GEO TRACKER SENSOR PROBLEM

1992 Geo Tracker • 340,000 miles

Replaced cat, and o2 sensor 2 years ago, replaced plugs, dist. Cap, hoses. Passed aircare 2 years ago. Now failed again, 2 years later thought it was egr. Cleaned it twice. Still failed. Bought new one. Replaced. Failed worse than with the old one. On the nox and the o2. What now?
