When does the rough running occur? Does it happen at idle when the engine is cold or while driving?
Customer: replied 2 months ago.
My mechanic came back from vacation and tested it. It turns out that it is the lower catalytic convertor. $3000 for a car that's worth $5000. Does that sound about right?
Expert:  Richard replied 2 months ago.

That sounds too much. I would need the VIN to confirm parts pricing and availability but that quote seems too high.
