Time for an update:

Funny how things can happen and you never notice it because you are living with it daily... Allie drives the car and most of us with older Boxsters have had issues with vacuum leaks. We did a lot of testing and even made a smoke machine to track down and leaks in the engine bay.

The other day I was fooling around in the car and saw a red-ish square o-ring laying on the floor. It's broken and laying close the seat bottom where it was prolly kicked when operating the pedals. Well, I knew what it was from and now to just start the car and confirm; YUP brake booster/servo is bad. It's not easy to hear the vacuum leak when driving the car but at idle with radio off, the sweet sound of air being SSSSSSucked in is unmistakable. This has probably been a factor since day 1 and the diaphragm has finally failed enough to hear it easily.

We ordered a new booster for about $140 and will change it this weekend.

Moral of the story, if you suspect vacuum leaks and have fuel trim codes popping, then make sure to check the booster holds a vacuum. If not then you will have to replace it.
