For the last 7,500 miles I had ongoing MAF problems.
I cleaned the MAF about 3 times but I still had erratic idling (w/o CEL)
When I was on the track two weekends ago two buddies of mine with pretty much identical Boxster S and I all started on full tanks and when I had to re-fuel before the last run of the day they still had 1/4 tank left.
So last week I got CEL P0102 which I couldn't make go away and finally had to bite the bullet and replaced the MAF ($248 at ********************************az).
I noticed that after the MAF change my avg. MPG went from below 18 to 22
So now I figure that the MAF will pay for itself in about 6 months.
So the conclusion: If you have ongoing MAF problems, eventually simply replace the damn thing; your car will thank you for it
