Azera HG (2011-16) :: Rough Idle / Vibration When In Park Or Stopped At Lights
Rough idle whenever you are not in motion. It is very obvious, and a little frustrating as my previous 5 cars never had this issue. I love the car, but the vibration is driving me a little crazy. When the car is in park, and you lean on the outside of the car it is also vibrating heavily. I hate to have them start taking things apart when there is less then a 1000 miles on the clock.

I have a 2003 Hyundai Santa Fe. Within the last 2 months or so I have changed my timing belt, spark plugs, and all belts that needed to be changed. I notice that when I am idle at a traffic light, the car is a little rough or bumpy. Is this normal for its age, or should I be looking at something specific.

My 4 cylinder Tacoma vibrates a lot when it is idling, especially sitting in "drive" at traffic lights. My regular mechanic has tried various things to remedy it but none has really worked. He suggested the valves may need to be adjusted. Is this plausible? Or is he off-base? And is it really expensive?
View 4 RepliesLexus LS 2007+ :: Idle Hovers Around 450 - 500 RPMs And Pretty Rough
After the engine is warmed, my normal idle in drive, park, neutral, or reverse is around 650-700 RPMs.
I have recently noticed that when a combination of conditions occur, my idle hovers around 450-500 RPMs and is pretty rough. This low, rough idle occurs when:
1) The car is in drive;
2) The car is at a full stop (foot on the brake or auto-brake hold);
3) All accessories are off (heated seats are off, radio is off, headlights are off); and
4) HVAC is Off.
I went to the dealer and they ran diagnostics. No error codes were recorded. The dealer looked at other ls460s and said they all do that. By the way, I noticed this after my VSR was done.
Toyota - Corolla :: 1997 - Rough Idle / Stalling Noises While Stuck In Stop And Go Traffic
I have a 1997 Corolla with 150k miles.
I had my catalytic converter and flex pipe replaced this summer. Lately, my car has been idling rough. While stuck in some horrific stop and go traffic three weeks ago, it started to make noises as if it would stall out. It didn't, but it still sometimes makes those noises.
The car seems fine on the highway. No loss of power. I did think that the hood felt too warm on a recent trip, but the temperature gauge in the car showed no issue.
The car hesitated when I tried to start it last week, but normally starts fine. It was the first cold day of the year.
I saw some white smoke come out of the tailpipe last week. It only happened once. Coolant and oil levels are fine. The spark plugs look good.
The fill pipe has been leaking gas for several months. It leaks if the tank is more than half full and it drips a bit of gas when I fill up. Two mechanics have not been able to find the leak and have told me not to replace it until it is a problem, given the age of my car.
I took it to a mechanic today (not the one who replaced the cat). He told me that the rough idling is due to the new flex pipe being shorter than what was originally there. He assured me that the car is fine to drive long distances and that there was nothing wrong with it. There's no check engine light or anything on the dash to indicate a problem.
I should be relieved, but I'm not. I've lost confidence in my car. Can the stalling noises and rough idling be explained away by a changed exhaust system? Or are these signs of a problem about to happen?
Lexus ES 2007-12 :: Belt Area Chirping At Idle / Steering Wheel Vibration At Low Speed
2008 ES350 with 170k miles. My wife drives the car almost exclusively but we went on a road trip and I had the opportunity to drive it for a few hours.
I noticed at idle there is a chirping sounds from the belt area like it could be a water pump or another pulley going out.
Other data points:
At speeds over 80mph I feed a vibration in the steering wheel. we are 1k over getting the tires rotated so that may clear this issue up.
low speed in a parking lot I had the wheel at full lock turning and it felt like it "slipped" and it made a noise. This made me think the power steering pump could be what is going out.
I need to check the fluid levels tonight and see if either is leaking ( there is nothing on the garage floor)
Are there any good DIY's for a waterpump or power steering pump replacement? Once I diagnose the problem I would like to fix it myself.
Are these common issues with the ES350?
Toyota - Stall - Tacoma :: 1999 - Stalling During Idle At Traffic Lights?
Had a tune-up and a mechanic also looked at the accelerator pedalfor some reason, but no report regarding the fuel injection or regulatory components which I suppose should have signaled an issue when the computer diagnostic was run if I am to understand the mechanic's position.

