High searching Idle - ZR-1 Net Registry Forums

well, since you have eliminated the outside hose connections, it sure sounds like the hard plastic curly-q under plenum hose has popped off. It goes to the gas tank purge solenoid. The leak is big enough to idle at 1200 rpm as you described. My car came like that and was the reason for my first plenum pull.

That's my guess too after reading Marc's summary of known offenders! Will know this afternoon when I get under there with my borescope..
