Default Multiple codes thrown

1997 D1
any help appreciated... 1997 D1 starts and idles just fine. When pressing on accelerator, sputters badly.

Any ideas?

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,
David

Washing a cat? Don't know anything about that.
Changing out the O2's is easier, IMHO.
I had to remove the ignition coil to get to the connectors on the sensors.
