I keep getting a code for my o2 sensor 41 i think or 43 it talks about slow response. Anyways i changed my 02 sensor with a new honda one and i think it maybe that my ecu is bad. I don't want to spend a lot incase the ecu that i have is stilll good. Does anyone have an ecu from a 1996-98 civic ex with lows miles that they know is working? I want to spend around 50 -80 shipped.
