The radio will cut out and come back on. Stop at a stop light the engine dies and show a p2074 code. After I replaced mao sensor tps sensor and ignition switch. The car would act like it has a miss fire in two cylinders. I pulled the cam sensor and found oil leaking on it. I am going to be replacing the cam sensor today.

I thought my cam position sensor seal was leaking but after closer inspection I found it to be a leak from the PCV valve which sits just above the CPS. I took the PCV valve out, cleaned everything well and applied a liquid sealer to the PCV and reinstalled. No problem since.
