STUTTER WITH THE AC RUNNING

2002 Kia Optima

Engine Mechanical problem
2002 Kia Optima 6 cyl Two Wheel Drive Automatic 100k miles

dear family im back again, this time my daughter is having trouble. When she turns on the ac the car starts to jerk, stutter or sputter which ever word you want to use. I did notice that the ac doesnt get as cold as it used to be. The compressor stays running no cycling like it is low.

Hi sixdux,

If the idling speed is not low, then you check for charging voltage.

If the voltage is low, you might have insufficient power to run all the components resulting in stuttering.

YOU MENTION VOLTAGE CHARGE IS LOW < WHAT EXACTLY DOES THAT MEAN, LIKE THE ALRENATO IS GETTING BAD OR HAVE SOMEONE CHECK THE COMPRESSOR

Hi sixdux,

Alternator not efficient will produce low voltage at the battery, Check and see if voltage is between 13.5 to 14.5 while idling with no load.

A slipping belt could also cause low voltage at idling.
