[QUOTE="jeepjoe43, post: 430557, member: 19255"] I moved it because I didn't see that the pipe wasn't drilled at it's bung until after I had it installed. Didn't drill it out insitu because I didn't want metal shavings in the cat possibly becoming a fire starter from the tailpipe. At the beginning of my bug hunt, I was investigating the O2 local, Chilton told me it was in the exhaust manifold, but it wasn't. There was a plug instead, so I assumed I had 2 sensors at the cat, and bought 2, so I now have a spare. Knowing it would fit there, and having a million other things to while I had access to a lift, I moved it. What difference would 4" make? Even asked my mechanic buddy and said None. Ignition misfiring will also cause the rich condition, she used to smell stinking rich ALL the time with the old O2 and exhaust. I'll be starting my investigation sometime this week looking for rat damage, looking at the plugs, wires, cap. A cracked cap can absolutely drive you bat-shit. Suppose it could be the CAM sensor, but there aren't any codes for it. It doesn't matter, replacing the distributor was already on my to-do list, just haven't got there yet. [/QUOTE]
