To me it sounds like the mas wheel needs changing. acts like a clutch they do wear out and cause this fault. if it is the manual gear box type it can be the clutch spring weak in the clutch and this would need to be changed. some time its just come out of in liniment and will come back over time but you should have it checked. you need to take the inspection cover off and shine a light in side and have a look.

SOURCE: rough idle

Have you had the throttle valve cleaned?

Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: Vibration when in gear, and stalling.

The problem is the torque converter solenoid. I had it happen on my 94 Cavalier a few years back and was a cheap fix at the local car mechanic. What happens is the transmission warms up and hits a certain speed where the solenoid engages, but then it sticks and won't disengage until it cools down sufficiently. When it sticks, it causes the car to shake when slowing down and will snub out the engine if you come to a stop.

SOURCE: 96 mercedes c220, rough idle was every once in a

hi this sounds like it might be the MAF sensor may be on its way out, just looking through my technical data the only thing that would make it run this bad would be the MAF, what you will have to do is disconnect the sensor and then see if it idles better, if so then you will need to get this changed out for new one...hope this helps

I have a 2007 2.0L Honda Accord. I notice that there is alot of vibration when the car is idling; even when i put it in Park or Neutral. I would be grateful for any suggestions for dealing with this


Try cleaning the throttle body with carburetor cleaner. It could have carbon buildup causing it to run rough. I hope this helps and a can of carb cleaner only cost less than $5.00.

04 acura ti 3.2 litre engine vibration from idle to 1500 rpm


Wow thats a bunch of miles for only 9 yrs.
I would want to know if it is something related to the engine or transmission, or the wheels and suspension.
Does it happen in all gears, and at any road speed ? Can you rev up the engine and make the vibration, or does the car have to be moving ?

1996 mercedes c280 dies when put in drive


Engine stalls or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Idle drops way down in drive gear in park it's fine or running the A/C


what car is this, could be normal or not depending, like my 73 nova dogs down when put in gear but its suppose to with a 3 speed turbo. if its a newer car its not. and would sudject checking transmission fluid/filter or even replace both. if your fuild is low or old the transmission wont slip as easy and will make you car work harder to idel while sitting still.

I have a 1996 mercury mystique with a 2 liter and the car idles high and when i put it in gear it idles low and dies...i have changed the throttle positioning sensor, idle air control valve, mass air flow...


Wow you change everything, TPS was right thing to do and so is the Idle air control,and MAF and EGR, fuel pressure, So it idles high then some one tried to defeat the stall in gear? Even if there is a vacuum leak creating high idle it shouldnt stall in gear, , What color is the transmission fluid? when in gear in drive step on the acelerator pedal to maintain idle to prevent car from stalling. Just enough to maintain let say 1100RPM. Is there a vibration? I mean a torque convertor vibration. Torque convertor stall are common an GM and Nissan,very rare do I ever see it on Ford. I really belive the IAC is not getting power and is just been adjusted manually, cause I know its not the transmission, At idle in gear pull the plug on the idle Air control does it change in idle setting? If it doesnt change in Idle setting the adjustment that was use to control the setting lower the idle to its normal setting. Plug the idle air control in then.The idle air should change the setting. If it doesnt its not getting the signal it should.

2006 mercedes benz CLS500 rough idling


There are several reasons why the vehicle could be rough idling. If no check engine light is on and the vehicle feels like it's idling rough when you put it into gear. The transmission mount may be worn out which cause the vehicle to feel like it has a rough idle. Definitely at minimum you will feel the vibration when sitting in the vehicle.

Car was low,low on fuel,put half tank in car.drove about 3miles onto 4lane and kicked it. when car tacked out in passing gear it started heasitating.eased off the accelerator and shifted fine.kicked it...


Replace the fuel filter. That should fix the problem. You can follow the fuel line back to the fuel tank to find it. It is usually in the middle of the vehicle near the edge of the vehicle, like right under the passengers or drivers door.

Engine shut down


How is your engine at idle? It should be not less than 700 RPM. 1-If it is not then you can raise it up. 2-If your idle is OK then need to have transmission checked for torque converter lockup problem.
