Hi Troy,

As far as the cam sensors, there are two. Each cylinder bank has one. See the attached pic.

A catalytic converter can cause a loss of power and limit the engine. Take a look through this link:

If you think the converter could be plugged, remove the O2 sensor before the converter. It wont be perfect, but the added exit will indicate if there is a problem with too much back pressure.

Also, have you checked for diagnostic trouble codes? This guide can help find the codes for you:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is. Let me know.
