Possibly blocked fuel filter, when you press the pedal it starves the engine or fuel causing it to cut out. Only a few quid for a fuel filter so I'd start there

make sure that your clean air intake is all hooked up correctly this is a common problem because when the mass air flow sensor detects too much or too little air it will try to die or idle rocky also if it is correct look to make sure the air filter is clean if not then replace it.

How do you adjust timing on a 2000 kia sephia


These have to be exactly right. Cannot be off even one tooth. After getting the belt on, always rotate the engine manually by the crankshaft bolt two revolutions to make sure everything lines up under tension.

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.
