the code could be because one of the mounting points came loose from the Sec Air hoses. Same thing happened to me.
Before ordering MAF and o2 sensors have you spoken to David at The Shop? You may not need these
Not yet. I planned to call John this week. I fixed the whirling sound. What mounting points are you talking about?

Just talked to Tech @ NTK and re: Amazon... they might have connectors, or not. But from authorized NTK vendors #25623 and #25624 always have the connectors.


Rockauto has them for still under $200 for 4 > $50.99 and $47.89.


Maybe someone who bought these from Amazon can give you more info.


As far as quality, I only use NTK O2 sensors/NGK Plugs on all my cars. I haven't had good results with Bosch in years.

I bought a used MAF sensor. Works fine.

So replacing the MAF sensor specifically fixed these codes?

Well, problem turned out to be O2 sensor on left bank (drivers side) AND water throughout the entire secondary air system, even in the check valves.

How do you suppose water got into the secondary air system? It was even in the pump.
