Why does my car die when I back up?
Hi there. Usually when you shift into reverse and engage the brake it will cause the engine RPM to drop; as it’s creating a load against the transmission and the engine. If the engine stalls, it may be caused by a faulty idle control valve, bad O2 sensors, or clogged fuel injectors.
Why does my car stall at highway speeds?
The engine may start and idle fine, but run out of power or even stall at highway speeds. If the engine starts right back up after stalling, the likely cause is low fuel volume delivery because of a weak pump. If the engine is running normally one minute, but suddenly quits, loss of ignition may be the problem.
What should I do if my engine stalls?
It’s worth checking with a know working oil pressure gauge, so that you can get the real readings (i.e. 40 psi… If you are feeling vibrations in the drivetrain when only going 20 to 40 miles then the problem is inside the transmission. If you just had the transmission rebuilt then take it back to the rebuilder to diagnose the problem…
What causes an engine to stall at idle?
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.
What happens when your car loses all power?
Was about to call break down, then suddenly all power came back and I was able to start the car. Assumed it was some electrical glitch, didn’t think much of it. All fine been driving as usual all of last week until today – came back to car, unlocked fine, all power fine and then electrics go completely dead just as I’m turning key to start engine.

What are the symptoms of an engine stall?
Here are some of the most common symptoms of, a faulty mass airflow (MAF) sensor; The engine is very hard to start or turn over. Engine stalling shortly after starting. The engine hesitates or drags while under load or idle. Hesitation and jerking during acceleration.
When does a diesel engine start to lose power?
Then, after about 1/2 hour it starts losing power and in a period of about 3-4 minutes it loses so much power that it can’t climb a small grade unless I drop it into 1st gear. Yet, once on the level it will return to the original RPM. (Maybe it will eventually not regain the RPM but I haven’t waited that long yet before putting it away.)
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.
