I'm stuck at that point. Might need connecting to a DRBIII scanner to find the cause.

# 21 Oxygen sensor signal doesn't change (stays at 4.3-4.5V). Probably bad oxygen sensor
On early TJs code 21 could be for either oxygen sensor, you'd need a scanner like the scangauge2 to find out which sensor the code refers to.
# 24 Throttle position sensor over 4.96V
Did you wash the engine bay? The throttle position sensors don't like getting wet.
