Bosch Oxygen Sensors

I bought two front ones for my 96 z28 last week that will be going in with my new pacesetter longtubes. I just heard though that people have a lot of problems with the bosch O2's for our cars....any truth behind this? should i return them and try to find some ac delcos?

I thought they didn't take readings as fast as the AC delcos?

i'm running the bosch 02's and my car surges and hesitates slightly . don't know if that's related to the 02's but I am going to replace them with ac delco's shortly.

Replacing mine (Bosch) with AC Delcos this week. No real reason other than they are the OEM parts.

i did a cam swap and long tubes and put in bosch o2's and have a real bad high rpm miss/stubble could the o2's cause it. i have replaced the opti and coil and checked timing chain out of ideas.

good question, I kind of wonder this myself as I have an intermittent like problem, but I believe the answer is no. It is most likely ignition related, but I could very possibly be wrong....
