I skipped over alot of this thread, i just read where it said you HAVE lost power.. I am here to tell you.... its your cats...... to prove it, take your pre cat o2 sensor out on the affected bank or both banks if you like, and drive it.. It will be loud but you will notice a power increase..... but...I bet 50 buxs its the cats.
