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?
My 2004 hyundai elantra is revving up on its own up to about the 1 rpm area when I stop at stoplights. I am very worried that it is going to be a huge cost to get repaired.
View 1 RepliesI 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?
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?
View 5 RepliesDriving car auto slips into neutral, car keeps revving until stopped lever put in neutral then into gear drive off again. Thats mothers version of what happens. This happens once a week for last six..
View 2 Replies2002 Elantra engine is revving up to 3000 rpms when in neutral or park. I changed the Throttle Position sensor and it went right back to revving up. Code read P0121. What might be causing this? Seems like I get one thing fixed and then another code shows up..
View 2 RepliesMy 05 beta 2 (CVVT) lifters are a bit noisy. On startup its a bit loud but quiets down after it warms up, but its still there. Kinda sounds like it needs a valve adjustment. Not sure if there is another way around the noise. Like a full synthetic or a heavier weight oil?
View 2 RepliesI replaced my GF's water pump, timing belt, tensioner and roller on her 05 Elantra. WHen I started the car up I can hear a loud whine from the belt.
Everwhere I searched I read that it's too tight.
But in this video: [URL] ....
At around 9:11, when the guy starts the car it's the same exact whine? Is this normal or something with a brand new belt? Or did he tighten it too much? Or is it because her timing belt covers are missing the rubber grommets, and there is a HOLE in the side of one of them. So am i getting the full brunt force of the timing belt?
2003 elantra when I start the car the belts squeal for about a minute, then whatever I do they start squealing again- turn on headlights, roll down windows, steer the car, turn on ac, anything starts the squealing again. I have had all new belts including timing belt, water pump, etc and it is only getting worse by the day.
View 2 RepliesRecently, when I start my Golf 2.5 DSG it has been revving a little loud or rough. It usually revs at under 1k at idle, but when starting up it revs at around 1500 until I put it in drive and release the footbrake.

This just happened recently this winter. After a cold startup I hear a constant hissing noise (for lack of better word) coming from under the hood for about 5 minutes .
This is NOT the kind of sharp noise that you would hear from a loose power steering belt but it is definitely coming from that area (towards the passenger side close to power steering belt/alternator), though I could not pinpoint the exact location.
Everything seems to be working fine and after about 5 minutes it goes away. I am not missing any fluids and don't experience any other symptoms.
I hear a bit of exhaust leak noise from engine compartment only at a cold startup, it goes away in seconds. I am 700miles from home. If it's a nonessential fix i will drive home before fixing, or, if an easy gasket replacement, I have two more days here, and tools,garage, and competent support to diy the job.
View 4 RepliesAutomatic trans. When jumping off a stoplight or sign, I accelerate up to between 2-3,000 rpm and lift off gas. Tach stays there, say at 2,500, and slowly goes down to normal 14-1500rpm while coasting.
Also noticed deep growl when lightly pressing accelerator to keep up in traffic. Overall, in-city driving this automatic feels like a manual being driven constantly between lowest gears when my foot is not on gas. Sometimes I need to accelerate even going down a moderately steep hill. Does not happen on highways. And yes: I *am* in Drive - not shift-tronic.
Is this just how these Elantras drive/sound? Car has just over 38,000mi. 2015 Elantra SE 1.8L ...
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?
View 8 Replies2006 Hyundai Elantra. RPM's go flying everytime it's fired up. RPM's will drop once it's put into gear, reverse or drive and runs just fine afterwards. If it's not affecting how it drives should we just let it be? Is there anything to be concerned about?
View 2 RepliesI drive a 2004 Hyundai Santa Fe V6 2.7L with a whopping 274,3xx miles on it. I've had it for about 6 years and it has been a great car for the most part. The water pump was replaced a couple years ago and the battery was replaced a year ago.
It started having issues a few months ago. It started out having difficulty starting, and shortly after it would start it would rev up as if you were accelerating even if my foot was on the brake. I took it to the shop and they checked the head gaskets, battery, transmission, alternator (I think?). Came up with the idea that it may be the air intake valve. It's the thing that controls how much the blade opens when you press on the accelerator. Well they took it out and said it was the dirtiest one they had ever seen. They cleaned it, because no one in our area had a replacement, and my car seemed to be acting better. It would still rev occasionally and would have trouble starting but not nearly as often as before.
Fast forward to now (a month later) and my car is revving higher and for longer than it ever has and has started stalling, and not starting more frequently. It usually stalls after it has been revving when it cant release or go forward (ex. when applying the brake or while in park.)
What the heck is wrong with this thing?? No one seems to be able to figure it out and it it so frustrating, not to mention dangerous! It stalled in the middle of me making a turn today so I was literally sitting in the middle of oncoming traffic with a dead car.

Car is a 2004 santafe 3.5l automatic. symptoms are phantom revving up to 3-4k in park without me doing anything, sometimes car is hard to start, idle is very erratic/doesn't want to stay running. other times it starts and drives perfectly. from what i can gather this is some sort of malfunction in the electronic throttle system, and from searching people say "inspect ETS system", but i'm not sure what this involves. i unplugged every sensor i can locate in relation to the throttle system, cleaned them with electronic spray cleaner and put some di-electric grease. reset the ecu through battery disconnect, and problem came right back. local shop pulled the codes and said it'll be about 1200 for a new throttle body, and that the dealer has to reset it say what.
is there anything i can do with this sans bringing it to the dealer? i'm not even sure it would make it that far, driving home from the local shop it was in limp mode and i could only drive about 30 mph, and barely made it up hills. probbaly take me three hours to drive to the nearest dealer lol.
i replaced the accelerator pedal sensor about a year ago, and it also threw a code for throttle position sensor about a year ago also.
I have replaced the MAF sensor, TPS sensor, and fuel filter. Like the title says...if I rev the engine ...as soon as I let off the accelerator the engine stumbles and almost dies...then settles back down. I initially pulled codes PO121 so I replaced the TPS. PO103 so I replaced the MAF sensor. PO112..did not address directly as I assumed the MAF was causing. PO1123...again I hoped the parts I replaced would solve the problem. Initially the engine would just drop out while driving just for an instant and then be fine...also I had the 4 codes mentioned above. The only code that has returned is the PO121. I just got done replacing the fuel filter and things seem to be worse.
View 1 RepliesI 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.
View 4 RepliesI am after to find which USB cable and software can be used on my wife's ... 5/05 v6 Santa Fe to check the error codes. The car is revving up and down when cold and lacking power when warmed up, I'm guessing it's a sensor but I need to find which one.
View 1 RepliesI have an '01 gti glx that I just swapped a motor into. I got the motor out of an '01 jetta glx, exact match AFP engine code.
I get cylinder 2 misfires mostly (high number) but I also get 5 and 6 intermittently as well as a P0300 code.
Sometimes I also need to hold the gas down just to get it to start even after the crank sensor.
The engine idles sometimes at 600 rpm but drops and nearly stalls after revving at all.
What I've tried so far:
working cam sensor from my old vr
brand new crank sensor
brand ned wires/plugs
new fuel filter
swapped injectors of misfiring cylinders from old motor
lined up the timing 3 times now and its still perfect
I know the coil pack works because it was on my old motor, which ran fine, just leaked oil.
