Hi guys, Has anyone changed their O2 sensors on a 98 TJ, 6 cyl.? My check engine light has come on several times due to an upstream o2 sensor fault. I went ahead and bought both sensors. The new downstream sensor is too big to fit into the cat. Its a Bosch 13272. The sensor I removed has a narrow tip, it looks like the upstream sensor. The new one has a shield of some sort that will not fit into the cat. I searched the archives, some other guy had the same problem. He ended up getting the right sensor from the dealer and it fit, but its very pricey. Anybody have any info? Thanks. -Nick
