Reported cause
I borrowed a throttle body from my friends car and swapped it and the problem was gone.
Leading evidence: 'gone' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'gone' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check car over' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt.

Even the best mechanic in the world isn't going to spend the time checking your car over that you will.

I'll do basic stuff like oil changes, checking coolant/fluids, brake flush/bleeds etc.

If you have Durametric, you can check the throttle position sensors reading.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I borrowed a throttle body from my friends car and swapped it and the problem was gone.
I was cruising along at 75 MPH and then my car went silent and I lost all power, however the radio stayed on....
I was able to get the car safely off the interstate and onto a frontage road where I recycled the key and the car started back up. Drove it to my mechanic and he said I had a throttle body code?
I am not sure if I should just replace with OEM or go the GT3/IPD plenum route. Has anyone had similar issues with their throttle bodies?
*All the little issues with this car are starting to slightly annoy me. However I bought the car as a "project" car and also recognized I bought a 13 year old car and parts do fail...
You do not yet know enough to start buying parts. The car dying on the road at speed likely means a lost of fuel or spark; buying a new throttle body will not fix either.
Did your mechanic clear the code? If so, bummer. If not, read it yourself and post the code(s).
A 996 moving at 75MPH with no power steering and power brakes that will be gone in short order is potentially hazardous - if you share the car with anyone and you need to continue using it, at least explain to them what to expect from the controls when the power assist is gone.
Is your car a C2 or a C4? If it's a C4, the fuel pump is much easier to access.
I would not rate "engine quits at speed on the freeway" as a "little issue," but I'm melodramatic that way.
Unfortunately yes, my mechanic did clear the code and I have no access to it now. Although I didn't have a CEL after my engine shut down. His first guess was my fuel pump but the code he got was something that was simply over my head and explained it as a throttle body issue. I have not bought any parts yet and the car is in my driveway... I was going to investigate my throttle body and fuel pump myself prior to ordering any parts.. However I have owned many modified cars and have never had an engine just shut off on the interstate before so this was a first. *bottom line is I am confused because no CEL came on after my engine shut down
And it is a C2 3.6L with 71,000 miles
If you have Durametric, you can check the throttle position sensors reading. I agree it's strange it could fail in such a way that caused the engine to shut down and yet you could restart it as if nothng had happened. The tricky thing is are you willing to keep driving the car to dagnose it further knowing that it may crap out anytime.
My mechanic did mention the throttle position sensor. However I personally am not aware of what that means? I get most terms for VW/Audi cars and can normally self diagnose but that one is over my head
It's a sensor inside the throttle body that detects the position of the throttle plate (in degrees of opening). There are actually two sensors inside working in tandem with the second one as a safety redundancy. If the DME sees something unexpected from any of the two sensors, at worst it will go to limp mode and control the throttle plate. It should not just shut down the engine.
My throttle body failed a few years ago. My car is Egas and started acting erratically. It would only get partial throttle, no power and some times no throttle at all. It came and went, and would seem to go away at times if I restarted the car. It finally gave up the ghost one day near my home, had to idle home. I forget whether I checked it with my Durametric or not.
I borrowed a throttle body from my friends car and swapped it and the problem was gone. Bought a new throttle body and never had the problem again. I still have the old one and took it apart. You could see how some of the electrical contacts were failing.
Make sure you shop around as the price of a replacement Aries a lot. Parts geek.com has a Bosch on sale for $201 right now.
If I really loved working on cars I would have become a mechanic. I prefer to drive my cars so I pay a mechanic. Just curious how much time the hard core DIYers spend working on their cars (and trying to figure out what is wrong) vs driving their cars? Anytime someone buys a used Porsche they should have upfront planned to spend at least $5000 in deferred but needed maintanece.
With this Throttle body and potentially a starter in my future I will be at $4,500 in 5 months of ownership.... so yes I plan to spend money and I drive the **** out of my car
For anything porsche has ever listed as being part of a "service" for the 996, not much time, and not much money. For anything where the engine has to come out, I'd take it to a professional, though.
It's like anything else in life, the more you put into it the more you get out of it. I've had as much fun tinkering and getting to know this car as I have had driving and tracking it.

When I was a kid (and had a garage) I was a little motor-head, so I sort of enjoy mechanical stuff. This doesn't mean I enjoy getting greasy to driving my car though. I try to schedule the big stuff for the winter so I can put the car up on stands and get it done at my own pace. I'll do basic stuff like oil changes, checking coolant/fluids, brake flush/bleeds etc. during the spring, summer and fall, but it's mostly driving/enjoying... Unless something breaks of course...
While it's true that I do love doing the work, it's also true that doing any accrued maintenance yourself gives you a chance to get very familiar with the car. How are those boots looking? Bushings? Is the body tray missing most of the plastic pop rivets? Let me jot down that engine number to see if it's been replaced...
It also gives you the opportunity to learn more about the previous owner. Pad wear sensors there but zip tied? Could have been an AX car. Pad wear sensors worn and then ghetto-fixed and zip tied up out of the way? PO was doing things on the cheap.
Even the best mechanic in the world isn't going to spend the time checking your car over that you will. Especially when it comes to driving events - or sending my wife and a niece or nephew out in the 996 - I'm glad to be the one to have done the work.
I think you can bet that everyone here on this site enjoys driving their Porsche.
A lot of guys, myself included, enjoy getting to know the mechanical workings of a vehicle, and the satisfaction that comes from problem solving and keeping the car on the road with their own two hands. I can afford to take my car to a mechanic but prefer not to.
As mentioned above, you also become intimately familiar with your car, especially important if you've picked a pre-owned one. I'm sure that more than few guys here could tell you stories of a car picked up from a shop and found shoddy work or damaged and broken items under the hood from leaving their car with the professionals. Yes, even the dealerships.
You obviously enjoy spending your time immersing yourself in the dealership experience with the coffee and cute baristas (who probably find your flirtations nauseating). That's great. But please do not just suggest for one second that DIYers are wasting their time.
Kurt,
John loves to use idiom or "devil's advocate" to get a laugh. Surely, you don't think he'd spend countless hours participating in Rennlist to insult people for the very reason that the forum exists.
I find most of his writings down right funny and insightful.
