when you are going down the road and your coasting and pull it out of gear and let out on the clutch it dies and then if you put it back in gear and dump the clutch it will fire back up but if its in neutral and you let out on the clutch it dies what could that possible be .
My car has 66 miles.
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
Hello,
If your car is stalling when in neutral, then the first thing I would check is the idle air control valve (ICV). The idle air control valve is the component responsible for maintaining engine idle speed when in neutral. If the idle air control valve checks out, I would then look at the throttle position sensor, as it also affects idle speed. If any of those parts are faulty and need replacement, YourMechanic offers a repair and diagnosis service preformed by a certified mechanic that will commute to your location to replace the idle air control valve or throttle position sensor.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Common signs include lacking power when accelerating, rough or slow idle, stalling, inability to shift up, and the Check Engine Light coming on.
A malfunctioning TPS will cause your engine to run poorly. Generally the engine will idle fine but will have difficulty accelerating. This is because the computer isn`t telling the engine to inject as much fuel as is required, while at the same time airflow is increasing.
Some of the most common sensors that lead to engine stalling include the mass airflow sensor (MAF), engine coolant temperature sensor (ECT) and manifold absolute pressure sesnsor (MAP). The idle air control valve (IAC) and exhaust gas recirculation valve (EGR) are also well known for causing engine stalling.
When the throttle body gets dirty, it has a direct effect on how smoothly the engine operates. Signs indicating a problem include rough idling, jumpy or sluggish acceleration, poor fuel economy, and stalling.
Within a motorsport engine – or the engine of any vehicle, there is a throttle valve. The throttle valve opens when the accelerator pedal is compressed. A throttle position sensor is used to measure how open the throttle valve is and therefore controls the amount of air which can flow into the engines intake manifold.
This causes your throttle position sensor to adjust the engine intake manifold accordingly. This little sensor is essential to a correct mixture of air and fuel. It`s integrated with your engine control module and helps keep your idling and acceleration smooth.
Cleaning fuel injectors is generally not a do-it-yourself project, but you can clean the throttle body on your vehicle with common tools and specialized spray cleaners. While throttle-body cleaning is good preventative car maintenance, it should also help engine drivability.
The most common sensor which can lead to your car stalling is the manifold absolute pressure sensor (MAP) or the mass air flow sensor (MAF).
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit.
If your powertrain control computer is misreading idle speeds, this can cause a high idling malfunction. When your car`s throttle is malfunctioning, this can cause your car to stall or idle high. Often this is a result of dirt buildup in the air intake. Other times it can be a problem with a cracked intake tube.
Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.
When a throttle body is not functioning correctly, you`ll usually notice a distinctly poor or very low idle. If the problem is really severe, you might even begin stalling when coming to a stop or when the throttle is quickly pressed.
One is a vacuum leak due to a failed intake manifold or throttle body gasket. This will cause a major vacuum leak and trigger a lean condition.
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. First, be sure you have correctly wired, and assigned the throttle sensor signal input to “TPS Raw” in the Analog Settings.
During movement of a vehicle, the signal delivered to the TPS is in the range of 3.5–4.7 volts; a value range that indicates that the throttle valve is in the open position.
When the TPS goes bad, the throttle body may not open and the engine will not be able to run without air. It may cause erratic idling, stalling, and sudden surges of acceleration. The car may not start when the TPS is faulty.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit. Your engine needs air to run properly as well.
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.
When the idle air control valve fails, it inhibits the flow of air through the engine. When the car can`t receive air, it leads to engine stalling. The severity of this symptom can range from occasional stalling at first, to stalling immediately after ignition.

