Aos?

2001S. 80k miles. Developed a P1128 and P1130 CEL code, couple days ago. Did some reading…possible AOS etiology. At idle, opened the oil fill cap…not hard to remove, but got an increased idle RPM, which then became “lopey.” As my kid said, sounded like I had a cam. Could hear some vacuum and, when I placed my hand over the funnel-like insert in the oil fill tube opening, could feel it as well. Yesterday (when the car was more warmed up) I did the same thing: got a greatly variable idle and could HEAR air rushing in. No excess smoke, ever.

AOS, open and shut case?

And, if “yes”, much as I’d like to work on this myself (NO time at present)…any problem with driving the car 20 miles or so to where I usually get servicing done?
