No, an engine idle RPM being not zero is not a problem. If the idle were zero, the engine would not be running!
The A/C uses more power, and raises the idle RPM
Around 750 rpm with warm engine and in gear.Around 750 rpm with warm engine and in gear.
It should be around 750 to 900 no matter what
When the accelerator pedal is initially released most computer controlled vehicles do not drop immediately to their low idle speed. There may be a couple reasons the engineers have maintained an increased idle speed, one of which is to make sure all fuel is completely burned, another is to allow the idle speed to decrease slowly to avoid stalling. I have also heard that there is some concern over valves warping if the idle speed drops too quickly but I can't confirm that one.
You cant...
The idle speed is computer controlled and is not adjustable.
The idle is not adjustable, it is computer controlled, which means the idle is not the problem. Look for a check engine light.
High RPM's in your engine which can be caused by a bad idle control motor, low transmission fluid, or bad hydraulics in the transmission, or maybe a bad gear.
adjust the idle screw on the drivers side of the throttle body turn it to the right to lower you idle turn to the left to raise it
my 96 dodge Dakota wont idle when engine is warm and i changed idle air controle valve what else could be wrong
Answeri Have a similar problem with my 96. But there is no way to adjust the idle. i checked chiltonbook.
