85 900t - High idle, drops when I plug PCV line

Hey guys
Still fighting my high warm idle. I've replaced the NTC sensor, tested the o2, cleaned AIC, threaded the dashpot all the way out and adjusted TPS and throttle stops. Was able to drop the idle back down to slightly more reasonable levels (I haven't been able to find any vacuum leaks), around 1100-1200 when at op. temps. What I found interesting in my search for leaks, was that when I plugged the PCV vacuum line, the idle dropped down 100-200 rpm. Does this indicate a leak somewhere in the pcv loop? Could it just signify that the issue is indeed related to a vacuum leak elsewhere? Could it be something altogether different (ie, AMM, ECU)? I miss driving a c900 and I'd like to get this resolved before I put her back on the road for the fall, so any help would be greatly appreciated.
Thanks!
