Hi Sherri. Seems you’ve had a number of issues since the accident. Was there something you were wanting help with?

You’ll need to post the diagnostic codes for the folks here to be able to help. There normally wouldn’t be any relationship between the alternator replacement and the cat, so I expect that’s just a coincidence. Are you getting a p0420?
