ATTN: all with WB 02 sensors... need some info

[Turbo V6 Camaro]

ummm can you tell me what you idle at? and does it jump araound alot?

mine is like 13-17 :eek:

unless the EGR leak is messing with it

[viper98885]

Yeah, it will jump around at idle and then give a good reading at WOT.

what does it read at idle?

The problem with idle is because the exhaust gasses are going slow so they cool down before they get too far down the pipe. The stock O2s are very close so they have no problem.

Unless the WB02 is in one of the stock O2 bungs, you can not trust its reading at idle. Mine is just before the cat (or at least where the cat was) and it gives false readings at idle. As soon as you get the RMPs up a little, it reads fine.

well in 1997's we have 3, and i put it were the one befroe the cat is....

even if i hold it at 2K rpms with HPT it jumps...... i think it's th EGR leak... time to weld it shut

If you are at 2000 rpms and the problem is still there, its not the sensor location.

They make block off plates. One for the exhaust and one for the intake. They are $5 each at ZZP. Might be beter then welding and mine have not leaked yet.

umm........ i know welding should hold better i thought if its done right........

the thing on my pacesetters is like bad and not smooth not much for it to seal on...

armma ma mmmmmmmmm

I have Pacesetters and used some high temp sealer with the block off plates and no leaks. I just hate to weld something and then a month later things change and you are stuck. I know if I welded them that is exactly what would happen. However, I'm just lucky like that. If you do want the plates, do not just order them off the net. They only list the one type and you want one of each. Make sure you call them. Good luck.

Cool, let us know how it turns out.
