bottom rad hose is cool. I'm suspecting a stuck thermostat?

Elantra XD (2001-06) :: P0519 Idle Erratic / RPMs Constantly High

My friend was having trouble with her 2001 elantra. Her idle was erratic and her RPMs were constantly high. we checked every where for a vacuum leak but could not find one in any of the lines. We went on to switch out the idle air control valve, the throttle position sensor, and even cleaned out her throttle body. we threw up our hands and sent it to a shop. Come to find out there WAS a vacuum leak. apparently in the air idle control valve sensor there is a gasket that seemed to be missing. I of course didn't think about replacing a gasket when I replaced the sensor because I never saw one there.

Hyundai - Elantra :: 2002 - Revving At Idle

I have a 2002 Hyundai Elantra that is exhibiting some strange behavior at idle.It wants to rev from 1500 to 3000 rpm, then back down, over and over again, every two seconds or so. This does not occur when the car is in drive or reverse; it purrs along at a consistent 1200 rpm.It all started with overheating and a water pump change, which was completed and reassembled.Then on startup, we began getting this revving. We double and triple checked the timing belt. We sprayed plenty of carb/choke cleaner in the areas of the vacuum hoses searching for a leak to no avail. Whenever we hookup the OBD code reader, there are no codes.Why does my car want to challenge everyone to a drag race, and what is causing this?

Tacoma :: 1999 Truck Quits At Idle After Revving High

I have a 99 tacoma with a 3.4 L automatic with 160,000 miles. For the past year my truck will idle rough and quit after revving high. After driving around for a few min its fine until I accelerate hard and get it up to about 4 to 5 thousand rpms. I recently changed the timing belt and accidentally got it about two teeth off. While it was like that, it didnt have much power and it was very loud, but it didnt have the problem. Once I fixed it and got it timed right it started having the problem again.

Elantra XD (2001-06) :: Revving Up To Around 2 - 3k Rpm Upon Startup

My car has been revving up to around 2-3k rpm upon startup... the mechanic says it's a faulty idle air control valve. He tried to clean it but to no avail--the car still revs up occasionally.

I can't find the IAC valce in the Hayne's Manual. Might it be called something else? The idle speed control actuator, perhaps? Is this is job for an industrious do-it-yourself?

Chevrolet - Montecarlo :: 2001 - Revving In Idle / Chugging Along

I have a 2001 Monte Carlo that I absolutely love. The check engine light has been on forever, despite repairs that should have turned that light off. Just recently, my car has started to gain RMP while I'm stopped or going anywhere between 0-25 miles per hour. This also makes the car physically shake and jolt. Very unfortunate. I turn it on to drive once more and then my check engine light flashed and beeped at me. I thought about waiting to take it in until Monday, but now I think it is best to bring it in now.

Yaris/Scion & Vitz :: Toyota Echo Motor Start To Idle Really High For A Couple Of Minutes

I've always find solution to solve my little issues with my Toyota Echo 2004 Hatchback. Since last summer, my car seems to have a lot of problems to idle well with the fine rpm. Here are all the events :

-it all started last summer, when the motor would start to idle really high for a couple of minutes, before getting back to normal. When this happened, a p011 check engine would light up. I switched to synthetic oil, and it greatly reduce the number of time this happen, but it didn't solve it entirely. It usually happens when the motor is warm, but still not hot.

-Only once, during a long ride, I got a check engine. When I left the highway, my motor wouldn't stop idling high. stop/start the motor wouldn't change anything. I checked the check engine codes, if I remember well : p011, p016 and misfire. With a friend, we checked the crankshaft sensor, and it was really dirty, so we washed it, and it solved the problem! A few days after, I also change my spark plug because they were starting to be old.

-A few weeks ago, I started my car and it was idling high as usual to heat up faster (it is winter now). But then, the rpm suddenly drop really quickly. The rpm was really low for may be 2 seconds, and it nearly chokes, but just before it went up back to normal. Then low/high/low/high until the motor was hot. No check engine. I disconnected the battery for a few minutes, and when I reconnected it, the problem was solve. I also checked the air filter, but it wasn't dirty.

-Then, sometimes when I start my car, idling is fine but suddenly at a red light the motor start to run really low with a lot of vibrations and a bad smell. Stop and restart the motor solve the problem! But only until the next red light, or until the motor is warm enough. Still no check engine.

Elantra XD (2001-06) :: Occasional Thumping Noise From The Rear - Motor Mounts?

Have a 2005 Hyundai Elantra 2.0, 4-dr sedan, with 120,000 ,miles on it. Since we bought it in 2007, there occasionally was a thumping noise, seemed like from the rear. Well now, I have just about changed everything you can think of on this engine. But when I put in gear, or am stopped at red light the cars idle is terrible, runs very rough. Someone said maybe the motor mounts? If so how can I tell, approx cost, and are there only the two?

Prius (2004-09) :: 2005 - Motor Revving To 3k - 4k But Not Moving

I have 160k on my 2005 prius. When letting off the gas peddle in DRIVE the motor is reving up to 4k with out the trans kicking in and moving the car. I have replaced the 12v bat, cleaned the t-body and mass air sensor.

I took it to the local toyota dealer for a recal and now they have had the car for over a week. I am being told it is the floor peddle sending a false voltage to throttle body. I highly doubt that this would not make the care go and not just idle up to 4k.

Elantra XD (2001-06) :: Idles Really High For A While After Start

So, among other things my 06 Limited is acting a little weird when I start it up. If it's cold, as in hasn't run in a few hours, not so much temp, it idles really high for a while. I wait for it to come down under 1000 before rolling out. It makes a funny noise too. Sort of a tick-tick-tick with a little whine behind it. What it could be? How much it'd be to get it fixed? I'm past my 100,000, 107,000 to be exact. Of course the issues pop up after the warranty is up!
