Question HXers - closed / open loop...

Hey guys,
Looking for some input from fellow HX drivers. I've got a 2000 HX, 146k miles, 5spd. Recently tuned up / caught up with maintenance that previous owner lagged on (including cleaning the EGR chamber).

My ? - once warmed up, does your car go into open loop when cruising? Outside of lean burn of course. I have an ultraguage and on other vehicles, once warmed up, it stays in closed loop unless I go WOT or coast. On my HX, it will revert to open loop while cruising at times (outside of lean burn) with low/med loads.

Just wondering if this happens to other HXs or if its indicating my 5wire o2 might be going out...
