Warming your car up especially in cold temperatures is a good idea as the oil is thicker than normal.
3 or four minutes should be sufficient to see the temp gage start to rise and you should be good to go.
Assuming the car is a gas powered vehicle, and not a diesel the answer is, just long enough to get all the snow off the windshield. You don't need to let the car idle before driving it. The only reason to let it idle before driving is to defrost/defog the windows.
Fast idle motor is not working. This is allowing the idle to fall below the threshold of what it should be when the A/C is on.
It could well be the Idle Control Valve Or in other terms the Idle Stabilation Valve is faulty
Your idle air control valve should not affect your acceleration. As soon as you step on the gas , the idle part of your engine should not be operating. If your car cuts out or stumbles, i would suspect a problem with the TPS ( throttle position sensor.)
When the ac is running the idle should be raised to compensate for the extra load. If the idle isn't rising then the car will cut off.
It sounds as if you may have the timing adjusted wrong. The car should idle at 850 rpm I believe. If you adjust the idle the car should use less gas.
That depends on the car, theres a huge difference between a Hummer and a Pinto
Don't let your car idle for long periods of time.
no, you should let it idle and warm up a little bit.
when u first start the car it will idle high, around 1.5 rpm to 2 rpm. when its warm up it should idle between 700-1000 rpm
the ecu is reset when you disconnect the battery. after driving for awhile or letting the car idle in drive, your problem should be solved. the ecu is reset when you disconnect the battery. after driving for awhile or letting the car idle in drive, your problem should be solved.
A great way to adjust throttling on cars is through adjustments on your car's idle. A simple research on your car's manual should be able to give you the solution. Remember that the ideal idle for a car is around 650 rpm.
