Reported cause
New throttle body is installed and the problem is 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 'Disconnect except i have e-gas' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
So yesterday I was out for a short drive and had the surging, then it was almost as if the throttle had some disconnected, except I have e-gas.
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.

took my 2000 carrera out for a ride and it wouldnt go above 2k rpms (approx) i turned off the ignition for a couple of seconds and re-started and it was fine...for approx 30-90 seconds then the same thing would happen again, there were no cel's, no strange sounds or smells or anything, it seems perfectly normal except the 2k limit, its bone stock
any idea what it could be ?
I did have a throttle body electrical connector (located on throttle body) come loose that kept engine from responding to pedal input you can make sure that the rubber seal washer inside is not interfering to make good connection. I had a Durametric tester to see the problem.
I had a similar problem with my car yesterday. I have been experiencing some surging when the engine is not warm for many months, and sometimes it would set of the ABS/PSM lights. If I stopped and turned off the car the lights would go out. Once the car warmed up it would go away. So yesterday I was out for a short drive and had the surging, then it was almost as if the throttle had some disconnected, except I have e-gas. It barely revs when it neutral, maybe 2K or so, and when under load even less. Basically had to idle the mile or so home, it would go up to 1.5K to 2K. However, it does seem that there is some signal getting through as it does go off of idle. Also the idle is sometimes rough and at other times smooth. I am thinking the throttle body or the Electronic gas peddle. I haven't put my Durametric on it yet. I will try that tomorrow to see it it shows an error but there are no lights on.
Fortunately my best friend had the exact same car as mine, only difference is his interior is gray. I am going to swap out his throttle body for mine (a 15 minute job). If that fixes the problem I know what to replace. If not then I will try the pedal mech.
Mother - Waht did the Durametric show on your probelm??
The problem showed I believe "0" volts throttle or "0" for throttle position when trying to apply throttle in "Real Time" with Durametric not much help been awhile for that problem.
I think my 1999 is a cable drive linkage to the throttle body since I'm pretty sure I slipped the cable off over a year ago and had a simular experience. You might check to see that the cable is attached correctly. It should be tight on the wheel looking thing. If a 2000 is cable drive maybe check to make sure the conduit the cable travels in hasn't come loose anywhere. It has to be secured to allow the cable inside it to apply opening and closing movements to the throttle bodies butterfly valve. Or maybe the wheel the cable semi wraps around isn't secured tight to the butterflys shaft.
Well I diagnosed the problem with my throttle body. Took the one off my friends car, it is a 10 minute job at most (so a dealer would probably not charge more than 2-3 hours
) and put it on mine. Problem was solved. But can you believe it he wanted his back
So now tomorrow I am going to have to decide on whether to order a new one (list $333 so discounted about $225-$240) or try to find a used one. If the used is over $100 I will probably get a new one. Sure was helpful to have one to swap to assure myself that this was the problem.
I did a Google search and found a place that sells rebuilt ones with a two year guarantee,
for only about $100+ more than a new one from Porsche.
You have to be careful when you are looking for deals on parts.

try porschepartsnationwide.com for online parts - they are the Rector Audi/Porsche dealership. I am local (bay area) to them, so just order online and pick the parts up at the store.
Nice work Doug.
e-gas is a nickname for the type of throttle body (fly by wire) used in all 996's after 1999. Prior to 2000, the throttle's were cable operated (more better).
Funny though how they call if "fly by wire", when really it should be "fly without wire", or wait "fly by electronics". <sheesh>
We should all have an extra car around to swap parts with, wouldn't that be nice.
Just ordered a new throttle body with the new number 997.605.115.01. Did a little searching on the internet and by phone. Two wreckers wanted $150-$175 for a used one, and over $50 to ship it overnight. Lots of sources in the $233-$245 range but again the overnights shipping was pretty expensive, $40-$50 bucks. Pelican had it for $240 with only $21.89 overnight shipping. Then I found a source called KOperformance.com that had it for only $223.99 and was only $14.95 for overnight shipping, DONE DEAL! Ordered a couple of other things at what seemed to be great pricing to throw in the box at same shipping price.
I am on the traveling tomorrow but should be back on the road on Saturday
