How long do SAI pumps last? The reason that I ask is because it's been louder than normal over that past year. Recently changed plugs, wires, valve cover gaskets, intake gasket, serpentine belt and purchased an Ultra Gauge. P1412 & P1415 are now showing. Checked all vacuum lines and ordered the SAI solenoid from A.B. I'm hoping that it clears, if it does not I'm guessing that it may be the pump? I have 49770 miles on our O3' Disco.
