The following table describes the flow meter readings for a new, rebuilt, or dirty
air pump in liters/minute. Perform all of the tests outlined in this manual and fill
out your results in the data tables on page 16. When you have completed all of the
tests, compare your results with the following table. If the flow meter reading is
equal to or lower than the dirty air pump reading, follow the steps outlined in the
action required column of the table. Pump head rebuild kits (P/N 79190003) are
available from Dynojet. Refer to the Air Fuel Ratio Module Installation and User
Guide (P/N 98295110) for rebuild instructions.
Note: If at any test point, the ball in the flow meter bounces erratically
(+/- 20L/min.) the pump heads need to be rebuilt. Pump head rebuild kits
(P/N 79190003) are available from Dynojet. Refer to the Air Fuel Ratio Module
Installation Guide (P/N 98295110) for rebuild instructions.
