What causes a f150 to start in high idel

What year F150? Newer? Is it cold right now where you are? It is normal for most fuel injected, computer controlled engines to run at higher idle speeds in colder weather (kind of equivalent to a choke) It helps warm up the engine faster. As long as the idle speed gets close to normal when the engine is warm and no lights are on, I wouldn't worry about it!

Nearly stalls on start up and at low revs

If you have what is called a "common rail diesel" I suspect that the diesel pump is not providing sufficient pressure for the system at low rpm's I would suggest that you have the pump pressure tested by an accredited diesel pump shop . The faster you spin the engine then the higher the pressure generated by the pump.

My nissan sentra 2.0 sl 2007 model, when its cold i start its engine for about 10min before i drive, the problem is when i press the gas pedal and then reach 2.5rpm the speed still in 40km/h but after a...

cars are programmed to shift at higher rpm to allow parts to warm up quicker and not stress the engine when its colder - not sure this is what you are asking

I turn on ignition and vehicle starts to idle real high seems like accelarator cable is sticking

Hi Clucas, If you're talking about a cold engine, the vehicle is fitted with an automatic 'up idle' system. Depending on how cold the ambient temperature is. The colder it is outside the higher the idle, until the engine reaches normal operating temp. The engine should then settle down to the correct idle speed. If however the cold start raises the speed to more than 1350, have a scan carried out. If the idle speed is always at a high rpm, do the same.A leakage of air into the intake manifold can also cause the latter problem. A leakage however will not be evident via a scan.

100 degrees is the normal operating temperature for the motor. If it goes higher than that, the thermostate needs to be replaced. The temperature will be higher on the highway because the engine is producing more heat energy due to the higher load on the motor. Diesels idle cooler and the engine will cool down at idle or lower speeds. That is why it is best not to idle your car for long periods of time because this will cause deposits in the engine and glaze the cylinders. The engine is working normal from what you described and there is no reason to worry. I hope this helped.

What is the oil weight for this car?

You don't say if you have a gasoline or diesel engine. For the diesel I would recommend Shell Rotella 15W-40 oil. For gasoline engines I would recommend a 10W-30 or thicker. (The larger the number the higher the viscosity.) If you have high mileage you might want to use a 20W-50 oil, but in colder climates you may want more like a 5W-30. Sometimes the oil cap has the spec printed on it.

My xtype 2005 estate diesel has some electrical fault somthing is draining the battery to nothing in two hours tried heater plugs NO tried new battery NO

Hi the most likely cause is the altenator 1 way diode has failed and is draining back through it, if you carefully touch it it will be warm when the engine is cold,there are lots of other possible causes ,you need to get it checked by an electrician sooner rather than later.could be as simple as a bad earth.

Engine idles high when first started after tune up and takes long for kick down

Hi edsan 58,

Most gas injected engines run at a higher speed when started from cold....It's the cold start application working....As long as the idle speed returns to normal within a minute or two....longer when the weather is colder.....nothing to worry about
