Will bad 02's rob horsepower?
 

How much can a bad 02.. or multiples rob HP?
Can they make a car that is susposed to trap 109+ trap 106?

I know for sure both my front 02's are bad.. and throwing multiple codes a piece.. car doesn't seem to run too terribly bad except it is down on power.. not much.. but enough to tell something isn't right. Car has also only trapped 106 with an m6 car.. and I have almost all of the bolt ons aside from ls6 intake and pulley..

can they also cause knock?

bump?

Probably only if the bad O2s are putting his trims positive and throwing off his af at WOT. I think.

Not sure about robbing horse power. I have heard that they make your gas mileage suck though.

Did you run 109mph before? You can't just suppose your trap speed, you could have a factory turd :)

Since you are for sure they are bad, replace them. Then goto the track and let us know the results. I would like to know aswell.

Car made 333rwhp after the headers, it was fine.

333rwhp and trapping 106? Don't believe so. https://ls1tech.com/forums/images/sm...ch/gr_jest.gif

If they throw off the LTFTs at WOT,then yes it can cause a power loss. I wouldnt expect it to make a huge difference though.

shit im getting 8 to the gallon, maybe its my o2s

Dunno, maybe your VTEC didn't kick in :chug:

Yes, bad O2's will hurt performance and hp. Especially if you're SES light is on (limp mode)

That's definitely another good point.

if the SES light is on, then you are probably losing quite a bit of power
