civic ex doing a motor swap this weekend. just bought the car less then a month ago. person bought from said check engine light was on for 02 sensor he said he replaced but shortly after going through emission test light came back on with converter code. from what i understand this is pretty common. and if it is converter do the aftermarket converters work or will i still get a light like most cars with aftermarket converters. would appreciate any input thank you
