03 G35Sedan. Car blew the heater hose last week. Got it home, parked it and when I came back hard start all 3 lights on and a high circuit cam position code on for bank 1. I opted to try the auto parts store first and bought the sensor from there. Installed it and did ecu Reset and relearn procedures. Immediate start and no rough idle, but under acceleration it bogs down hard and the rpms will stay in the same spot then shoot Up and the car will accelerate a little bit. Any advice?
