After six years of near flawless service my Boxster is having some trouble. Two weeks ago I noticed the car was occasionally idling a little rough when stopped. Mechanic said it was the MAF, replaced it. Got the car back and noticed it had trouble turning over every 5-6th time, mechanic said it could be the starter, maybe AOS related.
I then got a CEL P0446 (EVAP Canister Shutoff Valve (Function) - Below Lower Limit). This evening the car did not start the first try. It turned over the second time but it stalled after idling for 30 seconds. I finally got home and have two new codes P1124 (Oxygen Sensing Adaptation Area 1 (Cylinders 1 - 3) - Rich Threshold) and P1126 (Oxygen Sensing Adaptation Area 1 (Cylinders 4 - 6) - Rich Threshold). I just had the MAF replaced.
I am thinking it could be dirty fuel injectors. Any thoughts on this? My mechanic is only two miles from my house, is it safe to drive the car to him, or should I have it towed.
Thanks!
