I'd really be looking at why you are getting the ambient pressure sensor code.

And in several decades of working on these cars, I am yet to see one lose all four O2 sensors at the same time…………..

Focus on the P0107 alarm code first, that might be causing all of your alarms (could be a lean mixture issue). Clear the codes. If just the P1126, P1133, P 1128 and P1130 alarms come back, look at the O2 sensors before the catalytic converters first, that would be my guess. I'm thinking you have a vacuum leak or preasure sensor disconnect somewhere.

In my case I went way too long before replacing my AOS. Since my car had over 210,000 miles on it (and I was under the car doing other work anyway) I decided to replace all four O2 sensors. I could have spent more time troubleshooting, it was probably the two sensors before the catalytic converters, but with that many miles on them it was a preventative maintenance decision.
