Poor Response On Acceleration

Check for proper CO setting on mass airflow meter and for broken filament. Check mass airflow meter resistance.
Check induction system. Check for air leaks downstream of throttle valve, using pressure tester. Pressure should be 5.8-11.6 psi (.4-.8 kg/cm² ). Visually inspect between mass airflow meter and throttle housing.
On 900 Series vehicles equipped with catalytic convertors, check idle speed and pulse ratio.
Check injector operation and opening duration. Check injectors for leaks.
Ensure fuel pump is operating. Check fuel pressure and pressure regulator. Check for leaks or restrictions.
Ensure electrical harness, connectors and wires are not broken or loose. Check all input signals to ECU.
Check temperature sensor operation.
On 900 Series, check oxygen sensor resistance and voltage.
