Elantra XD (2001-06) :: Stalls While Driving Frequently / RPMs Drop For A Split Second
06 Elantra Limited, 96,xxx miles. When I'm idling at a light or something, the Rpms drop for a split second, almost to the point of stalling, but recovers. Happens in a split second. Does the same thing even when driving, but does it more frequently when idling. It even does that when I first put my foot on the throttle to accelerate from a red light.
I've cleaned the throttle body but it still does it. I've taken it to 3auto parts stores. One said that battery was bad. The other said the battery is fine but alternator is producing low. The last said both are fine.
Elantra XD (2001-06) :: 2005 - Loss Of Power On Acceleration / RPMs Surge Up Very Slowly
So my 2005 elantra 2.0 CVVT has 189k on it 1 owner.
I got a check engine light one day and i read the code. Came out to be 02 sensor code bank 1. So i order a denso o2 sensor and replace the part.
I drive the car for about 400 miles to reset monitors and get a check engine light. P0420 cat code. At this point the car drives with normal power and pickup.
1000 miles later my car has lost power. It doesn't have any get up or power when driving normally. I take the car to my local shop and they recommend replacing front cat. I replace front cat, same issue.
At this point i'm not sure if it is a transmission problem or maybe my 2nd cat or something else?
On the freeway if I put my pedal to the ground the rpms surge up very very slowly,
Also seems like the car doesn't shift till around 4k rpms, seems like previously it shifted sooner.
Elantra MD (2010-15) :: RPMs Drop / Car Bogging Down When Shift Into 4th Gear
I am not sure if it's my imagination or not, but my car seems to be running differently lately.
When the car shifts into 4th the Rpms seem to drop kind of and the car seems like it is bogging down. Not extreme, but I don't remember this when I first got it. It's like I really have to accelerate when it shifts into 4th or I cannot pick any speed up.
Is it because the motor is now broken in? It has right at 8,000 miles now. It's due for an oil change, but I wouldn't think that would have anything to do with it !
Honda - Odyssey :: 2005 - Drop In RPMs At Approximately 30 MPH
I have a '05 Honda odyssey that has recently started showing drop in rpms at approx 30MPH. At that speed, I see that RPM suddenly drops from 2500 to 2000, pressing on gas really hard, triggers downshifting of gears and everything comes back to normal. I suspect some issues with how gears are being shifted...
View 3 RepliesExplorer :: 2001 Ford - RPMs Drop To About 4 To 500 And It Stalls Out In Reverse Only
I own a 2001 Ford Explorer and have had the regular wear and tear but this problem has me stumped. A few months back I had to change the auto body gasket because the truck would not go into gear. After doing this the truck ran fine, I also changed the tranny fuild and filter. The other day i went to back up into the garage and the truck stalled and died out. it started right back up and it runs fine in all other gears. (P,N, D, 1,2, 4x4 high and low) and the over drive is working fine. when the truck is cool and hasn't ran in a while i can start it and the rpms stay at about 1000 th 1200 and the reverse works great. Now when the eng. heats up to normal and i put in in reverse the rpms drop to about 4 to 500 and it stalls out and dies. I have cleaned the mass air flow sensor, the throttle body, and the IAC valve but still dying out. Im thinking it may be a vaccume leak or the IAC is bad and cleaning just wont do the trick. I have also read that it may be the back up light wiring that hooks to the tranny may be shorted out.
View 4 RepliesBuick - Regal :: 2001 - RPMs Will Drop And Car Will Jerk Forward
I have an 01 Buick Regal GS, 82k miles. When I baught the car it had 80k miles but had been sitting for a while. I put in a new battery and changed the oil as soon as I got it. When accelerating the RPMs will go up but the car won't accelerate as fast. The RPMs will drop and the car will jerk forward. And then accelerate better after it is warmed up a bit. I thought to give it some time and maybe it will go away. 2k miles later it is still doing it. What it could be?? I would like to see if I can fix it myself.
View 3 RepliesHonda - Odyssey :: 2001 - Car Goes Into High RPMs (about 3000) Before It Seems To Drop Into Gear
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.

the wife's '01 Excursion has developed a new idling quirk. While sitting, it will briefly drop rpm's. You can hear it, and see it on the tach gauge. No other noises or problems, except for the brief drop in rpm's.

