I've had P0171 and P0174 for some time now. I think those are related to a vacuum leak and I will be changing the CCV and the intake manifold gasket later this summer.
The last few days, I noticed that my secondary air pump was "whining" so I got a used one off eBay and took care of that.
I checked the codes today and I'm now getting P1635 in addition to the P0171 and P0174.
Any thoughts on what's going on here?
If it makes a difference, I just put spacers on the car. That's the only thing I did differently.

What is causing code P1635? I can't find anything on what this code could be.
