P1128 and p1130.

The cars has had a light for a while now and we've done several things to try and fix it. First cleaning MAF and throttle body, then eventually replacing the MAF. Each time the light has been cleared. It has returned a few days later.

After the MAF the car now drives and idles perfect though, it had a surging idle before then. So the new MAF has definitely affected the car for the better. I am just stumped by the return of a CEL again.

Car is a 2000 Boxster S with 91k on the odometer. No symptoms now that idle is fixed.
(Just to add, the AOS was replaced already by PO around 14k miles ago.)
