Many rough idle problems are the result of burned valves. At a higher speed, the engine may not seem to be running rough, but may still be misfiring. On the other hand, if a valve is only slightly burned the cylinder may actually fire. It can also be a bad sparkplug, wire or distributor cap. In any case, you'll need to find out which cylinder is misfiring. If you've encountered a misfire problem that seems difficult to track down, run a compression test and see if all cylinders are ok. If the compression is up, track down other possible problems.
No, on a fuel injected engine it can cause high idle speed.
I blown head gasket can cause an engine miss which one cause a rough idle.
It can cause a rough idle. And it will also cause the engine to die when coming to a stop at times.
A faulty gas cap could cause the check engine light to come on but it would not cause a rough idle or engine noises. Start with having your local auto parts store read the codes. The codes will help determine why the check engine light is on.
A bad fuel cap can make your check engine light go on. It shouldn't cause your car to run rough or die.
incomplete combustion of fuel
It absolutly can. if the tank was not filled up prior to to sitting condensation will form causing water to mix with fuel. even a small amount of moisture can cause the engine to run rough.
It will cause the engine to run rough and eventually it will damage the valve and rocker.
Yes, and the check engine light should illuminate.
There are a number of things that can cause an engine to run rough. Plugs may be bad. Plug wires may be bad. If you have sensors, there may be a bad sensor. You could have water in your gas. Could have a burnt valve. There is a number of different things.
Power brakes use engine vacuum to get their power. If the engine is out of tune, the loss of vacuum will cause it to run rough. Try changing the spark plugs.
There are many things that can cause a rough idle on this car. The computer could be going out, the engine may not have enough oil, and the engine may not be getting enough fuel or electricity.
Have vehicle scanned to determine the problem
if you have a carborator, it may have to be adjusted
Check the engines timing to start with. Then check the engine for proper cylinder compression. Check the ignition coil and plug wires for breaks or leaking voltage.
If the check engine light has not come on, it is most likely a vaccume leak.
A bad crankshaft position sensor on your Chrysler 300 will cause the engine to run very rough or not run at all. The malfunctioning sensor can cause damage to your engine, if not repaired.
Your air conditioning unit is going out, Which is connected to the serpentine belt which is connected to the pulleys on your engine which could cause your car to run rough. Also you need to either have your air coditioning unit removed or replaced because it could do serious damage to your engine.
yes it is possible
Yes it could but, it should also illuminate the check engine light.
A vacuum leak, a bad injector and if the check engine light is on, check the codes.
Pressure test the convertor.
It's extremely unlikely. Much more likely is rough running (usually due to engine management fault) causing a lack of oil pressure. Also, keep in mind that an excessively worn engine can cause both low or erratic oil pressure and rough running, but this will usually be accompanied by a knocking noise.
Check the Cats have not disintegrated.
Rough idling and sometimes kills the motor. It could also trip the check engine light to come on.
