[QUOTE="Jerry Gerner 2, post: 917259, member: 67360"] I already replaced the elbows and line. Not sure which Cat it is that has stuff jingling around in it, either the front or rear, haven't taken them off yet. I was thinking about taking the Y-pipe off, cutting off those two cats and replacing them with exhaust pipe welded in. Taking the front main cat off checking it and replacing the rear cat with exhaust pipe (pretty much the poor man's RT exhaust). Will the O2 throw the PO171, all of this started after I installed the SD coil, Live Wires, and plugs (Autolites APP103's gapped at 54) could I have a bad wire, coil, plugs??? I'm not familar with newer emmission controlled vehicles, used to working on old musclecars. How can I check to see if the O2 is bad, how many are there and how much do they cost??:angry::angry::banghead::banghead::cry::cry: [/QUOTE]
