You will need to get a head check done to test for Co in the cooling system, if this is so you will have a head problem, this is a quick and simple chemical test that most work shops can do.

cam sensor has nothing to do with it.
check plugs, coils and do a compression test to verify engine problem.
a leak down test will eliminate a blown head gasket.
