Take off the air cleaner and hold the throttle plate open with your hand. Spray some carburetor cleaner into the throttle body. Try to start the car for 2 seconds.

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.

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 should the rate of revolutions be on an idle engine?

When you start your engine, and just let it run without pressing on the accelerator or putting it into gear, that is idling. A properly idling engine should be able to maintain a steady but low rate of revolutions, somewhere in the vicinity of 1,000 RPM. Your tachometer needle should be steady and not jumping around.

Why does my car idle but no check engine light?

This issue is normally caused by low fuel pressure or a faulty injector, but since you have just replaced the fuel pump, this may also be a sign of a failing idle air control (IAC) valve. This is a unit that is located on or near your intake manifold that monitors the air intake as it is mixed with fuel prior to being injected into the engine.

What to do when your car engine is idling?

Idling issues can be frustrating, but with some patient troubleshooting, you’ll have a real chance at figuring it out. Remember to always check your engine idle with the air conditioning and defroster turned off, as both of these systems are designed to change the idle when they are on due to the demands they place on the engine.

What causes idle speed to be thrown off?

So, one of the most common symptoms associated with a problematic idle air control valve (IAC) is irregular idle speed. Because, the (IAC); is programmed to regulate and maintain the engine idle speed at a constant rate. If the valve fails or has any issues, it can cause the idle speed to be thrown off.

What happens when a car starts and then dies?

You’ll hear the engine turning and everything will seem fine. However, there may come a point in time when your car will start but then die almost immediately afterward. This will aggravate you a lot because it will seem like your car should be working since you got it to start first.

What causes a car to run lean at idle?

If the root cause is an electrical problem within the idle air control valve itself, you will likely have to replace the IAC. A vacuum leak is a hole in a vehicle’s air intake system behind the mass air flow (MAF) sensor that allows unmetered air into the engine. This throws off the expected air fuel ratio and causes the vehicle to run lean.

What causes a car to die while driving?

Why does the engine stop working at idle?

This actuator receives information from the electronic control unit (ECU) so it knows at what RPM to keep the engine for a smooth and safe idle. When the actuator malfunctions, the engine gets no signal for idling speed and stops working.

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.

On deceleration, engine rpms may fall below normal idle speed and stall. When reaching a stop light, the engine may jerk and die. While driving, the engine may suddenly shut off.

Clogged Fuel Filter If the car dies while idling but restarts later, drive the car up and down a steep road to see if the problem persists. If the car still stalls, it is certain that the source of the problem is a blocked fuel filter. You can easily replace it though and it is pretty cheap too.

What causes a car to stop while idling?
