Hey, I not only got the code po1126 but also p1133 After getting a new MAF sensor installed. I put in a new dealership MAF sensor because I got a po1124 code. Now my 2002 porsche boxster works better now but still idles when the engine is cold and I run it over 3000 rpms. My guess now is that I have to change the oxygen sensors. What do you recommend?

I would check if the sensor installed is the right for the vehicle, or maybe the ducting has an air leak.
