^ you can only do this procedure with a cold engine otherwise the SAP will not turn on. When doing this procedure it is vital that for each fill you leave the engine on for no more than 5 seconds max or else the SAP will not turn on after the second and third fill.

If there is no noticeable whining sound coming from the pump on a cold start then its not working and you need a new SAP.

Before doing mine I had a list of 8-9 codes being thrown relating to o2 sensors, low secondary air flow, catalytic converter efficiency, and miss-fires on multiple cylinders. After replacing my SAP and the seafoam treatment all is back to normal

Oh and you should really look into finding a good trustworthy mechanic as you will pay a fortune at the dealer
