Default Strange problem......

Hello! I'm pretty confident someone here can help me out. Thanksgiving day, I took the 930 out and ran pretty well. Then on the way back, I was in 2nd gear and it started sputtering. I shifted into 3rd and it was totally fine! The light ahead turned yellow, so I down shifted to 2nd and it started sputtering again. When I came to a stop, it just died on me. I'm able to start it, but it won't hold an idle....even when I tried holding the gas down, it would just die. I had to get it towed home......

I told my daughter, "There's nothin' like driving a Porsche....and there's nothing more embarrassing than being stranded in a Porsche, too"! hahahaha

Anyone know what it could be?

Thanks in advance,
Jason

Best initial guess: You've got a vacuum leak. Check all hoses, as well as the intercooler O'rings.

If you pass the vacuum tests, check your rear fuel pump. Both have to be working properly for your 930 to run in top shape.

In my case the problem was the Front fuel pump was working intermittently . But I replaced both Fuel pumps to be sure . Also check the fuel pump fuse and the 2 fuel pump relays , make sure their working prior to replacing the FPĺs . Relays are easy to check ( plug the suspected relay in the horn relay socket )

Just to update.....

I finally got around to checking some stuff. I checked the vacuum lines and hoses and everything seemed to be okay! I went in the trunk and checked the fuse box......#6 fuse was missing! You guessed it.....the fuel pump fuse! I can't even find it anywhere in there! LOL I replaced it with a 25 amp fuse and all was good! I haven't taken it out yet, but it idles and revs fine so far! Thanks for the help fellas!

I had something similar happen (not exact) a while back. I was driving in 3rd down the highway and the whole car shut off. Sounded like it wanted to turn over but it wouldn't. Turned out it was 2 bad fuel pumps, believe it or not.
