English Language Learners Definition of oddly : in a strange or unusual way. —used to say that something is strange, odd, or surprising.

not working, not active, or doing nothing: idle factories. The machines are standing idle because there are no spare parts. Idle also means not useful or not based on fact: idle speculation..

Slang aside, ‘WAP’ can also be an acronym for Wireless Access Point, which is a device that allows people wireless access to wired internet. So if you plan on using the phrase ‘WAP’ any time in the future, be very careful what situation you use it in and who you say it to.

Idling is when a driver leaves the engine running and the vehicle parked. Everyday in the U.S. millions of cars and trucks idle needlessly, sometimes for hours and an idling car can release as much pollution as a moving car.

Idling your engine could damage your engine’s pistons, decrease your car’s fuel efficiency, get you slapped with a fine, and hurt the environment.

But setting my environmental preferences aside, you can let any car idle with the AC on for a long time without doing any harm. As long as the cooling system is working properly, you should be able to sit in any modern car you buy and let it idle indefinitely. Or at least until you run out of gas.

In most of today’s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won’t feel smooth. Rough idle is easy to detect when you start your vehicle, and it may be dependent on the engine temperature when you start your car.

For a passenger car engine, idle speed is customarily between 600 and 1000 rpm. For medium and heavy duty trucks, it is approximately 600 rpm. For many single-cylinder motorcycle engines, idle speed is set between 1200 and 1500 rpm. Two-cylinder motorcycle engines are often set around 1000 rpm.

about 600-800 rpm

Among the potential underlying causes are vacuum leaks, EGR system malfunctions, malfunctioning oxygen sensors, dirty fuel injectors, fuel pump malfunction, faulty spark plugs, a faulty mass airflow sensor, or a faulty throttle position sensor.

Rough idle caused by spark plugs, spark plug wires or ignition coil problems. If you have a rough idle that is caused by either the spark plugs, spark plug wires or ignition coil, you will also feel it when accelerating. If these parts are bad enough to cause a miss at idle, it will continue to miss while driving.

The idle is controlled by the idle air control valve and if it cannot keep the engine idling it will keep trying to rev the engine up to compensate. A vacuum leak, sensor that has failed, or an EGR system malfunction could potentially be the cause of the erratic engine you’re experiencing.

Causes of a rough idle. Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.

How to Fix a Rough Idle

1. Drive the vehicle to a reputable service center that has a code scanner.
2. Place the transmission in Neutral or Park.
3. Start the engine and let it warm up.
4. Check the condition of each plug.
5. Reinstall the plugs and start the engine.
6. Locate the idle speed and idle mixture screws on the carburetor, if so equipped.

Often, your car shakes when idle simply because it’s time to replace your spark plugs! When yours are dirty or worn out, they fail to fire in the right way. If this happens, they’re unable to ignite the fuel located within each of the piston cylinders on time. As a result, your engine can misfire.

Sometimes the idle control valve will need to be replaced. A new valve and its installation will cost you anywhere from $120 to $500. The majority of the cost is for the part as it is very simple work for a mechanic.

If your car stalls when stopped, it could be air-related, fuel-related, or ignition-related. Incorrect air readings could result in your car stalling. It will usually fire right back up though. If there’s not enough fuel pressure from the fuel pump or from a blocked fuel filter, your car might stall at idle.

Dirty or Failing Spark Plugs – The job of a spark plug is to ignite the fuel in the combustion chamber. Therefore, if one is dirty or faulty, your engine will struggle to start and sputter when you hit the gas. A clogged fuel injector nozzle causes a car engine to shake and struggle to accelerate.

Positive Crankshaft Ventilation (PCV) Valve On some vehicle models, a stuck PCV valve can cause the engine to stall. If the valve sticks open, too much air will reach the intake manifold and cause the engine to stall during idle or acceleration. The valve is usually easy to check.

Overall poor performance As the PCV valve starts going bad, the performance of your vehicle will get worse. This can be exhibited by a buildup of pressure in the exhaust or the engine could stall out. The bad PCV valve may not close all the way, so oxygen may get into the combustion chamber.

Since the PCV valves play an important role in the vehicle, a faulty valve might affect the overall performance of the car. A bad PCV valve that doesn’t close properly might allow the entrance of extra air into the intake, which results in erratic idle and affects overall engine performance.

This can be from a loss of vacuum due to the hose not working properly because of a leak, the hose being pinched, or becoming clogged from buildup over time. A misfire will sound like the engine has a vibration to it is a sign it is not running properly.

Bad PCV valves can cause engine oil contamination, sludge build-up, oil leaks, high fuel consumption, and other engine-damaging problems, depending on the type of failure. That’s because most car owners don’t include the PCV system in their maintenance routine.

The pcv reduces the air volume thus the power used by the engine to push that air around. You should experience a slight power loss with the pcv delete. The pcv is routed to the intake (duh) which pulls a vacuum (slight) on the crankcase which lowers pumping loss.

While the crankcase tube is disconnected, you can attempt to spray WD-40 down into the tube. Leave the tube up to get the penetrator to the valve, thus cleaning it.

Car manufacturers suggest that PCV valves be cleaned or replaced after somewhere between 20,000 to 50,000 miles of driving. The valve is usually replaced during scheduled tune-ups, but depending on its type and location, you may be able to check, clean, and replace it yourself.

Pressure leakage from worn seals causes the oil to be forced down into the inlet passage and back through to the inlet filter. Typically you will get an excess of oil being blown out through the crankcase breather too as the cylinder head/rocker cover is pressurised blowing back down to the crankcase.
