Why does my car sputter when I Turn on the engine?

The fuel filter ‘s job is to filter the fuel going to the fuel injectors and then enter the engine. A clogged fuel filter can cause the engine to get too low fuel pressure or cause a clogged fuel injector. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter.

Why does my car have a white smoke smell?

If the white smoke is coolant, your car is definitely having a crack in the cylinder head or a leaky head gasket, along with a sweet smell. In this situation, you can pressure test the cooling system if the coolant is low or the engine has been overheating. If it does not, your vehicle is mostly having a leaking gasket.

Why do I have blue smoke coming out of my engine?

Look for broken or disconnected hoses and remove and check the PCV valve. Shake it back and forth to make sure it rattles lets you know it is working.

Why does my Honda 3.0L have no start?

If there is spark being fed to all cylinders, then you can eliminate the ignition system as the cause of the no start condition and can move on to other tests (like testing fuel pressure). Remember, the idea behind checking for spark is to see if all of the engine cylinders are getting spark.

Why is the throttle not working on my Nissan Maxima?

Maybe they are ‘sticky’ and needs lubrication. Also possible that one of the cables is tight and dragging the other, causing high RPM. As to the possibility of a fried ECU, it can be due to a shorted IACV stepper motor and, if applicable, electronic engine mount.

What causes the idle speed to go up or down?

The idle air control valve 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 causes a car to start at the wrong time?

Spark plug wires are a source of electromagnetic interference (EMF), but this is usually only a problem on some aftermarket setups when this interference isn’t taken into account.

What causes rough idle and car misfire?

Misfires often happen when your vehicle is under load while accelerating. This can result in slow or sluggish acceleration or a jerking motion while pressing down on the accelerator. A rough or uneven idle can be an indicator of an engine that is misfiring. The air/fuel mixture is disrupted which can cause the engine to jump up and down.

How can you tell if your car engine is misfiring?

Rough acceleration is a typical sign that your engine is misfiring. Sometimes, the engine will misfire on idle also; your engine sensors will get faulty values, and the air-fuel mixture will get messed up. This can cause a very uneven idle, which can jump up and down, and the engine may also shut off on idle.

What causes a car to stall at idle?

The way diesel engines produce power is different from gasoline engines. Every time the injectors push fuel and air into the chamber, the spark plugs deliver the electrical current. This keeps the engine running. If you have a weak or poor quality spark plug, then it is possible that it will lead to car stalling.

Can a car stall with a bad throttle position sensor?

The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time.

Why does my car stall at low rpm?

The will likely force your computer to stall the engine and only allow it to run at low RPMs, which means the car will only move at slow speeds. This is a safety feature enforced by the computer so that your engine doesn’t get too damaged.

Why does my maxima not accelerate when the RPMs go up?

If your Maxima won’t accelerate, but the RPM’s go up it’s usually not going to be an engine related issue. Somehow, the power that your engine is creating is not making it to the rear wheels.

When does the idle air control valve stall?

However, when the engine RPM drops below the normal range of 800 RPM (for most cars), it is more than likely that you are dealing with an IAC valve problem. In cases where this valve is clogged or is nearing its replacement age, your vehicle will stall instead of idling after the release of the throttle.

Why does my car rough 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…

Why does my maxima start at the wrong time?

If the engine’s ability to fire the spark plug at the right time is called “timing”. If the plugs are firing at the wrong time, or something has happened to cause the camshaft to no longer be in sync with the crankshaft, your Maxima won’t start. There will usually be OBDII codes associated with timing related problems, but not always.

What causes a car to crank but not start?

One of the biggest issues that causes a vehicle to crank but not start is ignition issues. When there is no spark, the engine will not start.

Why does my car idle at 700 rpm?

There is an air filter which prevents debris from the air from getting into the chamber. But if this air filter is dirty or clogged, then there will be less clean air passing through it. This will cause the engine to idle rough. Your engine should normally get to around 700 RPM after you start the vehicle.

What to look for when your car is idle?
