what's up guys,

I just tried to replace my upper 02 sensor and have damaged the o2 housing trying to pry it off. That thing was on there good... Anyway the bolt housing is all scraped and I have tried to resurface it but the new sensor is not biting.

The exhaust mani looks all beat up anyway so I was wondering whether or not I should just get some headers.

Any advice?


...Also what is code 51??!

Thanks
