VSC TRAC a and VSC off and car with squiggly line and check engine Lights stay

What is your question?

I went to the dealership that they told me that the Cold they pulled up on the OBD2 Showed that some type of Pump that blows air into the engine was going badd and it would cost approximately $2300 to replace I believe the 2 pumps they were very vague at Lexus about the details Which makes me very cautious about pain $2300 for something I don't know Exactly what they're fixing This is on a 2005 GX470 NEED help

What makes this problem better or worse?

Never changes
