2000 kia sephia constant engine stalling!!!

My car continues to stalls at stop lights and when idleing still and or low. Recently I have changed both fuel filters in the gas tank and engine, installed new spark plugs and wires, bought a new battery, used gas/fuel treatment solution, changed the oxygen air sensor and manifold, and purchased and installed a rebuilt engine and tranny. My cars problem with consistent "stalling" continues to exist without any hope of resolution.

PLEASE ASSIST!

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.

Engine speed decrease when stert the AC

IDLE AIR CONTROL VALVE IDLE SPEED TOO LOW. IDLE SPEED SHOULD BE 750 - 850 RPM. IDLE SPEED NEED TO BE CORRECT OR IT WILL CAUSE ENGINE RUN ROUGH OR STALL OUT.AC COMPRESSOR WILL TAKE SOME POWER FROM ENGINE WHEN AC IS OPERATING.

Try running some fuel treatment in your fuel tank, if that doesnt help, try checking your spark plugs, It might be time to change them.
Good luck
