My car makes a loud noise, shakes and has trouble starting when we put gas in it.
When we first got our car we noticed that when we put gas in it, it would have trouble starting, it would shake and sometimes we would have to try 2-3 times to get it to come on. It was never really a big problem but on Friday my mom took it to work and called me saying it was acting up and she didnt know what was wrong. She drove it home and explained that it drives almost normally but it is making a very loud noise, it sounds almost like something is stuck in a fan or the motor is going out- but we had it checked by a mechanic and he could not find out what was wrong, but confirmed that ther
Experienced mechanics share their insights in answering this question :
The purge valve is most likely leaking fumes into the intake manifold when your are refuelling the vehicle. This will flood the engine with gas fumes and cause the hard start and run rough until the excess fumes are burned off. Have the purge system checked to see if purge valve is leaking fumes when it is closed. If it is leaking then replace it. As far as the noise I would need more info on this since a mechanic already said they could not find any problems.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
This occurs from the purge valve not working properly. It can also be a vent valve issue, but that is not as common. These are part of the EVAP emissions system. If the purge valve is not closed when fueling, it can allow too much fuel vapor to enter the engine which will cause this to occur.
A loud squeaking or squealing noise while accelerating could mean there`s a problem with your engine belt. It could mean the belt`s loose or worn. Or it could mean that one of the belt`s pulleys is starting to fail. A loud rumbling noise when accelerating might suggest there`s a problem with your exhaust system.
If your exhaust pipe is loose, it can cause your car to make a helicopter-like sound. This is the problem with the mounts or brackets holding the exhaust pipe. You`ll need to have a mechanic take a look at this and tighten or replace the mounts.
A worn out or faulty spark plug is a leading cause why your car engine vibrates or shakes uncontrollably. A worn out spark plug can prevent the fuel-air mixture to not get properly ignited in the cylinders, thus leading to misfiring.
One common cause of shaking while idling can be loose engine mounts. Engine mounts are the connections between your engine and your car — they keep your motor safely attached while dampening vibrations produced by your engine. When those connections wear out, you`re more likely to feel the vibrations.
Poor Quality Fuel
A major reason of vibrations in a vehicle is poor quality of fuel. Poor quality fuel usually has low levels of octane, because of a lack in octane, the engine tends to experience more load.
Your car`s intake and exhaust valves can get stuck or wear out. This can lead to premature ignition inside the combustion chambers. It can also cause a rattling noise similar to the sound created by glass bottles clinking together when you accelerate.
When the seal is broken or damaged, the wheel bearing will fail and start making noise. Many describe this as an airplane noise, but others might say it is like driving over a rumble strip on the side of the highway or the whirring of a helicopter propeller.
The most common reason is bad motor mounts. They are designed to stabilize the car engine while driving. That`s why disconnected or defective motor mounts will make your car shaking at idle. A broken timing belt can also be the reason for engine shaking.
The most common reasons for your car to excessively vibrate are a problem with your tyres, wheels, brakes, steering, suspension, axle or engine.
Improperly functioning spark plugs cause an uneven burn of fuel in the engine, resulting in fluctuating RPMs and a louder noise. You might also experience increased vibrations of your vehicle while sitting idle or while traveling at low speeds. These vibrations originate from the engine and can shake the entire car.
What does a bad catalytic converter sound like? Often, a clogged catalytic converter sounds like a rattling noise is coming from under your vehicle and engine when you`re starting, idling or driving. Excess heat or damage in the converter can break apart the honeycomb materials, resulting in the rattling noise.
Rattling Noise – Once your catalytic converter becomes older or damaged from fuel mixtures, the honeycombs on the inside can begin to collapse and/or break apart which will cause a rattle to occur.
Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.

ANSWER : The purge valve is most likely leaking fumes into the intake manifold when your are refuelling the vehicle. This will flood the engine with gas fumes and cause the hard start and run rough until the excess fumes are burned off. Have the purge system checked to see if purge valve is leaking fumes when it is closed. If it is leaking then replace it. As far as the noise I would need more info on this since a mechanic already said they could not find any problems.
