The results from the flow meter tests indicate what maintenance needs to be
performed on the air pump. Refer to the following table to evaluate the test results. 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
Guide (P/N 98295110) for rebuild instructions.
Note: Before replacing the pump head service cover be sure to perform any
