stumped

My firebird thrown the codes p0133, and p0153 which is o2 sensors bank 1 slow response. I bought two new sensors disconnected battery, an installed them.
The car started up seemed to run smoother for 2 days. Pulled in driveway lastnight and the light came back on. Scanned it and got same codes again. Wat else would cause this?

check the o2 extension wires for breaks, melting, or corrosion

Ok ill check them again they looked fairly new, I'm gona try cleaning the pins on them an put don dielectric grease on them to see if it helps. Would the coolant temp sensor throw them off? I heard gms are known for the sensor goin bad.
