1999 Daewoo Lanos SX is not idling properly even after I canges the MAP and the Throttle position sensors, what could be wrong?

Go back to basics
do cylinder compression test, dry and wet
if compressions 25 psi lower than another one this can cause rough idle(valves leaking)
should be 150-180 psi any lower engine wear.
check pcv hose from rocker cover to throttle body especially port in throttle body for blockage.
are any codes being set?
