Engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.

Had same issue with 96 camry with 3.0 v6. Tried all those things on speculation also. Found the timing for the rear bank was lined up with the tab of the timing cover rather than the timing mark! About a cm away. Adjusted cam timing, then within 6 months had both knock sensors fail.
