Hello! I have a Ferrari 360. When starting my car it seems to be running very poorly. It also will very loudly backfire when giving it any gas. It did this once before a few weeks ago at a shop, but they did the ECU reset procedure and it fixed this issue. The car was good for a while, but it is now backfiring once more. Even after me trying the ECU reset procedure, the car is still backfiring and running horribly. My battery voltage is good as well. I have codes P1392 for timing sensor and P1530 for timing variator position not reached. I am wondering if this sensor would be responsible for the car backfiring. Has anyone experienced backfiring and the car sound poorly from their 360? Any advice is much appreciated. Thanks so much!
