Sonata NF (2006-10) :: Idling And Power Loss - RPMs Will Drop Below 500 And Then Spike Back Up
Sep 15, 2014
So over the last few months I have been having more and more idling and power loss issues with my 2006 V6. When idling she intermittently will try to stall and the rpms will drop below 500 and then spike back up. A large percentage of the time I hear a loud whining sound while driving down the road and I notice that turning off the air conditioner will remove the sound at times.
***what I have done so far**
Idler Pulley
Belt tensioner
sepentine belt
cleaned MAF
Cleaned Throttle body
Throttle Position Sensor
Had car reprogrammed
So I pulled the belt off and checked all the pulleys and did notice some grittiness in the AC pulley (inner) and was wondering if this might be the issue. Attached is a video I uploaded, Video .....

It could happen once a month or 3 times a day. No pattern and never the first time I start my car for the day. But I will be running errands, park the tiguan, run into a store for 5, 15 or 30 minutes and when I get back in my car and start it up and go, it dies when shifting from 1st to 2nd. I know how to drive stick. This doesn't happen every time. I have called/taken it to the dealer 5 times and they have no clue because it never happens with them and I cannot predict when it will happen again. Also, on occasions, when i start my car, halfway through the day, the engine will idle really rough then the RPM's will spike and the car gives itself gas and my foot is definitely on the brake. These little issues are starting to piss me off, especially since the dealer just shrugs its shoulders.

I have an 05 corolla XRS. I just had a sport clutch put in about 1 year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop about 500 and I lose power for about 3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this.

I have a 1998 Accord, 4-cylinder VTEC standard transmission, 226,000 miles. Last fall I first experienced a problem with the car where within 5-10 minutes of starting the engine and driving, the engine seems to lose power/fuel and RPMs act as if they'll drop low enough for the engine to stall. If I take my foot off the accelerator, and reapply, the engine seems to gain power again.
Also, if I open the accelerator to full while the problem is occurring, it can occasionally "push through" and gain power again. Similar things will happen while stopped. In neutral, RPMs fall low and suddenly jump back up and then settle into normal idle. The problem never persists longer than 10 minutes within starting the car.
I took my car into a local shop that came recommended by a friend. They investigated a "check engine" light that didn't explain the problem and were never able to recreate the condition themselves. They replaced a few parts but lost the work order so I don't even know what they changed, but the problem seemed to have solved itself for a while. Recently it started up again and I would love to sort it out.

Recently I have noticed that when on a tune other than stock I am getting a surge at idle - my RPMs drop to around 621-630 then shoot back up to 660-675. On my stock tune my RPMs stay around 640-667 and don't cause the surge (felt as a shimmy so to speak). Is there anything else that causes a similar symptom? I attribute it to tuning due to it only happening when running anything but stock but could be wrong.

I have a 3.3L 2007 Sonata. Within the past month, after first turning it on in the morning, the RPMs shoot up to about 1400 and slowly come down to normal after about 5 minutes. It does this in park and neutral, when I put it into drive it goes down to normal. If I drive it for a mile and put it back into park and neutral, it idles at a normal RPM. If I turn the car off for ten minutes and start it up again, it idles normal at about ~850 RPMs.
After doing a bit of google research, a lot of sites say that this is a normal thing for a cold engine to do. However, the RPMs have never gone that high previously. The check engine light hasn't come on.

When your car is idling the rpms drop below 600rpm and you can feel like its going to stall but then goes normal. How do i fix this? Clean throttle body???
Also how hard is it to change the transmission fluid? Possible to do it at home?

I've had my 2000 Honda Accord V6 for about 3 years now and have had an idling issue pretty much since I purchased it. After driving for at least 50+ miles, and if its hot out it can easily have this issue as well, and leaving the car be for around 15 to 30 minutes, on start up the car drops RPMs immediately and dies. Multiple tries and it will do the exact same thing. Recently I found out a trick to make it work correctly which is revving the engine to 2000RPM for about 3-4 minutes, slowly dropping it down to 1500 RMP for around the same 3-4 minutes and finally down to 1000 RPM for an additional 3-4 minutes and letting off the gas. Usually after doing this the engine idles fine, car drives great. However, it must be noted that on Summer days with temperatures in the 85+ range, if I'm climbing (going up a hill for a long distance) the car might bog down on me, will not go above 50MPH and I have to pull off the side of the road for 45+ minutes before the car will run correctly again. This has happened about 3 or 4 times in the 3 years I've owned the car.
I would rather not have to rev the engine in hopes this fixes the issue each time so I'm wondering what could be the cause in the first place? I've replaced so many things including spark plugs, ignition coils, battery, idle air control valve, gasket, fuel pump, fuel pump relay and on. I gas the car up with Chevron gasoline, I've dumped in I don't know how many different fuel injector cleaners and have also tried Heet as well as Sea Foam cleaner. I've also had the car checked for vacuum leaks.
I've asked multiple mechanics if this could possibly be a vapor lock issue, but they all turn that idea down. They tell me that since the car is fuel injected this can't be the issue..but, I don't know, could it be the issue?

2006 Chrysler PT Cruiser. While driving, it seems at random, all gauges drop and stop working, no gas getting to the car, power loss. Sometimes lasts a split second, sometimes lasts up to 30 seconds. The car will even stall here and there, but usually not. Usually, power gets restored. But sometimes the car won't even start for an extended period of time. Of course, when the mechanic takes it for a ride it does nothing wrong.

