2001 elantra has been revving really high on cold starts, RPMs will stay at over 3000 till u switch it into drive or reverse, Never happens when engine is warm, had intake cleaned out, did not solve issue...
View 5 RepliesMy 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.
View 1 RepliesI have a 2002 Hyundai Elantra GLS with over 215,000 miles. About a month ago, I started my car and it revved up & down from 2 to 4 rpm. I took it to my mechanic and replaced the TPS, thinking it would fix it. What to do next. My mechanic fixes cars, but doesn't do it professionally. I don't have the money to take it to a dealership.
Now, after doing a tune-up and changing out other sensors the RPMs came down to 3 and will stay at 3 rpm when I start the car. When I drive it, it pulls on it's own without touching the gas pedal and is hard to brake. What else I need to fix or replace?
2002 Elantra auto trans issue.
We are experiencing NO throttle after the car sits over night. But Not every time. When I write "NO throttle" the car will start but will not increase rpms with pedal input/movement. Runs at idle only. After a few minutes, it picks up the pedal input and is fine until is sits over night, sometimes.
I have changed out the TPS and no change. The car has just over 80000 miles and otherwise runs like a champ. There is no check engine light or any stored codes. The cable rotates freely at the TB. I read in the forums that the TPS replacements can be suspect.
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!
View 3 Replies2002 Elantra idles high, 2.5 rpm, just when I start it up in the morning. The second I put brake on and put it into gear, it settles down and doesn't do it again until the next morning.
View 3 RepliesI've got a 2006 Elantra with 102,xxx miles. When starting the car, especially a cold start, it ignition is rough, sometimes a jolt. It runs fine after that. What might be the issue? FYI, i replaced the spark plugs in August or so.
View 4 RepliesPurchased my 2013 Elantra GT a few months ago and have been having a problem that had stumped everyone at the dealership. Thought I'd see who else is having it and what the thoughts are. To start, this is a 6SPD Manual Transmission.
Problem: Say you're at a stop and begin accelerating in 1st gear and then shift into neutral because you have to come to a stop again. When operating normally, the RPMs immediately wind down to idle. Well for me, about 15% of the time or more, the RPMs will take up to 10-15 seconds to wind down to idle. During this time, you cannot really shift into 1st gear because the RPM are too high.
The dealership has been working on this issue since last month. They replaced some parts and it is still doing it. They got diagnostic data and told me the throttle was sticking. No one could figure it out. Engineers got involved from regional, and it got pretty heavy as far as time. After several attempts at figuring out the problem and replacing things (which didn't resolve the issue), the engineers drove another new GT and found it was also doing it. So all of a sudden they said "it's normal" and closed the case.
Chances are, if other new ones are doing it, so is yours. I got second opinions from other auto shops who said it is not at all normal and that there may be a defect in the design. I've owned 4 Manual Transmission cars and I have never seen this before. If you're curious and have the 6spd manual version of this car, the easiest and quickest way to see this happen is accelerate in 1st gear to about 4000RPM and shift into neutral. Eventually, it'll get stuck and take a significantly longer time for the RPMs to return to idle. Usually when it finally happens, it'll keep doing it for several subsequent acceleration cycles.
,I have a 2004 Hyundai Elantra (stick shift) with about 104k on it. Was running absolutely great till about a month ago when I noticed that it was beginning to accelerate quite slowly. If I pushed it and got the RPMs up really high it would still pick up, but still not great performance. Also after pushing it a little hard there was a faint burning or smoke smell. Note, once it is up to speed say 60 or 70 it has no trouble maintaining such speeds. It just takes a while getting up to them. And if I really need to step on it the RPMs sky rocket with no real immediate increase in speed.
View 5 RepliesIt's cold here, around 40 below zero F. The 2007 Prius resists turning off - you have to drive around and try a few times. The computer read out screen is blank - no mileage chart or anything. The back up light is not working. The RPMs go high - is it supposed to shift internally when in drive?
