It could be a leaking injector, considering the rich condition on one bank.

One of the tuning gurus could answer far better than me, but would a leaking injector cause the ECM to consider TPS at idle & command the IAC to increase idle air to compensate for the rich O2 signal on one bank?

I don't see it causing the PVC Connector to blow off, which may or may not be related at all.

We do see a lot of bad, original injectors leaking in the 90-92 models.
