Suspected cause

I'm guessing the usual suspect might be fuel pressure, you could rig a gauge to the fuel rail and tape it to the window, then have someone watch it while you can reproduce the problem.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

I am finding that near the end of the exits on high G cornering that my 996 3.6 x51 motor hesitates for a half second while at full throttle around the 5K rpm range. Any ideas? Thanks!

POST 2Original post

I'm assuming this is on a nearly full tank, or at least very low fuel level is not involved? I'm guessing the usual suspect might be fuel pressure, you could rig a gauge to the fuel rail and tape it to the window, then have someone watch it while you can reproduce the problem. Are you running the stock tune? Loose FP fuse?

POST 3 / ORIGINAL POSTEROriginal post

Happens through the entire feul level range, more frequently the closer to empty. The tune is the Porsche European 100 octane programe.

POST 4Original post

Quotes source post: 9383199

Couple of ideas... 1) Run a fuel cooler. 2) The 100 octane tune detect detonation and retards spark to save the engine. While the fuel pump at the gas station says '100 octane' the fuel may be stale or the engine's octane requirements may be more than 100. Engines vary in their octane requirements. Also, engine octane requirements can change over time, almost always going the wrong way, that is requiring more octane. 2.5) Tied with (2) above you might try a bottle or two of Techron the idea being this will remove valve deposits, fuel injector and combustion chamber deposits and sensor deposits and all of the above could see improved combustion which could lower the engine's octane requirements. Sincerely, Macster.

Might want to look at GT2/3 and see if Porsche did anything special on the supply side
