I'm getting a "catalyst inefficiency code bank 2" on my son's 96 Z71 with a 5.7L engine. I was wondering if anybody had a way to actually check to see if the converter is bad or if maybe the O2 sensors may be causing the code. The converter is an expensive piece and I want to make sure before I replace it that it is the actual problem. Also which side is bank 2, driver's or passenger's???
