Get the engine code then reask question to get a better answer. The Mass Air Flow sensor could be malfuncting causing bad o2 sensor readings also. Good luck.
The mass airflow sensor would be between your engine air filter box and the big engine air intake tube

A vacuum gauge is used to measure the pressure in a vacuum. Application for car is at the MAP sensors. Most fuel injected cars uses MAP sensors to provide instantaneous manifold pressure information to the engine's electronic control unit (ECU). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a mass airflow sensor (MAF sensor) to detect the intake airflow.
