water in the fuel can cause an idling motor to sputter and/or die.
because itt needs to be work on
Could be in need of a tune up.
Could be EGR valve sticking open or dirty at an idling condition or hesitates when accelerating.
Possibly. The main thing it can cause is severe engine wear. Too much oil is just as bad as too little.
A malfunctioning battery can't provide enough power to your ignition system when the motor is idling can cause sputtering. If there is not enough gas, that can cause your vehicle to sputter. If the spark plugs fail to fire will also cause your vehicle to sputter.
If the check engine light comes on it is best to take it to a auto part store or mechanic for a diagnosis. They will be able to inform the owner what the issues is.
I have an 04 Venture that did the same thing. Turned out to be the Engine mounts, apparently it is really common. Since i have gotten them replaced i haven't heard the noise or had a single problem.
Replace the Idle Air Control Valve only about $50. This would cause funny idling and stalling out.
It could be many things. Try spraying brake cleaner on the back side of the engine where the intake manifold meets the cylinder head. If the gasket is bad the engine will mis fire or stumble.
A car that is stopped with the engine running.
Have it checked for codes, and diagnose the code.
Could be your timing belt.
CHECK THE TIMING
== Bad bearings?Loose wrist pin?Only happens under extreme engine load? == PredetonationRunning hot?Timing too far advanced?Fuel octane rating too low?
Sans other problems, my experience dictates that you have a fuel filter that needs changing. Idling? hardly any pressure through the gas lines. Accelerating? pressure builds and, the fuel filter being clogged somewhat, the gas can't get through, and it's choking, so to speak. Try changing the filter. Get a Chilton's mechanic repair book and look at the trouble-shooting chapter, and look for your problem.
an idling diesel engine or snoring :]
check the engine mounts
Yes, "sparkling plugs" is definitely detrimental to idling or smooth running of an engine
Not sure if this will help but try this answer on another site. http://answers.yahoo.com/question/index?qid=20060623092709AAKy5vf
It may be a EGR valve issue. This valve is normally closed at idle and opens at about 40mph.
Engine idling in park
The fan clutch is not functioning properly. Replace.
NO not that engine.
