Do not buy the cheap no name remanufactured or rebuilt Acura RSX electronic control units, as in our experience most of these ecu’s don’t even work right out of the box. We also carry programmable Acura RSX control units from AEM that allows you to custom program your Acura RSX ignition and fuel system.
The Acura RSX Oxygen sensor is a critical part of the emmision control system and should be replaced as soon as it fails. Make sure to check the Acura RSX diagnosics codes for proper replacement of the O2 Sensor.
