Stalls or Idles High or Low After Dead or New Battery
Engine Stalls After New or Dead Battery
Engine idle is necessary for proper
vehicle operation; it allows the engine to operate at the lowest RPM level possible
without your foot on the gas pedal. At idle, your engine produces the least amount
of emissions than in any other time it is operation. Even when your key is in the
off position the vehicle still utilizes electrical power from the
battery. The amount of electrical
power used is a very small amount; the battery can sustain this usage for many weeks.
But, when electrical power is completely removed from the system the natural memory
is erased. This natural memory is a result of an accumulative data that has been
processed and learned by the
computer. One of the
natural memory events is the engine idle speed. When the car battery is dead or
replaced this natural engine idle speed is lost. After the battery is replaced or
charged the engine idle will need to re-learn itself, this is normal. In some instances
this re-learn procedure is un-noticeable while others are quite noticeable. During
the idle-relearn period the engine will stall when in idle mode, but it is not unheard
of too idle to high also. If you have replaced or charged your car battery and now
the engine is stalling at idle, or
idling to high or
low follow the idle relearn guide below.
Step 1 - Engine idle low or stall: Once the new battery is installed
or charged start the engine. When the engine try's to stall hold your foot on the
gas pedal just a little to aid the idle speed. You will need to continue doing this
until the engine is warm. When the engine is at operating temperature the basic
engine idle setting will engage, the engine should re-gain idle properties. If the
engine is still not responding a short drive is sometimes required, both feet will
be used to perform this procedure. Put one foot on the throttle and the other on
the brake pedal. Continue this until basic engine idle is achieved
Step 2 - Engine idle to high: Once the new battery is installed or charged start the engine. Start the engine and allow to warm up to operating temperature. As the engine warms the engine idle should return to normal. If the engine does not return to idle a short drive will be needed. (Note: if engine idle is extreme do not attempt this step). Drive the car until normal engine speed is engaged. If further assistance is needed, our certified car repair technicians are ready to answer your car questions.