I ran out and test drove a new to me 2001 F350 7.3L tonight. Everything seemed good, until I got back from the test drive. I pulled in and was sitting there with it idling. It seemed to idle fine, then a very small miss and very small shimmy then idle fine again; then another small miss and another shimmy. It continued like clockwork. Every time it seemed to miss and shimmy, the RPM would drop just a little, but not much. Does an ICP sensor sound like the problem, or maybe something more serious? 2001 F350 7.3L with 235,733 miles new trans, turbo replaced at 150,000 something miles. No blow by. Idled fine before driving, also drove fine. It doesn't seem to surge when idling, just kind stalls and shimmys for a split second then idles fine for a few seconds.
View 1 RepliesElantra XD (2001-06) :: Sluggish And Shaking - RPM Drop Down
I have a 2003 Elantra, which I've had for several years, and love greatly. Recently though, she's been giving me problems.
When it first started happening, about 6 months ago, it seemed that she was simply sluggish, and wouldn't accelerate as well as normal when I pushed the gas.
It has gotten worse from there, within the past 4 months, sometimes when I turn her on, she idles very rough, and the entire car shakes. Originally when this started happening, if I turned her off and back on, she would run smoothly again. Unfortunately that's no longer the case.
If I attempt to drive anywhere when she's acting up, pushing the gas makes the RPM drop down, and she doesn't move. This has caused a lot of problems at stop where I'm turning onto a busy road. Occasionally when I'm driving around, her RPM drops far below what it should. For example, she frequently drops down to 700 RPM when I'm driving 35 mph... normally when going that speed, the RPM is about 2000.
Most troubling to me is the fact that the engine turns off on me without warning sometimes. I've had her do it when I'm at a stop waiting to turn, at stop lights, and dangerously, even when I'm slowing down through traffic or getting ready to pull into a parking spot.
I've tried multiple things, fuel injector cleaners, replacing temperature sensors, and I've checked all the valves, wires, and hoses. I've had it attached to a code reader and of course she never acts up while it's attached.
Elantra XD (2001-06) :: 2002 - Delayed RPM Drop Between Shifts
My nephew's car is a 2002 Hyundai Elantra GLS manual. His RPM's hang when he shifts and it is a pain to shift.
I took it to the dealer and had them do TSB#04-36-011 Delayed RPM drop between shifts. This TSB supersedes TSB 01-36-025. Here is a link for the newest TSB : [URL] ....
The TSB Basically tells them to erase ECM adaption values. Then, you update the ECM with new FUEL cut-off logic. When we drove off the dealers lot the delay was not better, just different.
After driving it for a day or two we saw improvement. Now when you push in the clutch the RPM's go up slightly for a second to burn off the gas then the RPM's drop faster than before.
Elantra XD (2001-06) :: Sudden Drop In Mileage And Hard Shifting
All of a sudden my fuel consumption dropped from 28mpg as read from the computer display in the dash, to 21mpg. This was not a gradual drop, it was at 28mpg one day and 21mpg the next day. There is no service light on, do these cars produce codes that don't trigger the service light?
A few months ago the vehicle was getting stuck in various gears and lunging, this was from battery corrosion dripping down and eating away at the transaxle range sensor. I cleaned up the battery and replaced the range sensor and the vehicle was driveable again. It re-learned the shift timing and seemed to be ok, then about a month ago it seemed to be forgetting the learned shift positions after sitting over night, I replaced the battery, thinking it was in a marginal state where it would forget the program while sitting. The shifting is still hard sometimes but this seems to have worked but, now my mileage is horrible.
I thought I'd just change out the oxygen and air flow sensors but, then looked at how much they cost now, and realized this would be some costly trial and error. Is there a methodical way to troubleshoot this issue, any way to pull the sensors and measure them?
Hyundai - Elantra :: 2005 - RPMs Going Higher Than Normal While Driving?
So I have a 2005 Hyundai Elantra, it is a manual transmission. I was having problems with the rpm's going higher than normal at random times while driving, then I noticed that the fluid in the clutch fluid reservoir was low. I determined that to be caused by a bad clutch slave cylinder that was leaking fluid. So I replaced the slave cylinder and that seemed to fix the problem, but now I am noticing that the car lacks power when I'm going up any sort of hill or trying to accelerate faster than normal.
When going up a hill the rpm's will go up and I have a hard time maintaining my speed. When trying to accelerate fast, as in pulling out in front of someone or similar situations, the car seems sluggish and it seems like I need to shift because the rpm's are high but I'm not going fast enough yet for the next gear.
This sounds like it would be some sort of problem-related to the clutch going bad or could the leaking slave cylinder have damaged the clutch. Or does this sound like more of a different problem, maybe something with a fuel filter or something?
Elantra XD (2001-06) :: RPMS Goes Up And Down While Driving
The 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.

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!
Elantra XD (2001-06) :: HIGH RPMs At Cold Start

View 5 RepliesElantra XD (2001-06) :: Spongy Gear / Idles At 900 Rpms
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.
Elantra XD (2001-06) :: 2002 - At Start Up Revved Up And Down From 2 To 4 Rpms
I 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?
