Car shuts off by itself after rough idle problem

Hard to mess up a MAF sensor install, two screws and an electrical connection, I guess they could have installed it backwards or failed to properly seat the connector. Anyway, good luck and keep us updated.

I've had a new Dealer installed MAF go bad about 3 weeks after it was installed so its not uncommon... I've experienced getting new BAD maf before so i know it happens from time to time.

if it's not the MAF, see my post on this subject over on Rennlist. a vacuum leak is a likely culprit (oil separator bellows, oil fill tube, oil cap, etc.)

Verdict is in: Porsche says it's a defective throttle body. They ordered a new one for my car which should be installed in 1-2 days.

They tried installing another new MAF sensor but it didn't help at all.

Hopefully the new throttle body fixes the problem because I DON'T want to have to go back to Porsche next week....

And they refused to give me a loaner car even though my Boxster has been in repairs friday, today and will be tomorrow!

I called Porsche North America to complain but they told me : ''each dealer is independant''

defective throttle body? we'll see......

i'm doubtful this will cure the problem.

I agree, very doubtful....funny if it turned out to be a dirty throttle body which could be fixed in fifteen minutes with a can of carb cleaner, so typical of a stealership

Well I really don't care because the car is under warranty anyways so it will cost Porsche a new throttle body.

I agree with the fact that they could of just cleaned a few pipes here and there and solve the problem; but if they are willing to put the throttle body under warranty I'm all for it cause my car is getting a brand new lung at 50 000 miles, it won't hurt performance

My only worry is that if this doesn't fix the problem they will have to keep my car longer and they are refusing to lend me a courtesy loaner car while the repairs are ongoing...

My CPO warranty specifically states that if a repair takes more than 24 hours I am entitled to free rental car.
