Car Stalling Problems

Why would a 2000 Dodge Stratus 2.4 L be sputtering and knocking and driving but hard at higher mph?

Well your question is not clear because of the gramatical errors, but I believe you are asking about knocking and sputtering at slow speeds but consistent and good at higher speeds....well here is my answer to you. The higher speed consistency compared to the lower sputter is probably one of two things or a combination of both or even a third. One, you have a rough idle which can be caused by: bad fuel injectors, bad ECU, or wrong or bad spark plugs. I would recommend that you disconnect your battery for 30 seconds to wipe the ECU and then try to start and drive the car again. If this does not work, then you will need to have a repair shop look at your fuel delivery (including fuel filter, injectors, and even your spark plgs). Your bad combustion can be any of the above and that would explain the sputtering at slow speeds. Now the second problem could be that your transmission is slipping gears and causing the vehicle to sputter and try to get in the correct gear until you get to a higher speed and a gear that is not malfunctioning. The third possible problem is that you Cam Gears are not properly functioning. If you have the 2.4 you have a dual overhead and the 2.7 or 3.0 is SOHC (if i am not mistaken). A DOHC means that you have one Cam opening and shutting for the intake of air while the other opens and shuts for the exhaust. One Cam can be malfunctioning and that is effecting the other which would cause rough idle and sputtering as well. That is all I have for you and any questions can be directed to tony_velociti@yahoo.com Thanks.

AnswerI had a same problem, mine was electrical. You should get a computer test done if your check engine light is on BEFORE YOU DISCONNECT YOUR BATTERY. Otherwise the computer wont test until so many miles driven. my test was Cylinder #2 misfire so i put on new wires and plugs, that did not fix it. I did a test with the brand new spark wires. I pulled the wire on the #2 cylinder (the other end of the spark wire was still on the COIL) and stuck a long peice of copper speaker wire in it. Then I took the other end of speaker wire to the frame and there was hardly no spark at all. The same test on another cylinder however produced plenty of spark. This proved to me that the problem was in the spark and it was not the wire or the plugs because i just changed them ($30.00) It had to be the COIL PACK, so I got one from autozone ($75.00) put it on and fixed the car. CAUTION: The test is dangerous you should us some kind of rubber insulator when handling the live wire and you also want someone else to turn the car over and off.

Cirrus clouds are formed at a higher altitude then stratus clouds. Cirrus clouds are formed at about 8,000 m. Stratus clouds are formed under 2,000m. Fog is actually a stratus cloud that forms near the ground.

The knocking problem you are having is most likely the gas you are using. If you switch to a higher octane fuel it should solve the problem.

Try a higher octane fuel

there are a few reasons for engines knocking......... - bad type of fuel - higher gear ratio at slower speeds if your engine knocks when you start it up then you have probably got a bad or dirty fuel in your car... change the filters or just get away with using it and change your petrol station if the engine knocking happens during driving then its because you are putting more gas on at lower speeds and higher gear ratios...you just need to lower your gear. say change from gear 3 to gear 2 and try increasing the gas gradually and slowly and the knocking should go away....

You can watch this animation to understand the principles of sputtering and especially magnetron sputtering. The main difference between magnetron sputtering and other sputtering methods is the application of magnetic filed around the target in order to energize argon atoms for bombarding the target. Using magnetic field leads to trapping electrons in the magnetic filed created around the target which enhances plasma. This results in higher ionization of Argon atoms and bombarding rate that finally increases deposition rate. http://www.heraeus-targets.com/en/technology/_sputteringbasics/sputtering.aspx

Lead was added to gasoline to inexpensively increase octane ratings and to also help reduce engine knocking.Increasing octane and reduce engine knocking are exactly the same thing, as the test method to measure octane of a fuel is to see when a standard engine begins knocking. The higher compression ratio the standard test engine can be operated at without knocking, the higher the octane of the fuel being tested.

Change to a higher viscosity oil and see if you can get the knocking to be a little quieter, you might get quite a few miles if you don't over-rev it and drive real easy.

Stratus or "blanket" clouds are usually low, featureless clouds that obscure all or part of the sun and sky. Higher altitude types are "altostratus" and "cirrostratus", which are formed from ice crystals.

A higher octane gas or an after market octane booster. But, if your car/truck is knocking, then something is wrong, either your timing is too far advanced or something more in depth..

Either get higher octane fuel, or retard the timing. That is about the only thing that will help

Elephants are vegetarians ! They don't kill prey (unless you count knocking over trees to get at the higher branches !)

In all states, 0.08% or higher. In some states, .05% or higher.

they are the same thing. "knocking" in an engine is the fuel igniting from the heat of compression of the fuel and the air together. in a desel engine this is how it is suposed to work because it has no spark plugs so the only way to ingite the fuel is by compressing the fuel and the air by a ratio of about 22 to 1. in a gas engine the fuel is ignitied by a spark plug, if you use low grade fuel the explosion can happen too early (before the spark plug ignites it) and cause a knocking noise in the engine whitch can cause dammage long tearm the typical compression ratio for a gas engine is 10 to 1. the more compression you have the higher grade fuel you need to prevent "knocking" whitch is why higher end cars need higher grade fuel because they have higher compression engines whitch make more horsepower with omperable size engines.

No. Responsibility is the key, and safe driving. Not restricting someone who is capable of driving from A to B without any problems.

Knocking is caused by preignition, where the heat in the cylinder causes the gas to ignite before the spark plug does. Try using a higher octane/grade gas and see if the noise goes away.

Trouble code P0507 means:Idle control system RPM higher than expected

Try buying a higher grade of fuel first. Some vehicles require more octane to stop them from knocking. You might also consider putting in some injector cleaner with the first upgrade of fuel to see if that helps and cleans out the injectors.

Stratus clouds are among the lowest in the atmosphere. Sometimes they turn into fog on the ground when they get low enough and are formed in air with high moisture, which is why you see them on muggy days. They are low-lying, uniform, horizontally flat, and are usually white or gray. Stratus in Latin refers to a blanket, which is what these look like in the sky. Altostratus and cirrostratus are two formations of stratus that form higher up in the atmosphere, and nimbostratus are mostly associated with approaching storms and rain.

Most likely is knocking. Try next higher octane grade of gasoline.

Yes. Alto clouds form the medium altitude group, but stratus clouds are at low altitudes.

The thing that could cause a knocking noise in your car is the same thing that could cause it in all cars A rod that or a flat lifter. it all really depends on where the knock is if its higher and to the back of the motor, it could be a motor mount

No. If your car runs well on a lower octane gasoline (i.e. no engine pinging or knocking), then putting a higher octane gas in your tank is just wasting money...
