Cylinder 2 misfires / had vacuum lines on wrong for 5miles. The code came up camshaft sensor . And p0302 is now the only code

Camshaft Position Sensor was an easy replacement on my prior 3.0 V6 so I don't think it would be much different for the 3.2. You could try switching sensors (there would be one on each bank) to confirm whether there is actually a sensor problem.

Check all the easy stuff air filter ect. I once had a mouse build a nest in my intake box on a weekend and man am I glad I had a good filter in the car.
not sure if that helps. but always check the easy stuff 1st.
