95 t-bird 4.6 ran poorly and smelled like rotton eggs all the time so I suspected cats are bad. Took them out and discovered that they were melted and plugged so i gutted them out completely (no emissions testing here). Runs better now but still poorly. Will the lacks of cats affect the oxygen sensors and cause it to run poorly still? About how much would new cats cost me?
