Recently acquired this sweet little beauty for next to nothing because the top got damaged. 67k and runs strong. Had to replace the tires due to age, not wear and next is replacing the top. But my question stems from the P0420 code that keeps popping up. Through checking the 02 sensors, and Cat, I discovered somewhere along the line either the Cat has been burned out or baffles were knocked out. I dont live in an emissions state so this is fine with me, but have been unable to find a solution to the code. Had seen on another forum about using a spacer to move the sensors out a little, but not sold on that helping. Short of buying a new Cat, has anyone run into this and found an economical solution?
