The 33 is a EGR code the 49 is a electronic shift error the 41 is the 02 sensor lean code. Or that is on the KOEO test.

Techrep is thinking of the newer trucks. Your '90 is not affected by removing the cat, and those codes have nothing to do with removing the cat.

It's directly reading the engine, it is running lean or the sensor is bad.