View 9 RepliesStarting about a week ago whenever my car goes above about 2 thousand rpms I start hearing a faint high pitched whining sound, increasing to a more audible level as the rpms increase.. I've ruled out breaks and tires, which weer my initial thoughts, and I think it's something with a belt or the engine now. I have manual shift 2002 Hyundai Elantra.. The car still performs fine, but I have noticed a slight decrease in acceleration speed..
View 4 RepliesThe RPMs while driving does up and down. You can feel the engine doing this. You can watch the Tac go up and down. Whats the problem. We just brought a TP sensor but I say its a vacuum leak.
View 11 RepliesA buddy of mine has a late 2000 passat 2.8. He recently developed a bad knocking at higher RPM's. I took a look at it and it is coming from the bottom end of the motor (rod bearing, crank bearing?) He has no loss of power and the knock is not there at idle.
View 2 RepliesEarlier this week, noticed that my car was surging on its own; basically, if I came to a stop, I could still feel the engine, like it wanted to just take off. And if I would have taken my foot off the pedal, it would have done just that. Also, I knew the car had gas, but sometimes, when starting the car it would not start at all. I would have to wait about 5 minutes or so and add major gas to it with the pedal and then finally it would engage. And then the last thing was that when I would get to my destination and put it in Park, the RPMs would go up to about 1500 or so, maybe a bit higher and then stay there and go back down to about 1000, without me pressing on the gas pedal at all. So anyway, thought it was the throttle position sensor, so I had my Dad install a new one on the car. It was a pretty easy process and thought that took care of the problem.
The surging part basically stopped, so the new TPS took care of that, but then it still had problems with starting. Took it to a car repair place the next day and they changed out the spark plugs, said that they were causing a misfire in the engine. Also changed ignition wires and a new gasket. So after they were done, drove away and all seemed to be fine, but then went to the dentist and Parked and then the RPMs went up again. Tried to start it immediately afterwards and it wouldn't start again. Tried a few minutes later, added gas with the pedal and it did start. Took it back to the car repair place, they drove it around, inspected everything and everything checked out fine. (Yeah, of course!) Ok, so just thought maybe the repairs were taking a bit to take effect. But later in the day, wouldn't start again.
So next morning, took it to the Hyundai dealer. They looked at everything for about 2 hrs, and said that there was a vacuum hose that was leaking, so they put on a new clamp but everything else checked out okay. Ok, so now it starts fine every time, but today it did that high RPM thing again when I put it into Park. It doesn't do it every time, but the RPM will just go up randomly then go back down and go back to normal. Should I clean the IAC with some type of carb cleaner to get out any carbon deposits? Or could it be a bad MAF sensor? Not sure what the symptoms are of that. Everything else seems to be okay now except for the random high RPMs when in Park and sometimes at startup too.
It's a 2 WD, V6 engine.
When I married my wife two Fridays ago I also married in to her 2006 GLS Elantra.
It has pretty bad ticking which varies with RPMS, and how warm the car is, but is always there at lower RPMS. This has gotten worse the past for weeks, but that may be because she is longer into an oil change, and the filter isn't a great filter.
I am trying to do some research, but the search function appears to bring up items from all the different forums on the site.
Does this engine have solid lifter or hydraulic lifters? I am going to try a few oil changes with some seafoam and a quality filter first.
If that doesn't work how involved is it to replace the valve adjusters, or remove and clean?
I need to keep this car alive for a while, it is in overall great condition, 130k miles, everything works, doesn't smoke, doesn't leak oil, transmission is solid.
All that is wrong is the noisy valve train!
Can't run a/c rpms drop to almost 200 from 1200-1500rpms. Really bad when at at traffic light. I have to constantly press gas pedal.
View 5 Replies2004 Santa fe. Having issues with RPM running high. When car is started, RPM sits at 1500 for a few mins, then drops to 500. Seems to be having issues either getting into gear or staying. At any mph, car seems to surge and not feel like it's getting either gas or power. While on cruise at 55+ mph, car will also surge with RPM dropping 500, then kicking back in. This goes on every few seconds up to random times.
