02 Alero Converter Code
Writing about an ongoing issue with my 02 olds alero with a 2.2 engine. The Check Engine Light is coming on. Originally, it was Catalytic Converter error and thermostat error. My mechanic replaced the thermostat and reset the code. The light came back on. Then the converter was replaced. Light went off for about 3 weeks and then came back on. After it came back on, ODB was scanned and the error was catalytic converter. Took it back to the muffler shop and they replaced the CAT under warranty. However, the light is back on and it is still showing Catalytic Converter. Both O2 sensors are new AC Delco Sensors.
Any suggestions on what may be causing this issue?
