Off-Center Pintle
According to Deanna Sclar, author of “Auto Repair for Dummies,” the primary cause of a leaking fuel injector is when the pintle is not sitting on the fuel injector’s orifice correctly. The pintle is essentially a button that, when pressed into the fuel injector’s orifice, releases fuel into the vehicle’s system.

When fuel additives do not burn evenly, they often settle on the pintle of the fuel injector and cause leakage. In addition, built-up fuel additives can cause oxygen sensor damage, affecting your vehicle’s fuel level readings.