I have a 2000 Neon with about 170K miles on it. with in the last 2 weeks it has been having a problem with acceleration. When i start to drive the RPMs will get up to 4 before it will start to move. Also when i am drive and need to pick up speed the RPMs will also go up to about 4 before it starts to pick up speed, but will drop back down when the speed goes up. I have found a little oil in the spark plug tubes and will be changing the seals out, and I have cleaned to MAP sensor as will. What is going on with my acceleration.

2011 Sonata GLS, 95,000 miles.
This just started yesterday. While driving, the RPMS suddenly drop off. Depressing the gas pedal doesn't command any power output, even if I floor it, the RPMS continue decreasing and there is absolutely no power. The only way to keep moving is to completely release the pedal and then depress it again.
The transmission has been serviced twice by me and shifts smoothly. Should I plug a scan tool in ?

well I don't exactly know if that's what I should call it... I was driving last night around 10 and I pushed the gas down 3/4 of the way or so to pass around this car but instead of downshifting and accelerating, it just revved up all the way, i kept hitting the gas and it was like revving it in neutral then it kicked back into gear... should i be concerned? It was fine the rest of the night but I wasn't driving it hard.

What's going on with my sonata. Its an 06 GLS 4 cylinder, 168k miles. I've actually had the problem before, and it lasted maybe about a week or two before the car went back to normal by itself. But a couple days ago it has returned. The car barely goes! All it wants to do is rev and not go. Coming from a complete stop is the worse, as it takes me forever to get up there in speed. I already feel like a danger on the road by sometimes not being able to keep up with traffic. Once I get up there in speed I'm able to keep it at that. I thought it was maybe the spark plugs last time, so I changed them, but that didn't seem to be it. I know the car has electrical issues, now I'm just thinking its that since its done it before and went back to normal. I took a video to get a better idea of what its like. [URL] ....

I was cruising on the highway and tried to accelerate and no more power. Could feel engine losing power. After I shutdown the car and start again, car was fine.

In the past month or so I've noticed some weird behavior out of my car. 2006 Mini Cooper 130K miles on it (still going strong!!) Automatic.
Scenario 1 - Driving in D accelerating at a normal pace (read, not gunning it) the RPM's spike rapidly from 3K to 4K and the car almost sounds like it's redlining. Once it hits 59-60 MPH it drops back down to 3K RPM and the rest of the acceleration is normal.
Scenario 2 - Cruising on the highway at about 70+. Normally start taking the foot off the gas to slow down with traffic and when my speed drops to about 60 MPH the RPMs spike again from around 3K to about 4K. When the car gets below 60 MPH the RPMs drop again. If i let the car come to a stop the RPMs decrease normally without any other spikes.
Scenario 3 - Driving in sport mode (yeah buddy) around 20-30MPH it almost feels like the car is not upshifting and the rpms go crazy. jump from 2500 to about 4-4500 and finally the car lurks forward.

After I fill my 6 cyl 2004 Hyundai Sonata (280,000 km), the engines starts, then stalls. I can only get it to work by keeping the accelerator pushed to ensure sufficient rpm's. If I remove my foot from the accelerator, the rpm's drop to zero.With the engine revving, I put the car in drive and 'lurch' away from the pump. After that, everything is fine. It starts up properly … until the next fill. My mechanic is mystified and I am frustrated.

My daughter's 2007 Sonata 4 cyl (88k miles) has an occasional power steering loss. It has only been noticed right after slowing down from highway speed. Total loss for a few seconds then comes back. No dash lights or noises, just steers like an old classic without power steering - then can.
This is kind or a repeat post from another individual but he had a V6.
SBR711 recommended replacing the Harmonic balancer and I am inclined to do so but parts guy at Hyundai said that typically is not an issue in the 4 cyl model. So he does not keep item on hand.
Fluid is fine, clean and proper level. No screeching etc..

I've got about 80K miles on my '06 Sonata and the weather conditions were on the very wet side.
At first I thought I heard a squealing sound which I just credited to either a radio or windshield wiper sound while cruising through some twisty coastal roads. The rain was coming down pretty good and a small amount of standing water of already on the road.
As I continued my drive I began to notice an occasional loss of power steering for a split second through some turns accompanied by that same belt squealing sound. At the same time the battery light also came on for a split second which indicated to me possible engine failure for a split second. Even though it was for only a split second it really freaked me out to think I could end up crossing the center lane or over into the ditch. I then slowed my pace for the rest of the trip. When I stopped for gas I popped the hood and things appeared to be normal and with plenty of power steering fluid.

I have a 2007 Sonata GL. So tonight after work when getting into car to go home I noticed my CEL came on, also as I was driving at low speeds/rpm I noticed the car really sounded like it has a diesel engine in it. At higher speeds on the highway I noticed it has some loss of power and the diesel sound went away. CEL stayed on.
The CEL light I am pretty sure is the OCV which I havent replaced yet. So my question is: Can the OCV cause the car to sound like a diesel and have loss of power is that caused by something else?

My 2006 Sonata V6 (88k miles) has an occasional power steering loss. It has only been noticed right after slowing down from highway speed. Total loss for a few seconds then comes back. No dash lights or noises, just cant steer - then can. Did all required maint. until 60k then just oil changes by me. Have read other forums about fluid flush, but that was for noise and I don't have any noise. This has happened with and without the Electronic Stability Control turned on. Other than that, runs great. MPG is about 25 or so (wish was 30 or so).
