Help Request Posted
2001 Other European 360 Modena 218CID MIL Lamp on VIN: FERRARI360
P1634: unknown. Can anyone identify codes P1631 and P1634? Vehicle also has a missfire code, yet no miss is felt and car runs strong. The only thing a driver would notice is the mil lamp illuminated. I will have car back on friday.
