The converter will not present any kind of restriction at idle.
As jlaudio mentions, idle is going to be an open loop mode, and the car will use tables to match fuel and spark timing to density (from MAF data) and speed (engine rpm). Coolant temp is also a factor.
You need to know what your A/F is at idle. Sounds like it might be overly rich. This needs to be tuned to get it right, particularly with your mods.