Had it looked at this past weekend at a dealer, and of course it didn't do it one time, after doing it for a half hour prior on the interstate. Tech found no error codes when he checked it as well. Car was fine for an additional 300 miles, then it started again out of the blue. Pulled out at a red light and I though I was going to stall.
Just got laid off so I'm trying to eliminate before putting a lot of money into it if I don't have to. 132,000 miles.
I have a 05 Hyundai Elantra 2.0L engine(Manual) thats been acting funny. There's a couple issues im having with it.
1. Not matter how far the gas pedal pushed down RPMs wont go over 2,500
2. Car surges and jumps back and fourth sometimes.
3. Idles around 900rpm
4. Sometimes when I take off I'm able to get around 40 mph, and thats where it tops out at.
5. Shifting into 1st gear feels a little spongy
6. Also it can go all the way into 4th gear without dying and the top speed will only be at 10mph
Things I've done so far.
1. Compression test cylinders all came back fine
2. Replaced TPS
3. Checked to make sure exhaust wasn't obstructed
4. I got a stethoscope and listened for the ticking for the fuel injectors and also got some fuel injector cleaner.
Three months ago I acquired a car from my brother. It was a 2001 hyundia accent gsi. The car had sat unused for 10 months and because of this I had to put some work into it. It has a new battery, new starter and new engine belts because one snapped upon start up the first times. I have also had the oil changed.
For some reason it is reving really high. At about 100km/hr it revs at about 4000rpm. I have talked to my brother and he said it did not do this before. It is changing gears because I can hear it and watch the rpm's drop before going back up. In 3rd gear at 60 km/hr it revs at about 2100 rpm's.
2004 Santa Fe .... 2.7 6 Cyl 4WD 150k miles
Recently I started experiencing RPMs surging upon startup and driving before my engine warms up. The problem has gotten worse to where I push on the accelerator the RPMs jump to 2700 and the transmission feels like it disengages. My initial thought was the tranny was going bad and slipping. I checked the fluid level in the T and found it was maybe a half Qt. low. I topped it off, but this had no impact on the problem. On a side note, I am able to use the manual shifting feature on the "His and Hers" Shifter and drive the vehicle without any issue. Transmission works fine in manual. The surging RPMs which only occur in Automatic mode, triggered the CEL and I got a code of P0123 which is high side voltage on the Throttle Position Sensor. I replaced the gray TPS with a new black one.
Upon startup the RPMS jumped to 3000 just sitting in Park. I disassembled and reinstalled figuring I had something bound in the throttle. After reassembly the idle went up to 2200, still no good! I reinstalled the original gray TPS and the RPMs, upon starting, RPMs were 1500 with the old sensor...still too high. I did reset the ECU twice during the process of putting in the new sensor and reinstalling the old sensor. Right now I found that when I disconnect the TPS electrical connector, the engine runs normal. It starts right up with the TPS totally disconnected and idles at 750 RPMs! It will not shift to 2nd gear though, when I try to drive it in Automatic Mode. I can however drive in Manual Mode and drive normal and shift right through the gears. Who needs automatic mode right?!!!
I had my Honda Odyssey transmission replaced 2 years ago. The past few months, in the first mile that I drive the car on streets in our neighborhood, the car goes into high RPMs (about 3000) before it seems to drop into gear. It does this 2 or 3 times then works fine after that. The "Check engine" light is now on all the time. Sometimes, the car does one other weird thing--the high RPMs end with the drive/D4 light flashing on and off like a blinker (even if I change gears to D3. When this happens, if I turn the ignition off it comes back on and seems to function fine. I have had it back to the shop that did the work about 4-5 times to get it right. I like the guys but each time they return it to me, the problem remains. I took a 2000 mile trip with it and with the exception of this persistent problem, the van worked fine.
