[QUOTE="BigAL07, post: 463753, member: 21619"] Just had a bout with the po430 code a few months ago. Went ahead and installed 4 new NTK sensors because I needed to anyway. They are heated by the way. Be sure to get the correct ones for your model. There is a link on this forum with the correct numbers. Still coded. Tried cat cleaner which is useless. Got tired of wasting money so I ordered 2 of the O2 spacers from the Walmart website and installed on the downstream sensors $15.00. Left the CEL on just to make sure they worked. After 3 cold starts light when out and has never came back on. Jeep still runs perfect. No emissions testing in W.Va so no worries. CEL lights drive me APE SH$$$. 🍺🍺 [/QUOTE]
