That sure sounds (no pun intended ) like some sort of an oddity... That could be caused by a fault in the radio or by radio electrical feed. Can some one with radio knowledge chime in with this info?

My theory that your ECU feed is also faulty and your ECU gets reset intermittently. Then, EVAP gets triggered during the test, because it takes the longest to get readiness reading.
