Yes! Symptoms sound typical for secondaries remaining closed. Three usual possibilities: 1) the gearing inside the IMRC box is jammed/broken, 2) the linkage between the two banks of secondaries (under throttle body) has fallen off (as mine did...), and 3) the cable running fron the IMRC box to the secondaries has snapped.
