1990 245 Smog 200

235,000 miles, failed smog due to NOX over 2500. Put on a new cat and O2 sensor, NOX was 2999. Cleaned & tested EGR system, failed smog again.

Did a pre-test when the car was cold and would have passed. When the car is warm, NOX goes very high.

Now TPS is showing as bad, CEL is not on. Any ideas?
