Hello, Just bought a stick 03 350z with 88,000 miles. The car previously had a supercharger on it but blew the engine and has since been replaced along with clutch but is having issues such as sensitive throttle, long cranking time to start and trouble going into gear sometimes. The ecu is hanging below glove box and battery is poorly relocated into cabin behind passenger seat.I don’t know if the issues are possibly from a tune that is on the car from when it had the supercharger or if it’s a sensor or issues with the poor battery location.
