long term fuel trim errors 850 1996

This is possibly helpful info for others. I was getting recurring check engine lights for a few weeks. PO171 and P0172 error codes. Those are long term fuel trim too lean/rich errors. After changing out the vacuum elbows and soft vacuum lines, checking O2 sensor outputs, checking the MAF sensor output, and doing a thorough tune-up, I gave up and took it to a dealership. They found a hidden hole in one of the turbo air hoses. Why didn't I think of that???
