There are many causes to low heart rate in unborn babies. One of the causes could be not enough oxygen to the baby.
The idle speed is factory pre-set, and no adjustment is available. If the idle is too high, or too low, you will be having other problems that will affect the idle. In cooler temperatures, it will take the engine longer to come out of fast idle, as the engine warms up to operating temp. If the idle is too high/stays at a higher than normal idle, then take the thing to get it repaired. Running a car in gear(automatic transmission) with a higher than normal idle, can damage the transmission.
As far as I've been told, the idle is set by the pump? So if it's low the pump might need rebuilding soon.
Low oil level or pressure Hydraulic lifter bad
Usually some carbon deposits are left clinging to the combustion chamber surfaces, these deposits are red hot and ignite fuel/air mixture after the ignition is turned off. This could be caused by letting the vehicle idle excessivly long or only using it for short low speed trips. some times it may be caused by too rich of a fuel/air mixture. If it is carburated, if the idle is too fast it will cause it to diesel.
low idle and uneven idle
There are a few things that can cause a low idle in a 2002 Chrysler Sebring. The fuel pump may not be working right, the fuel injectors could be old, or the car could be low on oil.
You probably have a low refrigerant level.
The battery light tells you the system is not charging, if it comes on at idle or low rpm it is likely a weak or failing alternator. The idle being too low can also cause it to come on.
95 eclipse has a low idle
Check the idle, if its fluctuating or falling than nomal. Usually, low idle causes stalling when coming into stops. Low idle, usually is due to dirty throttle, a leak in the vac hose, or a damaged MAF or IAC motor.
Check the Idle Air control valve. This lets air bypass the throttle body plate when the car is at idle or low revs.
It will idle as low as 600 rpm.It will idle as low as 600 rpm.
Why is that my idle is low what cost that to do it
Since it is starting from 0, the engine idle is low.
If the car is starving for fuel or air (low power at idle), the car will stall while turning.
try replacing the throttle positioning sensor AND the low idle air sensor
