yes, every 4gen LS have this bug. The order of a new box is not neccessary. Thing is those drivers use high voltage to drive direct injection injectors. So, any dirt in the sockets, kinks in wiring etcetc will hinder it's performance.
Use plenty of electronics spray, clean the connectors and you're golden.

This happened to at least 2 ppl with LS4 i know. Now i know 3)
ps. don't expect in-depth tech advises on this board. mostly tire-kickers here and 'oil change solved my problems' people.
ps2. i hope you did NOT PAY OVER $50 for the ebay one! If it's more - return for a refund!
ps3. the reason for running rough after this dtc was set is not car malfunctioning, but rather ecm setting emergency mappings. When it happened to me, dtc reset on the spot made car run like it should. I didnt even shut the engine off, just hotplugged my Toyota IT2, read/clean codes, be on my way.
