The injector wire being loose is a very MINOR issue when compared to a completely plugged up cat. The truck was showing a lean condition on bank 2, but it was also down at least 150hp from what it should be, as it was running SLOWER at high rpm than a stock 5.3L did 100% because of that plugged cat. There have been guys that have actually destroyed their engines because of a plugged cat.
The injector harness having come loose had absolutely nothing to do with the problem that was causing the misfires and poor running that was encountered when I updated the tune, as everything was connected properly. I've driven 50 miles before with an injector that was losing connection and it does run rough, but absolutely nothing like was experienced.
There at Rickords, connections were wiggled and checked all over the engine, that is likely when the injector harness was bumped and it started to work itself loose.
Go ahead and put the PLUGGED cat back on, the engine will absolutely have the exact same problems it had.
