Tanzania had hopes of a first Africa Cup of Nations win after 44 years dashed when 10-man Zambia snatched a late 1-1 Group F draw in San-Pedro on Sunday.
Simon Msuva scored after 11 minutes for Tanzania, but Zambia overcame the red-carding of captain Roderick Kabwe before half-time to equalise on 88 minutes through Patson Daka.
Earlier on Sunday, Morocco and the Democratic Republic of Congo also drew 1-1, leaving all four teams with a chance of qualifying for the knockout stage.
Morocco have four points, DR Congo and Zambia two each and Tanzania one ahead of the final group matches on Wednesday in the Ivory Coast.
Tanzania were coached by caretaker Hemed Suleiman after Adel Amrouche was suspended by the Confederation of African Football (CAF), then fired by the Tanzanian Football Federation.
CAF banned the Algerian coach for eight matches after he claimed in a TV interview that Moroccan officials were influencing the appointment of match officials and kick-off times.
Both teams showed three changes after disappointing debuts four days ago in a group including shock 2022 World Cup semi-finalists Morocco.
Tanzania collapsed against Morocco in the closing stages when reduced to 10 men by a red card and fell 3-0 while Zambia were fortunate to draw 1-1 with DR Congo.
Since stunning the Ivory Coast in a 2012 final decided by a penalty shootout, Zambia have failed to win in eight Cup of Nations matches, and did not qualify for the past three editions.
