injector screens, and pressure regulator.

1. Verify that TBI Setup Steps 1-18 above have been completed before continuing

2. Refer to the vehicle's service manual for the manufacturer's recommended PSI.

without flashing. This will clean the TBI unit and filter the particles through the

cleaning, and Vacuum gauge connections in the vehicle diagnostics chapter.

button until the pressure rises and then release.

8. Press the  button to increases the time, or the ▬ button to decreases the time until

the

Time LED display indicates 30 minutes. (Run time may be adjusted depending on

the condition of the vehicle’s fuel system.)
