O2 I believe to be changed 30-50K. Also I read on some other posts that people were having problems close to what you're having and they too were using Bosch spark plugs and other 'stangers recommended just sticking to plain old Autolite copper plugs (But I guess if you were using them before that wouldn't apply). Could there be a bad plug(s)? I heard of some coming from the factory like that, broken center electrode inside the ceramic.
