Question about 1997 Kia Sephia
As you have replaced all the obvious things that could cause the symptoms it may be a good idea to have a cylinder compression test done , if comes back OK i'd try a fuel addative , one that covers the catalytic convertor , as there are many sensor's involved in the fuel/exhaust system as you know , this addative will clean any residue affecting there reading's , hope this helps

How many miles? I am NOT a mechanic! Sounds like possible timing belt/chain jumped a tooth. Or the timing advance mechanism is malfuctioning. (Unlikely - check distributor is tight or not shifted from normal position too far back or forward.) Assuming belt and not chain, 80 k miles or more, likely need to replace timing belt in any case, before it breaks. If it breaks, you'll be replacing valves and pistons too.
