So,

My car lately has been running kind of rough, and I have had thoughts of floggin it off.

People don't relize that o2 sensors wear out just like spark plugs. Around 75k the primary one should be changed.

Chris - is that true if you have a test pipe and cat delete file, too? I'm almost at 75k and might replace it if so.
