How do you fix a 1988 Nissan Pulsar running rich?

Answer 1

To fix a 1988 Nissan Pulsar running rich, start by checking and replacing the air filter if it's clogged, as this can restrict airflow and lead to a rich condition. Next, inspect the fuel injectors for leaks and clean or replace them if necessary. Additionally, test the coolant temperature sensor and oxygen sensor, as faulty readings can disrupt the fuel-to-air ratio. Finally, ensure that the engine's vacuum lines are intact, as any leaks can also contribute to a rich mixture.
