SOURCE: 2000 kia sephia constant engine stalling!!!

try this procedure and let me know if it cures the problem.

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Have a fuel pressure test done, that will show a weak fuel pump, or bad fuel pressue regulator, also have the throttle position sensor checked.
Could be the idle air control valve,
could be the fuel bypass valve.
Without checking and testing, it's hard to pin point the problem.