View 15 RepliesMercedes-benz - C-class - Fuel-economy :: Idle Speed / Wasting A Lot Of Gas Sitting At Stop Lights And In Traffic
A few months ago I bought a used 2007 Mercedes C280. Overall, I've been very happy with the car. The first month or so was heavy on longer highway driving, and it seemed to be getting decent gas mileage. The last couple of months have been mostly short range city driving, and the mileage seems significantly less. I wonder about the idle speed, on the assumption that it may be wasting a lot of gas sitting at stop lights and in traffic. The tachometer reading isn't always consistent at idle, but fairly often it's up close to 9,000 rpm. What should I be seeing, and does this need attention?
View 6 RepliesLexus SC430 :: 2002 - Shaking Slightly When Idling At Traffic Lights
My high mileage 2002 SC430 seems to shake very slightly when I the car is idling at traffic lights (both when it is warm and when it is cold). The shaking is very very slight but it is noticeable. The shaking does not occur if the air conditioning is running or when the car is moving. The check engine light is not on.
The previous owner did mention that the alternator may need to be replaced eventually, but I don't know if this could be related.
Gmc - Safari :: Slight Rough Idle With Noticeable Dimming Of Dash Lights In Dark At Idle?
2000' GMC safari's electrical system. To begin, she has 95,000mi, an although that's about a year old, a duralast gold battery about the same age, and 13.8 volts at idle on the meter at the battery. The problem, over the past couple of weeks, I'll start it and drive off as normal, an the thing wants to stall for about two seconds. After that, no problem whatsoever. One time, it actually did stall on me, and everything went dead for a couple of minutes, no juice whatsoever; noticed that even the clock in the radio read 12:00. After a few minutes, I tried to turn the key again, and it started right up. This a.m., I went to start the van, and it initially would not turn over. The started motor turned but in a weak manor. At that point we went completely dead again, no electricity whatsoever.
The strangest thing is what happened next, I pulled the hood latch release as I was about to investigate and noticed the guages on the dash move when I did, power was back. The van then started but barely, and when it did it stumbled for a few seconds before driving off without so much as a hiccup the rest of the day. The only other possibly related symptom would be a slight rough idle combined with a just noticeable dimming of the dash lights in the dark at idle. Also, I should mention that I have checked the battery terminals and they are tight and clean, the van is in excellent shape mechanically, averaging 20mpg combined, smooth acceleration, no leaks, "using oil", white or black smoke, etc. Plugs, cap, rotor, and pcv are recent. Egr and maf are both clear.
Celica :: 1992 Toyota Rough Vibration At Idle
I just bought a 92 Toyota Celica for something to play around with. It's got just over 200,000 miles and everything seems to run alright except there is a really rough vibration at idle. The vibration is so bad that it's almost visible. You can still feel the vibration in drive but it isn't nearly as bad.
Any clue at what could be causing the vibration? I'll try to get a sound clip or video uploaded ....
Touareg :: Cold Morning Vibration / Rough Idle
Since my V6s very rough ride only occurred on cold mornings (fixed with a new driveshaft early this year), I wonder if some of the newer owners will be complaining of this problem soon, now that we're embarking on fall.
The symptom was strange. On cold mornings, between 30 and 50, the Touareg would feel as though it was riding on extremely rough pavement.... over 50 it was fine, and then, after about ten minutes of driving, it went away at all speeds.

View 1 RepliesCamry :: Rough Idle - Vibration Start As Soon As RPMs Drop A Little
I've made posts about a rough idle before now I noticed something new about it. I noticed when I approach a red light the vibrations don't start immediately. They start as soon as the RPMS would drop a little. They stay above 500 but it seems like it's below 750. As if the engine is slightly starved from power? Now i'm wondering if it could be related to another problem I have.
Whenever I start the car, the battery light flickers until the car is started all the way. This is on a 2007 Camry 4 cylinder. So far everything iv'e done is: New NGK Spark Plugs, NEW OEM mounts (all 4) Seafoamed the engine, Seafoamed the throttle body, cleaned the MAF sensor, New air filter, and cleaned the air filter box, replaced the PCV Vlave, new belt, new alternator (duralast), and a new battery (from autozone).
Ford F-150 - 1997-2003 :: Rough Idle / Engine Vibration
Bought the truck knowing it needed a little work because it sounded like a diesel when running. So I had the timing chain, tensioners, water pump, etc. replaced and that fixed that problem. Then, a couple days later, a spark plug blew out of the engine. So, I go to do a full tune-up to find out that 3 of the 8 cylinders already had heli-coils in them.
I pulled those three and bored out and re-tapped the cylinders using the Cal-Van inserts. This has worked beautifully so far. I also replaced all of the other plugs as well with double platinum plugs. I also replaced all COPs. This got the truck running again and it drives great. No loss of power whatsoever. It just runs like a dog at idle. As soon as I give it throttle it smooths out completely.
It seems like the problem gets worse as the engine starts to get up to normal operating temp. Basically, if I am idling, in gear or in park, the truck shakes pretty bad. It kind of feels like it's starved for fuel or barely missing. I do not have any codes though and if it is a miss, it is completely gone under throttle.
Other things I have replaced within the past couple of weeks:
EGR
EGR vacuum solenoid
DPFE
Both PCV elbows
PCV valve
Air filter
Harmonic balancer
Other things I have done:
Cleaned IAC
Cleaned throttle body butterfly (including EGR ports)
Checked TPS voltage
I'm sure there are other things that I am forgetting.
The idle seems low to me but I'm not sure what is considered standard for the 5.4l. Mine idles around 600 in park once engine is warm and the needle doesn't move despite the roughness felt. Just going by the tach, you would think that the idle was smooth as silk.
