Default O2 Sensor question(bosch 13111)

I recently removed my Pacesetter LT's to put the factory Headers back on my 98 Formula. I had the Bosch 13111 O2's for the LT's, ran fine for the 12k miles the headers were installed. Will swapping back to stock manifolds and using these O2's make them act differently?

Im asking because my Bird idles fine now, but sputters slightly after giving throttle, itll balance out and run fine. It does it in park or driving. Any help would be great! At 70 bucks a piece, new front O2's would break the bank if not needed.

Thanks for looking,
Chris

O2 sensors don't care what they are screwed into, use them. They are a pretty simple devise, power/ground for the heated side and signal and low reference/ground on the other side. As long as they get hot and the signal switches they are good.

I bought the 13111(Long Vette O2's) because I put LT's on the car last year when I bought it. I did the pacesetter "extensions" and ruined two of my O2's which is why these are back on with stockers.

Its stumbling only when given throttle, every time. It only stumbles right after the throttle is pressed. I thought it was a vacuum leak so replaced all the intake gaskets, swapped the EGR with a known good one, still no change. Im stumped!
