Why Does My Car Keep Stalling? 1 Reply. If your car stalls and you can’t seem to figure out why, driving can be a frustrating and frightening experience. In general, a car stalls when the engine stops turning and is not delivering air, fuel or spark at the proper time or volume.There are a variety of specific problems that cause a car to stall but fortunately, most can be fixed without an expensive and time-consuming trip to the mechanic.f the performance of your engine changes or your car stalls as you drive up and down hills, you could be experiencing fluctuations in fuel pressure caused by clogged fuel injectors or a dirty fuel filter.

- Could be a vaccum leak. The actuator on the a/c baffle in many cars is controlled by vaccum pressure, and a leak (or clog) could affect idling as well. Get a can of starter fluid and spray around the vaccum lines. If the engine revs, you've found the leak.

- Several things, from bad rotors to uneven tire wear, can cause your car to vibrate and leave you gripping the steering wheel to try to control it. If your car vibrates while you drive, it could indicate a problem from the engine to the tires. Find out the top reasons why your car vibrates.

- My Engine is Shaking, and the Car Hesitates. So your engine is idling poorly (shaking, misfiring), and you are not able to accelerate properly. There are a number of potential causes for this problem.

Stalling in Induction Motors, its effects and prevention Stalling of the motor refers to a condition, where the motor is unable to rotate. This condition can be caused either due to any obstruction in the load or due to any problem with the motor such as bearing seizure, etc. This condition is also known as locked rotor.

Greg's Engine & Machine This is due to cold and wet weather and the fact that the engine is cold. This moisture allows electrical current to arc inside the distributor cap and this arcing causes the engine to misfire. During acceleration this misfire gets so extreme it can cause the engine to stall.

Stall (engine) A car fitted with an automatic transmission could also have its engine stalled when the vehicle is travelling in the opposite direction to the selected gear. For example, if the selector is in the 'D' position and the car is moving backwards, (on a steep enough hill to overcome the torque from the torque converter) the engine will stall.

Stalling in Induction Motors, its effects and prevention The stator currents also increase. The equivalent of the motor stalled condition is that of a transformer whose secondary is short circuited. The high current drawn will cause damage to the windings and cause the rotor to heat up. Stall protection devices work by monitoring the motor current and the speed.

What exactly is a compressor stall? 2 Answers 2. A compressor stall occurs when there is a disruption or breakdown of airflow through a turbine engine. It can usually be identified by a loud bang, pop, or buzzing sound. Expect to feel a loss of thrust, see your RPM winding back, and your EGT/ITT/FTIT either increase or decrease based on your altitude.

Why Does My Car Idle at a High Rpm? If the carbureted vehicle continues to idle too high after warming up, it may have a defective power circuit or accelerator pump. Replacing the accelerator pump or carburetor usually brings the idle speed to normal. Ignition problems sometimes lead to a fast idle.

- If your car is slow to start, is hesitating or stalling or if the engine is flooding or eating too much gas, it may be time to get your hands dirty and rebuild your car's carburetor [source: AA1car ]. Follow the easy steps below to save a lot of money and get your car working again.

- The culprit behind some of these accidents is a failed camshaft position sensor (CMP sensor). Sometimes a CMP sensor can fail without warning, causing the engine to shut off. Other times, the driver may be unaware of developing symptoms until the engine refuses to start.

Solving Intermittent Stalling Problems Any of these conditions can upset the fuel calibration of the engine and cause a stalling problem. Intermittent stalling can also be caused by a bad idle air bypass motor or a idle speed control motor. If these devices fail to provide the correct idle speed, the engine may die. Sometimes the fault is in the PCM or the inputs to the PCM.

- In other words, stall speed is the engine RPM at which the torque converter transfers the power of the engine to the transmission. In the real world, the torque converter's stall speed roughly equates to the clutch engagement point on a manual transmission.Let's say you're driving your stick-shift car around town. Normally, you'd give the car a little gas and ease off the clutch pedal gently enough to get a smooth start.hat many people don't know is that the torque converter is a tunable device. Stall speed is determined by several factors, including the distance between the impeller and the turbine and the design of the stator.

- Single cylinder misfire, which can manifest while stopped yet clear up while driving. Random misfire, like above. Vacuum leak, again like above. Fuel delivery issues, like clogged fuel filter or weak fuel pump will sometimes cause an engine to chug and stall at low speeds. Base engine issues, like cam/crank timing can really cause erratic behavior at all engine speeds, but again may be more noticeable at a stop.

Car now hesitates or stalls when cold. What should I check? When it is cold, say 30-45 degrees. I turn the key and the car starts right up, it idles a little fast, from I suppose a choke of some kind. In 30 seconds or so the engine purrs. BUT, if I put the car in 1st gear and start to release the clutch the engine jerks and will stall if I don't rev the engine and take off slowly. It then takes about 3-5 minutes to warm up and run fine. Also, if I let the car idle for 5 or ten minutes before starting to drive, there is not hesitation.

Why does my car stall when I'm idling at a stop light? Your car stalls at stop light is caused by either fuel or air hesitations when the injectors air/fuel mixtures are out of proportion. You can also put a pint of Gas Treatment in your gas tank to see if it can do any help.

- Bucking and stalling can be a torque converter clutch problem. These two conditions can also be caused by many other things. This is why I wanted to discuss it a little further. This lock-up device is important because it helps provide maximum fuel economy for the vehicle when cruising.

- The hotter the engine gets, the more the fan has to spin. If the fan clutch is not functioning correctly, the fan won’t spin at the right speed and therefore can’t provide the cooling needed. It could spin too much and waste power coming from the engine, or spin too little and not cool the engine enough.

- SYMPTOM SUMMARY. The engine hesitates when accelerating. The vehicle may stumble or stall when the accelerator is pressed or may exhibit an immediate lack of power. USUAL CAUSE. This symptom may be caused by several items.

How can you fix a car that stalls while idling? Take it to a mechanic and find out why the idle is off. There can be multiple reasons. Electrical parts wearing out is common - bad plugs, bad ignition coils, bad battery, bad alternator, bad plugs, bad plug wires, etc. ad nauseum. Fuel system problems are also a common cause of this - bad fuel pump, clogged lines, clogged filter, bad gas (fresh gas and a gas treatment will fix that).
