Misfires can damage catalytic converters over time and are not good for your engine overall. P0174 indicates a lean condition in cylinder bank 2. There are a number of possible causes but on a car that old vacuum leaks are a distinct possibility. The links below and Scotty's video point out some other potential causes.
