Why does my car stall when I put the accelerator down?
When an idle control valve becomes contaminated or stuck, it may lead to an unsteady and rough idle. The car will stall if the valve is too clogged or when it finally fails. If, while holding the accelerator pedal down, a small amount of pressure keeps the car running at a stop, the idle control valve may require attention.
Why does my car idle when the AC is on?

Where does the accelerator cable go in a car?

What makes a car stall with a vacuum leak?
Misfiring or hesitation during acceleration is another common issue with vacuum leaks. As the leak gets worse, the car will begin to stall. A hissing sound and an illuminated “Check Engine” light will typically also be observed.
When an idle control valve becomes contaminated or stuck, it may lead to an unsteady and rough idle. The car will stall if the valve is too clogged or when it finally fails. If, while holding the accelerator pedal down, a small amount of pressure keeps the car running at a stop, the idle control valve may require attention.
Why does the engine stall when I put the car in reverse?
If the engine stalls, it may be caused by a faulty idle control valve, bad O2 sensors, or clogged fuel injectors. In regards to the “pan”, we’re not sure what you are referring, so it may be a good idea to contact one of our local professional mechanics to complete a battery inspection to determine what’s going on with your 2010 Ford Focus.

What should I do if my car stalls and wont start?
If your vehicle stalls and won’t start again, but then starts without issue after sitting for a few minutes, it may be a clogged fuel filter. Fuel filters usually need to be replaced every 40,000 miles or so, but because the filter is the easiest and least expensive problem to address, it’s often a good place to start.
Why does my car shut off when stepping on the gas pedal?

Why does my Jeep Cherokee stall while driving?
A significant number of drivers have reported that not only did their Jeep Cherokees lose engine power while driving, but in nearly all cases, stalling occurred without any warning and with no indicator lights on the instrument panel.
How does a CFI demonstrate an accelerated stall?
To demonstrate an accelerated stall, the CFI applicant rolls the aircraft into a banked turn and, while keeping the aircraft coordinated, firmly applies back pressure. The aircraft suddenly stalls, pitches down, and the applicant recovers.
When did a car crash due to accelerated stall?
Accelerated stalls can quickly turn deadly if they happen unintentionally, and abrupt maneuvers at low speeds can provide the perfect setting. On February 29th, 2012, while maneuvering to avoid traffic on final, a Cirrus SR22 crashed due to an accelerated stall.
What causes an aircraft to go into an accelerated stall?
Instead of calmly arresting the aircraft’s descent, the pilot banked, pitched up, and applied power abruptly. The bank and pitch most likely caused an accelerated stall, and the added power threw the aircraft out of coordination – causing the aircraft to roll inverted due to an incipient spin.

Why is my Dodge engine stalling and stalling?
In most cases, a bad throttle position sensor (TPS) fails to signal the engine computer about throttle operation. Other causes may be bad or worn out components in the ignition secondary system, causing the engine to accelerate poorly and even stall.
What causes a Ford F150 engine to stall?
If your Ford F150’s engine timing is off, it’s going to stall out, misfire, and altogether not run properly. Here are some of the more common causes of an engine timing problem: VVT Problem – Many modern engines are equipped with Variable Valve Timing.
Can a stalling engine be intermittent driveability?
Intermittent driveability problems of any kind are always a challenge to diagnose. When a customer brings you a vehicle and complains of a stalling problem, you may not have much to go on other than their description of what’s happening and when it happens.
What kind of car has no response when the accelerator is pressed?
No response when accelerator is pressed. Car is 1988 Audi Quattro w/>350,000 miles on orig. engine; has always had synthetic oil and runs great when running. This is only problem and we hope it’s not terminal. Seeking list of possible solutions. Problem has been “fixed” a couple of times, but recurs.
What causes a car to stall on a cold start?
It also manages the idle under changing engine loads, like when you kick on the air conditioning, turn on the headlights, or turn up the radio. When the idle air control valve malfunctions, you may experience a rough idle or the vehicle may stall entirely. This is especially true on cold starts.

If the ISC valve is gummed up with fuel varnish or dirt, it may stick, preventing the engine from maintaining the proper idle speed when the throttle closes. A faulty idle speed control circuit may also allow the engine to stall when idling if it fails to compensate for idle loads placed on the engine by the charging system or A/C compressor.
Why is idle speed not coming back up?
If the ISC system is working correctly, the PCM should adjust idle speed to keep the engine from lugging down when the A/C compressor engages. If idle speed drops down and does not come back up, the ISC system is not responding the way it should.
