Black Taco Prerunner 03

3" Icon lift/Fuel Offroad 17"rims/Cooper Discoverer 285/R75/17/Spectre CAI/Boela exhaust

Had a couple ignition coils go bad resulting in my cat going soon after. (code P0420) I have a 03 Taco w 2 cats, ...370,00 miles...planned on replacing both cats next payday w magnaflow ca. compliant cats. After a couple days of sounding like I was driving around a rock tumbler it cleared and my check engine light went off. After hooking up my OBD reader it now shows NO codes. Why would my P0420 just disappear? Any suggestions?
