O2 sensor keeps going bad
O2 sensor keeps going bad What could cause an O2 sensor to keep going bad? I put new ones in Dec. 08 when I put my headers on, they're the Bosch 13111 ones. Nov. 09 the drivers side one went bad and now that same sensor went bad again around 6 months later. The code it's throwing is P0131. I've read that some times running open headers can cause them to go out pretty quickly. I've got an exhaust leak at the collector I haven't had a chance to get band clamps on yet but, It's not bad enough to cause this I wouldn't think. So what should I look at? Thanks.