My manual car won’t go into gear, it turns on and the clutch goes down perfectly fine. It happened after my gears grinded, the car
ANSWER : If the clutch mechanism is releasing properly, and the shift linkage is not malfunctioning, your transmission will have to be removed from the vehicle and inspected. Once a transmission has been removed from a vehicle, if the problem is a broken or worn part or parts, and the transmission has 100,000 miles or more, the most cost effective approach is to just simply rebuild the whole transmission. There are transmission rebuild kits that are sold just for this purpose. Rebuilding a transmission is no big deal and is indeed easier in many respects than rebuilding an engine. You can rebuild your transmission right in your own garage. You can NOT rebuild an engine in your own garage due to the highly specialized, and extremely costly, machine shop equipment required. Occasionally, mobile mechanics will take on a transmission rebuild job especially as once the mechanic removes the transmission from the vehicle, it is just simply a modular unit that can be easily transported to a mechanic’s shop and rebuilt right there and then returned to your vehicle. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
My truck won’t allow me to change gears even when pressing the clutch. No gears go in at all. Makes it impossible to drive.
ANSWER : Hello, this concern is possibly the slave or clutch master cylinder failure. These two components use brake fluid to apply pressure for movement of the clutch system. This fluid breaks down in time and causes the seals to fail (leak). A low fluid level would cause this concern as well as internal leakage. Replacement of components would be necessary. This type of concern would need to be inspected. If you’d like, a certified technician from YourMechanic can come to your location to diagnose your vehicle, and possibly replace your clutch master cylinder if need be.
Car won’t go into gear. 2002 Audi A4 Quattro
ANSWER : Hi there – Your symptoms describe the behavior to expect when your clutch hydraulics go out (clutch master and clutch slave cylinders). Check your clutch fluid level – it may be low. If the fluid level is low, this usually means your clutch slave cylinder has worn out, not unusual with your mileage, and should be replaced. I recommend a malfunctioning clutch inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
I have a 1992 Chevy Silverado 1500 that won’t go into gear but the clutch pedal is hard and it still want go into gear when runnin
ANSWER : You should first pump the clutch several times and then hold it down and release air from slave cylinder. Retry the clutch to see if clutch releases. If not then turn off vehicle and put transmission in gear and hold down clutch and make sure your direction in front or behind you is clear and crank motor to see if clutch is free to turn. If still not free then you have ha defective pressure plate and need to replace it. Before that look inside transmission inspection hole and have someone push clutch and see how far the release bearing is moving to release clutch pressure plate. If it does not move much then you have a bad clutch master cylinder or linkage. If it move more than an inch then you have a bad pressure plate a long as release bearing is pressing it in.
Sifter floats from gear to gear and when letting out the clutch there is no response.
ANSWER : Hi there. Either the clutch has failed causing the transmission not to engage in any gear, or the transmission shifter plastic rings broke and will not engage the shifter. Check the clutch and make sure that it is moving when the pedal is pressed down. If the fork on the bell housing is moving and the wheels can be moved when the clutch pedal is depressed and then the wheels not moving when the pedal is let up, then the clutch should be in an okay shape. Most likely the plastic rings on the shifter housing has broke and making the shifter move around. If you need further assistance with the shifter moving around too much, then seek out a professional, such as one from YourMechanic, to help you.
Vehicle won’t go into gear when running, when turned off, vehicle will go into gear but won’t start. 1998 Ford Explorer
ANSWER : Hello – your clutch hydraulics are the problem here. Check the clutch hydraulics fluid level – and it may share the same reservoir as the brake master cylinder (both use brake fluid as the hydraulic medium). If fluid needs to be added, that means that probably the clutch slave cylinder is leaking – this might be visible as a clear, but bitter-smelling liquid on the ground under the engine. I recommend a clutch hydraulics inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
My truck died while driving. Now will start, but dies when I push brake. If I start in neutral, I can put in drive and go but dies – 2003 Ford F250
ANSWER : Hello – your symptoms suggest that once your cold start features are no longer needed – engine warming up – there is an air "leak" that ruins low speed running. Causes could be a leaking exhaust gas recirculation (EGR) valve, or leak in the air intake. A failing fuel pump relay (burned contacts) could cause similar behavior, contacts become hot, then won’t pass enough current to run the pump. Failing pump can also act this way – gets hot and fails. I recommend a starts, then dies inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
