'99 dodge neon BAD gas mileage???
They didn't use DOHC engines after 98 in the Neons (US). You may need some oxygen sensors, they do not last forever. Most of the time they are neglected until something goes wrong with them. They are maintenance items, I just can't remember when they are recommended to be replaced (around 80-100K miles usually). If you have done the regular maintenance and are still wondering why your milage is not as good as it was before. Consider the following. Clean out the throttle body. Some carb cleaner and a rag - wouldn't hurt. You could have a bunch of carbon in there gumming things up! How many miles are on the car? Sounds like timing belt time. If your Neon is reaching the 100,000 mile mark, or has reached it without the timing belt being replaced, it is time to do it. I have worked on several Neons (own a 2000 w/116K Miles) and over time the stretching (wearing) of the timing belt does effect things like idle quality, fuel mileage, and sometimes responsiveness. While the timing belt is getting replaced I recommend replacing the water pump while you are in there. Another thing that may be hurting your mileage is the transmission, if it is an automatic. Have it serviced, (fluid and filter, NO FLUSH) and the bands adjusted. These too, over time wear and loosen up a little causing slippage. In most cases a band adjustment can tighten them right up. Tighter shifts mean less slippage, hence better mileage. Good luck with you Neon. I like mine, it has been a great car. I plan on keeping it even after purchasing a new vehicle!
What are some symptoms of too much transmission fluid?
Excess transmission fluid will cause foaming in any transmission. Foam does not flow like oil, reducing cooling and lubrication. It also implodes on compression between gears or in the hydraulics of automatic transmissions, causing severe damage (pitting).In an automatic transmission, you will have higher temperatures and poor shifting, as it depends on solid hydraulic pressure, not spongy foam to move the clutches and bands.Automatic transmissions with dip sticks should be measured with the engine running, and consider the operating temperature. Note here how the heat affects the measurement. It should not be filled to the top when cold, or checked not running.If it does not have a dipstick, it is measured with the plugs on the side, depending on specific instructions per brand of car.Manual transmissions normally don't have dipsticks (some do). They are checked from a plug on the side of the transmission, and the level should normally be at the level of the plug, not above.
2004 Dodge Neon SXT?
Car has 30k miles and up till now has had no problems. When fuel level gets near half engine trouble light comes on and there is a sporatic loss of power when accelerating. The idle becomes rough and sometimes the car stalls. If you remove the gas cap or fill up the problem goes away. Have regularly serviced vehicle and replaced the gas cap. Have run "cheap" fuel as well as Chevron, Shell etc. Any ideas. Thanks
1998 Dodge Dakota 3.9L v6, randomly misfiring on four cylinders?
a coil will cause this too happen when they heat up,what happens is they go to ground instead of sending the fire to the plugs,you might want to check that also,i been through this with my 99 dakota,and it drove me nuts trying to find it,one thing i did find out for sure is the don't like bosch plugs they run a lot better on champion plugs,if i was you id run a check on the coil when it was hot and cold and see what the reading is on the ohm meter,good luck.EDIT if the fuel filter is coming apart that can contribute to whats happening to it a great deal,you may wind up removing the tank on this one to see if that is the actual problem with it,
What would happen if somebody put a candy bar in my gas tank?
I've been repairing vehicle for the last 4 decades and my short answer is: "Almost nothing". The candy bar is basically sugar, flour, chocolate. Etc., depend on how it was made. Sugar DOES NOT dissolve in gasoline. Period! If the tank has some amount of water in it the may be that water and gasoline will dissolve with the water and may cause the vehicle has hard starting problem once the "Semi-solid, gooey substance" make it to the fuel rail or injectors or spark plugs. One note: The heat from the combustion cycle may burned off the sugar base substance and may clog up the injectors from inside out, thus make it inoperative (From spraying) and has to be replaced. So a lot of sugar (More than a candy bar) may do some damage, the fuel pump inlet may have a screen or "Sock" will be plugged up depend on the style of the pump. Depending on the set up of the fuel supply system like the injector, the diesel fuel injector, which may have the tip damage by the substance or water, the fuel injection pump, the fuel filer (Depend on how it was made) Etc. In summarizing, the sand, the water, the sugar, the salt or any liquid will have about the same effect more than a candy bar in the fuel tank. In short: Hard starting will be the end result and you may end up "Flushing" the system, cleaning the tank, replacing the injectors, some cases: The fuel pump has quit working, could be just "Coincident". Etc. I worked at several dealers before having my two repair shops and has been dealing with extended warranty or insurance. All of the companies inspector came out for the claim, he will verify that a "Substance" was in the fuel tank and most of the time that was enough after they review the history of the vehicle or the previous repair work orders, then approved the repair. Some tickets were good in dollars amount, some were not, just clean out the tank, replaced the fuel pump and go from there. Then if additional repair is needed like hard starting took place, the inspector will come out again. Hope I have answered the question. A little secret: All the years in the trade: The worst two will be water and paint remover just in case you want to get even with "Your Ex" ;o) HTH
How would I know if someone put water or sugar inside my car's gas tank?
My car broke down. It was running fine. I think someone I have a problem with put something in my gas tank. The mechanic told that the head gasket blew up and water and oil mixed up, but when i first opened the carburetor it was full of white looking stuff i guess it is a mixture of water and oil i think. the head gasket is fixed, but he is telling that he is still having a problem with the car and has to change the carbourator. How would I know if this person did something to my car?
Can higher octane fuel help to clean my engine?
Possibly. Here in the US, the government has set minimum standards for the amount of detergents gasoline must contain. Furthermore, some automakers have come up with standards of their own, which exceed federal government standards. Gasoline meeting these standards is Top Tier gasoline.However, it should be remembered that these are all MINIMUM standards. It is perfectly acceptable for refiners to exceed these if they wish. For instance, Top Tier gas could have just the minimum detergency required for Top Tier certification. Or, it could have (say) three times the minimum. And at least in theory, it could have different and/or additional additives that are above and beyond those required for Top Tier certification. It would not be unrealistic to suspect that, if refiners DO choose to add more and/or better detergents, they would do it in their more expensive grades (even if for no other reason than marketing) rather than the cheap stuff.There are a couple of problems here, though. It is generally not known to the public whether more expensive fuel grades do indeed have higher detergency, or how much if they do. Companies may promote such products as Chevron Supreme with Techron and Shell V-Power with Nitrogen, suggesting that these products have more of these detergents than regular and midgrade fuels. But whether they indeed do is unknown. Also, it is unknown whether a higher detergency and/or possibly additional additives is actually beneficial. It may be that it ISN’T beyond a certain point, and that any claims that it is are just marketing puffery. Unfortunately, there isn't much (if any) independent testing of the cleaning power of various gasolines on real engines to verify this.
What happens if I overfill my power steering fluid?
Most modern power steering system has a pressure relief built into it. Most are in the cap. The fluid will expand with heat and the pressure relief will let it over flow out of the system. Then you have a mess. That’s it. No harm done. To the system at least, but not good for the environment.
My boyfriend accidentally put kerosene in his car.. what should he do?
We were out of gas and his mom told him to get the gas that was on the porch, he smelled it and it smelled like unleaded fuel. We put it in and drove not even a quarter of a mile and it started to make this weird noise. I called my brother and he said that his car is pretty much ruined. Now his car wont start, but my friend trevor said that it will start he will just have to do so and so to it and then it will be running fine. Is anyone an expert on cars here? I need legitimate answers. By the way his car is a 2005 dodge neon. Thanks
