SEL 3.0L V6, Loss of power, rough idle. Replaced Cam Shaft Position Sensor (bank 2) per Autozone. Did not fix. 1. Should I replace bank 2 with the old sensor? I'm thinking not. 2. Would my next step be the Variable Timing Solenoid? Where would this be located, as I cannot find any diagrams for my car. Thanks y'all!
