Camry 2012+ :: RPMs Fluctuate A Little On Cold Start - 2013 SE 2.5L
Noticed that when you first start the car it makes a very strange noise? Almost as if the motor was running dry for a few seconds and the rpms fluctuate a little... Is that normal? I've only recently owned my camry and was just curious. 2.5L motor.

After start up it bucks and surges, acts like it is starving. RPMs fluctuate. Once it fully warms up and driven a little bit it clears and runs normal. This all began after the alternator went bad and battery warning light came on. Batteries never went completely dead, but could low batteries effect sensors or control module. This morning it was difficult to start, not low battery problem, but a lot of bucking and black smoke. I changed the fuel filters and a little better. New air filter last week when alternator was replaced. No codes have appeared.

Lately, my 1990 Integra has been idling VERY low. Some mornings, while idling at a stop, the rpms fluctuate up and down to the point where it almost dies. Is it just cold? I live in coastal San Diego, so it's not freezing here. This morning, had to keep my foot on the gas to keep the car from stalling before getting home from dropping son off at school. It died in the driveway. Started up just fine right afterwards, but idled down to nothing. Now it idles okay, but at a pretty low rpms, like usual. NOW, the battery, a SEARS Diehard Silver, is near the end of its usable life. Prorated 84,000 mile replacement warranty, but I have had it for 8.5 years and have 1 82,000 miles on it. YES! I have been meaning to replace it, as it is leaking some nasty stuff at the terminals, but wonder if the weird idling is a symptom of something else, since the car still turns over.

i got a problem with my 96' 2.4 auto cavalier. It idles really rough at idle. I've replaced alternator, battery, idle air control valve, intake, plugs, and the fuel pump in the last year and a half. I've noticed that the rpms will fluctuate between about 625-675 when it's idling rough. About once every 11 seconds the car will rev up for a moment and will idle smooth but then it idle rough again. Every one in a while it will throw trouble code p0200 random multiple cylinder misfire.
View 14 RepliesSanta FE SM (2001-06) :: RPMs Fluctuate And Car Stalls At Stop
I have a 2001 Hyundai Santa Fe LX with 214,000 miles on it. In general, I am having two problems which are most likely related. I would like to get opinions on what is causing the problems, how to fix the problems, and what the cost might be for the fix. This is an older car and I don't want to bring it to a mechanic to just do searching.
1. RPMs fluctuate quickly at slower speeds in town stop and go traffic and while parking in Drive or Reverse. Fluctuation can be between 1000 to 2000 and 3000 RPMs back and forth.
2. Car stalls while sitting at stops when in Drive. When car stalls, RPMs have suddenly decreased to 0 (zero).
3. RPMs fluctuating and car stalling typically occur after I have made my first stop and have turned off the car.
There is also a Check Engine Light Code: P0304, Cylinder 4 Misfire Detected. I changed the vehicle speed sensor a few months ago.
Here are the details of what has been happening, when it happens, and what I have tried.
- When RPMs fluctuate, the car slowly accelerates and slows down and I can hear revving high and low. This happens when the RPMS fluctuate just a few RPMs around 1000 and when the RPMs are fluctuating up to higher RPMs.
- After the car has been driven for about 45 minutes and car is at slower speeds, RPMs will fall to zero while at stop and in Drive, and the RPM fluctuation will begin.
- RPMs jump to 2000 or 3000 and stay there but do not fluctuate when car is put in Park and Neutral.
- When car is in Park and at 2000 or 3000 RPMs, car takes a few extra seconds to turn off.
- Car accelerates without pressing gas pedal and will accelerate up to 40 mph.
- Car will sometimes lurch at slower speeds of 15, 25, and 35 mph when RPMs are fluctuating or when the gas pedal is pressed.
- When RPMs are fluctuating and at 1000 or higher and I am pressing the brake to slow down, the car fights in Drive and in Reverse.
- RPM fluctuation does not occur at interstate speeds.
- A couple days ago, when I was at interstate speeds of 60 to 75 mph and pressed the gas pedal, the car would stutter and jerk.
- RPM fluctuation and stalling primarily do not occur when the car is started at the beginning of the day or when the car has been off for several hours.
- Twice In the last week the RPM fluctuation and stalling occurred even after car was not started for several hours and after only about 5 to 10 minutes of driving in town stop and go traffic.
- Sometimes car stalls when I'm at a stop and slightly press the gas pedal to start driving.
- There are times in town traffic when the car is operating normally and is at 750 RPMs at stop, then the RPMs suddenly decreased from 750 to 0 (zero) and the car stalls.
- From Neutral, sometimes when I simultaneously put the car in Drive and press the gas pedal either by feathering or forcefully pressing pedal 3/4 to the floor, the car would have a delayed reaction to accelerate but would not shut off.
- After car has stalled, if I try to start it right away, the car cranks but does not start for about 5 minutes.
- The time between stalling and being able to get the car to turn back on has increased over time from starting up at first crank to not starting for 5 minutes.
- If I let the car sit for 3 to 5 minutes after it has stalled, the car starts up but takes a couple seconds to start while pumping the gas pedal.
- Issues have been happening since November but are getting more frequent.
- Stalling is happening more frequently and within minutes of each other.
Civic - Honda :: 1998 - RPMs Fluctuate At Idle
My 1998 Honda Civic DX's RPMs are fluctuating during idle. I start the car and it is normal for about two seconds. I am assuming around 800 rpms (I don't have a tachometer). Then it jumps drastically higher, then lower, then higher, etc. Earlier tonight I replaced the throttle body gasket, replaced the spark plug wires, and cleaned the fuel injector cleaners. I took off several things in the process. I think the problem originates from taking apart the throttle body - not the other replaced parts. I have a manual 2-door 1998 Honda Civic DX with a 1.6L engine (D16Y7 engine to be exact).

