03 Catalytic Converter

Discussion in '2002 - 2005 Ford Thunderbird' started by 03TBird, Oct 8, 2017.

  1. Is there a way to find out if cats are bad, besides dealer? Car is sluggish when accelerating and can hear rattling noise on passenger side. After flush and refill of radiator, had upper hose burst, replaced but still sluggish

  2. Sounds like my '78 Pinto when I took the catalytic convertor off, broke out the catalyst honeycomb with a long screwdriver and put the case back in line. (Back in the day when there was a mandated but secret replacement guarantee)
