okay i tried a search so we can skip me catchin crap for that....umm.. basically i have a cam/heads 98 ls1 with slp longtubes and I am having intermintant flashing of the service light, code says 02's....so i replaced them, 10,000miles same thing, replaced them again, and again in the next like 10,000 miles, this time I replaced them and the light came back after 200 miles? car is dyno tuned also...any idea on what the problem may be? any help would be greatly appreciated. thanks.

are they bosch? Lots of people have problems with them, search the site. I would go Denso, or at very least AC Delco.

If you are running extension harnesses, you might ohm them out and make sure they are good or just replace them. It might not be the sensors...

Also if you have used certain rtv sealants, they can damage o2 sensors. Just throwing that out there.

**** I was actually just thinking about getting a pair of o2 extensions from you guys, what you mean they can ohm the o2s out? Are the plug and play extensions not a good idea???

I was referring to making sure they are good. No broken wires, etc. You can use a volt meter to do this. The plug and play extensions are the best option. I wouldn't every recommend cutting and splicing the O2 sensors back together to make them long enough. Let me know if you have any other questions!

If the extensions are bad try caspers electronics.com they have what u need.

look for a torn wire, i don't think might be the sensors.

bosch and densos ran fine in my car

ok....the torn wires I could see could be the culpret, but the problem is they always foul out, so if it was a faulty wire it should happen once, i replace the sensors and that should be the end of it, in my case the sensors last like 20k and blow out(keeps happening).....Jon-were you refering to checking the voltage on the wires that come with the 02 sensors or the wires attached to the car that the 02's plug into? still kinda confused. thanks
