2010 Corolla LE - All painel lights turned on and the indicators are freeze

#1
Hi I bought a 2010 Corolla LE two weeks ago and on the second week with him, many painel lights turned on and the indicators became freeze. Also the engine is like if one cylinder is not working, but I already replace all spark plugs and ignition coils. I have no idea about what is happening. I heard about grounding wires, so I'll check all points today. Would anyone have any idea?
