Need new O2s Bosch or AC Delco?
Need new O2s Bosch or AC Delco? Like it says, which should I get? Will I foul the new ones by driving it around for a week or so before I get my tune. Mods are in sig and the cam just went in Sun afternoon. O2s have been shot for weeks, codes 1133 1153, car won't idle and I think the bad O2s are making it worse, but I don't want to put them on and ruin them before I get my tune on Aug 2nd. Please Help, thanks in advance.
I don't trust the Bosch to work reliably. I'd spend the extra bucks on the AC Delcos.
As for fouling, it depends on what's going on. A week probably won't kill them - if it's only running rich. Assuming you're not dumping coolant in to the exhaust, and don't have any other weird problems, they should be OK.

I put 2 new Bosch O2's in my car when I put the new motor in. I got them for $60 each from NAPA Auto. I have had no problems with them fouling out and I am running leaded race gas. When/if they do ever fould out I will just spend the money to replace them, but I've been racing with them now for 3 months. I would recommend the Bosch.

I wouldnt go with either actually...
I would go with the Denso 02's that are lead resistant...they seem to be a more heavy duty, live through any lead/antifreeze or other crap that might get into the exahust (a blown head gasket can take out an o2 etc or you can run race gas)
i got mine off www.sparkplugs.com

Another vote for the Denso O2s. The part numbers are at the top of the list. There is a left and a right or a universal. The difference is in the length of the wire.
