Btw, A few months ago the car was having issues idling. In addition to this code I had another. I don't recall it but it did not appear obvious to me what to replace. I took a gamble and replaced the mass air flow and that resolved the issue. I will say that my fuel economy is not what it used to be in general. I am getting combined of about 18 - 20 and I used to do a bit better than that. Not sure if that's just a side effect of higher mileage but I don't know if that's truly the reason.
