Engine Almost Stalls Braking

Common reasons include an empty gas tank a faulty fuel pump a bad ignition coil fouled spark plugs water in the fuel or a failing sensor. I did notice however when the car stalls that numerous lights come on the dash.

Engine Stall When Braking Hard

If not the clutch plate is inspected for clearance of friction at 055 to 085 inch.

Engine almost stalls braking. Cvt recall completed and car ran better for about a year then started having the same problem. Engine stallshesitates sometimes car will shut off when pressing brake. Do what Steve said and pull the vacuum line to the booster and cap it off and see if it still stalls.

On mine due to the fact it only occurs when brake is on I suspect its an issue with the servo servo pipe or non return valve - i havent really investigated this yet but will be. So we did a few tests to find out what was going wrong. The stalling of an engine happens for a few different reasons but its important to clarify what engine stalling is.

It does not include when an engine feels like its going to shut off but doesnt - thats called an engine stumble usually due to an engine misfire. Lower it till you have. If the engine runs poorly you should address that symptom first.

Hi TheSubaruGuruBoston My 2011 Subaru Outback experiences full engine stall when braking hard to a complete stop from acceleration. When the car stalls I am able to put it back into park and start the car normally and drive away. The result is a rough idle and if you pump the brakes you can stall the bus.

This is all done by the idle air control valve. 1under normal driving conditions 2the engine stalls approaching a stop when the clutch is depressed it almost stalls every time I drive it whenever approaching a stop. If there is a problem with an engine control unit or the timing belt is off a tooth the engine may no longer stall simply because it isnt under a load when in neutral.

If it doesnt stall then its time for a new booster. The rpms go so low like its going to stall. My car idles at a complete stop in first gear.

It doesnt rev it just idles like its going to stall but doesnt. A vacuum leak anywhere in the engines intake manifold system will cause rough running and stalling and will be most problematic as the engine returns to idle. If the engine stalls during braking an inspection is necessary to narrow down the problem in order to repair the vehicle and avoid further issues.

The engine runs normally otherwise. I know this isnt an answer to posters problemBut almost exactly like hers. You have a vacuum line running from the back to the front for the power assist brakes.

It has only stalled once in the two weeks I have owned it. Ive seen a bad brake booster leak vacuum when the brakes were applied and almost killing the motor. I have a similar issue on my 108D but its not become bad enough yet to make it stall but it gets close- if I apply the brake it really makes the engine vibrate etc.

This isnt a real good test in my opinion. The 2000 Suburban we own is stalling out when under load or braking or turning for that matter. Just for a test try unhooking the power brake vacuum line and plugging it.

Your torque converter has a lock-up feature to improve gas mileageIf you stop very suddenly sometimes you can beat the computer and bring the car to a stop with the converter locked which will stall the engineNormally the converter unlocks as you brake to a stop allowing the engine to idle. Fort Morgan Colorado If your brake pedal is stiff and it stalls when you apply the brakes it sounds like the diaphram in you brake booster may be ruptured. If it was a high float level it would be the rear bowl.

If so the part is disassembled and the main housing is cleaned. If the engine stalls during braking an inspection is necessary to narrow down the problem in order to repair the vehicle and avoid further issues. It is an automatic transmission.

And then it shakes a little. You are correct that it disconnects the transmission. It doesnt always happen but enough to be concerned.

An engine stall is never fun. When the engine RPM drops below the normal range of 750-800 RPM for most cars this may indicate a dirty or faulty idle air control valve. This also has the result of taking all load off of the engine while stopped.

Stalling problems trace back to three primary causes. Automatic transmission cvt has trouble shifting gears- car jerks doesnt shift smoothly. Possible consequences could be a collision due to loss of power steering power brakes and distraction.

Check for a loose line in the engine compartment or a leak in the line. In cases where this valve is dirty or failing your vehicle will stall instead of slowing to an idle after the release of. If there is a leak in this line every time you push the brakes you draw vacuum from the engine.

Air in the brake fluid from a hole in the system can prevent proper pressure to the brakes. The engine stalls when coming to a stop or on deceleration. Its when the engine completely shuts off for no obvious reason.

A problem in the idle speed control system or transmission is the usual cause of this symptom. A lack of fuel not receiving enough air or insufficient power. Auto Repairs Are EXPENSIVE.

First the transmission is checked for contamination. The car may also stall due to a vacuum leak in the anti-lock brakes system.
