Ok all you guru's of the LS1 I keep getting the troublesome P0135 & P1133 engine codes on my SS. I've cleared them out several times now and after about 50- 80 miles they come back! No notice in performance decrease. I've search here and there on the net and keep coming to a dead end. the only thing I'm pretty certain of is there being thrown because of my SLP long tube headers. Now I've heard the rear corvette 02 sensors will fix this problem but I've also heard it won't. I've also heard that just having the codes tuned out is a good way to go too. I'm not too keen on the idea of spending a 100 dollars on corvette 02's just to have the same damn problem again especially considering no one can agree on what brand to use. Some say bosh is fine others say AC Delco. Now I've yet to have it professionally tuned and it is definitely on my list of things I'm having done. Any suggestions will be greatly appreciated. Thanks

Thanks man that's what I was figuring. Just making sure there wasn't another way. It needs to be tuned anyways guess that's the next thing on my list.

I actually have the same issue. I am going to try the corvette rear O2's (Delco PN#13111) (I also found them for 34 a piece PM me if you want the site). I have heard they are hit and miss when it comes to fixing the code.