Golf IV / Jetta IV :: 2003 - Jerk When Accelerating / RPMs Would Always Fluctuate
I have a 03 jetta 1.8t and for as long as i can remember my rpms would always fluctuate whenever ever i was idling and then there would be sometimes where i would be accelerating and i would have no power and then all of a sudden it would kick in kinda jerky like. About a week ago tho for some reason my car would just all of a sudden die when i would come to a complete stop and it did it about 5 times that day but when it died it would start right back up fine. I've been having this problem for quit awhile.
I have gotten told maybe coilpacks, n75 valve, o2 sensor, MAF i ended up buying a can of sensor cleaner and cleaned out sensor but that doesn't look like it did the trick. i have also noticed when i drive her pretty hard sometimes the rpms will fluctuate a lot more frequently than normal there also times where when ever i start in 1st gear it doesn't feel like i have all the power have than usual and I've noticed it only feel like that in 1st and second gear sometimes.
Toyota - Corolla :: 1996 - RPMs Fluctuate From High To Low In Regular Intervals
RPMs fluctuate from very high to very low without me doing anything. It doesn't do it all the time, so far its happened 4-5 times in the past 3 days. I first noticed it when driving, I took my foot off the gas to break and it started doing it and once I hit the gas it stopped. It seems to be getting worse because today I put it in the park and when it should have jumped into idle it started and even when I hit the gas it didn't stop. Like I said the RPMs fluctuate from very high to very low in a few seconds regular intervals.

After I got done with all of this crap on my Ranger, I noticed that it was driving great! But...today I was on my way to school and BAM! My engine idle started hitting (presumably because I do not have a tachometer) about 3000RPM and lowering down to about 2500RPM and from there, every time I am not in gear it decided to fluctuate between 2500RPM and 3000RPM. Crazy style too.
Now, I got to school, and getting closer to it at a stop light the truck basically died. It was almost at 100'ish RPM. I gave it gas, and BAM. I hear a continuous hissing noise from under my hood. Haven't diagnosed it fully yet because I just got home and its 12AM.
Now, every time I stop at a light or in traffic or whatever it may be, I have to give it gas every other second, like a small push on the pedal, to make sure the truck doesn't die. Also, every time I am out of gear and my RPM's are at an 'idle' state, I get continuous hissing from somewhere, I get no power loss or anything, just really weird idle RPM's and hissing when my foot is not on the gas basically. It is strange. I think It is some sort of Vacuum leak but I am not sure.
To get a better picture of the 'hissing' noise, it is the same hissing as you would hear when letting the air out of a tire. That is the best way I could describe it.

View 1 RepliesHyundai - Sonata :: 2006 - Headlights Flicker On And Off And RPMs Shoot Up
I have a 2006 Hyundai Sonata that in winter does very strange things, almost ghostly. While driving, headlights flicker on and off, the dash abs and esc warning lights go on, and rpm's shoot up and stay there as if it downshifted by itself. I have to pull off the road and turn the car off.
Further, three different times I shut the car off and then nothing would work, including not being able to start the car. After it sits a while it then seems to reprogram itself and works properly.
I contacted Hyundai, and they only said bring it in and pay to diagnose it. But there appears to be no fix, as many have reported electrical problems for this model on the internet.

View 1 RepliesSonata NF (2006-10) :: Accelerator Pedal Pushed - No Response / RPMs Not Increasing At All
Just got into my 2006 Sonata V6 this morning. 120,000 miles. Drove last night, no problems. Started her up now this morning, noted check engine light and ESC lights on.
Pushed accelator pedal, no increase in RPMS at all. Put the car in gear (auto), car moves forward and backward, but pressing the pedal doesn't increase the rpms at all, so right now its not driveable. Luckily, its in the driveway so I know it could be worse. Took floor mat out, no interference issue there.
I changed the starter solenoid and that was over 45,000 miles ago. Never had that problem.
Sonata NF (2006-10) :: 2009 - Fast Startup Idle / Goes Up To 2200 RPMs

Sonata NF (2006-10) :: 2007 - Idling High / RPMs Shoot Up To About 1400
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.
Sonata NF (2006-10) :: Rough Idle / Lack Of Power Under 2000 RPMs
I have a 06 sonata 3.3L v6. I have been having misfire problems and lack of power under 2000 rpms and at idle when I am either a stop or just warming the car. What is happening I feel it shake and feel the misfire but after it gets up after 2000 rpm at highway speeds its completely fine. It struggles getting up to speed if i press on the accelerator. I have changed the spark plugs and all the ignition coils maybe about 2 months ago, I have also have changed the camshaft position sensor for the rear bank. I believe that it could be the crankshaft position sensor but I want to make sure....

Sonata NF (2006-10) :: Idling And Power Loss - RPMs Will Drop Below 500 And Then Spike Back Up
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 .....
