O2 sensors. The ones upstream from the cats. You can find them (NGK 25044) on Amazon. Priced reasonable. There's four under there. All the same part number. Two up stream are the ones that matter.

A lot of possibilities there with those codes. I agree with hrhoward though on the o2 sensors. I had the same codes recently, Code reader gave me multiple choices from plugs and wires to ignition coil, turns out it was a blown intake manifold gasket.

I ordered 2 new Co2 sensors.... I have replaced the coils, plugs and wires, VSS, Fuel pump...... A guy with similar issues says his 'y' pipe has gotten mucked up. He took it off and ran water from a hose through it for about 15 minutes and re installed and it helped his poor performance. Could this also be an issue?
Many Thanks,
