Can you do a log of fuel and ignition parameter data. I’d want to see your fuel pressures, timing stability, and fuel trims to start.
If the 02’s have 100k or anywhere near it then go ahead and replace as you need to for preventative maintenance anyways. Otherwise I wouldn’t recommend throwing parts at the problem based on the limited information you have, especially when the parts are going to run you 400+ for all 4 sensors.
