CEL again, different codes
 

I had a problem earlier with a CEL and with the codes, P0107, P1126, and P 1133. I cleaned the MAF and drove 300 miles with no problems. Then today the CEL popped back on and the codes are P0410, and P1411.

I did a search and this has something to do with smog and cold starts, but it was 70 today.

I'm wondering if this could still be related to the MAF. The car runs fine.

Yup, could still be the MAF sensor. See this link here: http://forums.pelicanparts.com/boxster-cayman-forum/508433-boxster-cel-p1411-p0410.html and also Mike's MAF page also on that link...

I would try replacing the sensor - these things do have a finite lifespan.
