Car Stalling While Accelerating What are the Causes?

Several reasons cause a car stalling while accelerating but I have not known this not until it happens on me when my car stalls when I accelerate, I started diagnosing this problem and found out that the cause of car stalling while accelerating depend on the situation and the condition when the problem occurs.


When the car stall during cold rainy mornings
If the problems happened in this condition it means that the cause of stalling is moisture on a distributor cap because during the night when you park your car outside the garage especially when raining there is a formation of condensation inside the distributor cap. If moisture forms it will allow electrical current inside the distributor cap this current will lead to misfiring and will become severe to the point that the car will stall when the car is accelerating.

How will you avoid this problem?
If you anticipate that it is about to rain, park the car inside a covered parking and leave it there for overnight and there will be no formation of condensation inside the distributor cap.

When the car stalling gradually become frequent
If the problem happens gradually after the first time it was happen then the possibilities is that the car is suffering from a vacuum leak. The problem of vacuum leak usually starts out small then gradually become worst because of the pressure inside the engine. In determining how much is the fuel the car can get one of the key factors is the vacuum created in the fuel system.

Now, if there is vacuum leak on the fuel system it will it will affect the air/fuel mixture that enters the combustion chamber and will result to engine stalling. Bring the car to your dealer then ask the mechanic to check the engine for vacuum leak. Usually the EGR and the PCV valve is the most common source of vacuum leak.

When the car stalling suddenly happens at any given temperature
When the car happens suddenly the possible problem is the bad throttle position. Engine with fuel injected system have a part called throttle position sensor, the purpose of this device is to measure how far the driver pressed the gas pedal and thus the throttle. All data that is gathered will then feed to the engine computer which does the calculation, based on the calculation the resulting data will be used to determine how much gas the fuel injection system should inject to the engine combustion chamber.

Now, if the throttle position sensor provides a wrong data to the engine computer it will adversely affect the injection of the gas into the engine and this will result to engine stalling. Bring the car to a shop and ask the mechanic to check the throttle position sensor then repair if necessary this will fix the car stalling while accelerating.

WHat if, after the stall, the engine cannot be restarted for about 15 minutes. The engine cranks, but does not start. After waiting, the engine starts, the vehicle runs as if nothing had happened.

My 81 cutlass has a 5.0 Liter V8, when I have the car in neutral or park I can "gun" it with no problems, but in drive I have to press the accelerator more slowly or it will struggle and/or die...any ideas...?

In hot or cold weather, every morning or evening (when the car has been sitting at a place for some time) - car starts normally, but if put it in gear & accelerate without leaving it in idle for at least a minute or so after starting the engine, engine stalls. In fact even if I just put it in gear without leaving it in idle for sufficient time, I can see hear the engine weak and struggling. But if I leave it in idle for about a minute or so and then drive, no issues after that. It is a 2000 corolla with about 125k miles and has all 4 new iridium spark plugs since last year. And also ever since I had a missing gas tank cap last year, the check engine light keeps coming and going. Engine does consume some oil if I go at higher speeds. If I stick to around 50-55mph, no significant consumption.I keep experimenting with different thicker/synthetic oils but this problem seems independent of whatever oil type I use. Any inputs would be appreciated. Thx.

I have a 04 VW GTi 1.8T auto with the sport shifter - i'm having problems when trying to shift out of first gear (go over 10mph) because the car stalls out, revs up but doesn't jump into gear. I've noticed that I can prevent this from happening half the time by warming up the car for at least 40 minutes before attempting to drive. It's still rough at stop lights and jumps into gear, also around turns it slips out and jumps back into gear.

Hi, thanks for the visit. Regarding your problem, If the problem occurs frequently then it may be a case of a vacuum leak if this occurs not more often then the possibilities is that it has faulty accelerator pump, in either case bring the car to auto shop for checking, if you suspect a vacuum leak base on the diagnosis ask the mechanic to check the EGR and PCV valves however if the problem is the accelerator pump have it check including the entire carburetor.

hi i have a toytoa 2e we just replaced the engine and it ran amazing we went a fueled up and when we got to the end of the road it died. now it idles fine put when put foot down the revs come up and then it dies. if you keep pumping the gas pedal it will react but if your to hold the pedal down in any point it will die but will return to idle?????? any ideas be awsome

hi,

i have an 09 corolla and i've been experiencing weird accelerating and braking problems. My car has stopped letting me accelerate, while the rpm shot up and mph locked at like 20. If i turn it off and turn it back on it runs normal again but my engine light turns on. Sometimes when i'm driving the car sounds like it's pushing but nothing changes on the mph or rpm. It's like i'm accelerating but nothing is happening. My car has also shut off while the battery was still running by itself.

It said there was a pedal position sensor issue, i changed the wiring harness, but this is still happening. Any idea on why???

Have the Ignition control module checked. Having same problem with daughters car. Was getting progressively worse. Module was corroded and rusted and overheating. Replaced, problem gone.
