One of the fuel injectors on my Audi 80 seems to be malfunctioning. How can I properly diagnose and fix this issue?
ReplyFirst, check the fuel pressure and flow rate at the fuel rail using a fuel pressure gauge. This will help determine if the issue is with the fuel injector or elsewhere in the fuel delivery system. If the fuel pressure and flow rate are within the recommended range, then the fuel injector is likely faulty.
If the fuel injector is indeed faulty, the most effective solution is to replace it with a new one. Be sure to use a high-quality, OEM or equivalent injector to ensure proper function and longevity.