My car will be starting perfect and when the gas tank gets lower it will start having problems .
ANSWER : Based on the information you gave, it sounds like a possible fuel starvation issue, caused by a partially blocked, in-tank fuel filter or a crack in the fuel pump housing. The remedy would be to replace the fuel pump assembly and filter. The overheating may be caused by several things, including a stuck thermostat, faulty water pump, or even a cracked head gasket. I suggest having a certified technician, like one from YourMechanic, inspect the relevant systems to pinpoint the cause of your vehicle’s hard starting issue and overheating problem.
when i turn it make little noise. when press on brake and put on reverse it’s makes weird noise and shakes. thank you
ANSWER : It sounds like you may be dealing with a few issues. I would start by asking if there is a check engine light on? If there is, then getting the engine control module scanned for faults would be the first step to diagnosing the low power issue. As far as the noise over bumps and when turning, there could be a damaged CV joint or axle shaft, or there could be a loose suspension or steering component. Weak motor mounts could cause a weird noise and shake when going into reverse with your foot on the brake, so it’s possible those have failed as well. I would suggest having a qualified mechanic, such as one from YourMechanic, diagnose the noise over bumps and the noise when put in reverse.
My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
My car would not start. The ectricty is good. I put some chemical in the gas and the car start but the engine light still on.
ANSWER : Hi there. When you have an issue with start up that was "resolved" by adding a chemical in the fuel, that leads me to believe that either you have a fuel delivery problem (caused by a dirty fuel filter, clogged fuel injectors or throttle body) or an worn out ignition problem, caused by worn spark plugs. First and foremost, I would recommend AGAINST using a chemical additive to repair your vehicle (especially if it’s an ether product as this can cause a serious backfire and could create major engine damage). Instead, have one of our mobile mechanics come to your location and complete a car is hard to start inspection.
I have trouble starting the vehicle every time I put gas in the car
ANSWER : As you may know, this issue is commonly related to the evaporative emissions (EVAP) system which is comprised of a few components, one of which you have already addressed, the purge valve. In some cases, when you have an air leak in the EVAP system, then the manifold absolute pressure (MAP) sensor will not be able to determine the air density, and the mass airflow (MAF) sensor will not be able to correctly determine the volume of air entering the engine. This will lead to an over-fueling or under-fueling situation depending on the size of the air leak and the engine’s operating speeds and load. This could eventually lead to destroying the catalytic converter as well. I would recommend having an expert technician, such as one from YourMechanic, take a look at your car to diagnose your starting and stalling problems.
can a alternator belt make car not start because I was driving my car and I ran out of gas and i put a little gas in? belt broke
ANSWER : Hi there. It is very difficult to diagnose this type of hard to start issue remotely due to the fact that both issues; running the vehicle out of gas and the alternator belt being broken can cause the car to not start. It’s kind of like a chicken / egg type deal. In order for the fuel pump to deliver fuel, it needs power. It receives this power from the battery initially, but then the alternator. If the alternator belt is broken, you won’t have power supplied to components. It is best to have a professional mobile mechanic complete a car is hard to start inspection to determine what is causing the starting problems on your Dodge Neon.
My car makes a really annoying noise and sometimes dies right after
ANSWER : Hi there. From the description you have provided your vehicle’s moaning noise and intermittent stalling problem could be any number of things. It could be a failed alternator diode making the moaning noise and affecting the idle.
A failed alternator diode(s) allows voltage to flow both directions or no flow at all resulting in noise heard and erratic electrical operation. It could be a faulty idle air control valve. The idle air control valve can make noise and would account for the erratic idle and sporadic dying. It could be an accessory component, such as an A/C compressor, serpentine belt tensioner, or idler pulley, power steering pump making noise and placing undo load on the engine at idle. If you would like to have this done, a certified professional from YourMechanic can come to your car’s location to diagnose the noise and stalling issue.
