Headers and o2 sensors question Alright guys I have pacesetter longtubes y pipe and slp exhaust. I had some issues with the headers before the header bolts came loose and my o2 sensors blew ( the shop ran o2 wires too close to header and melted the wires blowing my o2 sensors) when all that happened my camaro would sit and run and sound like it was camming ( I don't have a cam ) so I got it all fixed ran wires better etc. It seems that it's starting to do it again almost same exact symptoms so I will try tightening header bolts but my question is, is it common for header bolts to come loose so often ? Is there anything I can do to stop them from coming loose again ?

Okay I found the stage 8 bolts. But also is it common for header bolts to do that ? The other thing with the headers will my o2 sensors constAntly blow (( if that's the problem ))

Manifold bolts will usualy need retorqued after a few heat cycles, yes.
Most peoe report New headers will ruin o2's after their first few heat cycles as some chemicals are released from the metal, specifically ceramic coated ones.. because of this most people wait to change them untill after heat cycling them..

ur o2s keep going bad? what kind are you putting in? and were your headers new and coated? maybe the coating ruined the first set and you changed them before you ran the headers long enough and they also ruined the 2nd set?
also it melted all your wiring... did it blow the fuse? or just ruin the o2's? maybe your fuse blew finally and wires werent quite fixed? you check the fuse?
o2 fuse is underhood, cant remember which one it is but it also controls the fans

Okay yes my headers are coated and I guess I should drive it some more to get threw the heat cycles and also I took it to Chevrolet so OEM o2 sensors were put it I checked the fuse just now and it is not blown so possibly it's just that try are still new headers I never drive the car I drive far for work and don't want to rack up miles on it maybe I should a couple days and get the chemicals and such out but I do know that this happened after I drove it for a couple hours one day going to a car show so possibly that caused it
