I have a 2005 996 TurboS 6sp with 19k miles. Car is in excellent condition. But I have only put 600 miles on it the last six years. Now it runs extremey lumpy and dies as soon as you hit the gas. Managed to slowly get the Engine up to 3500 rpms but then it dies. It idles just fine. "Check Engine" never came on. Porsche is at a loss. Car generates no "error" codes at all. We have run three different analytical tools. I also had a frieden who is an Electronics expert, run diagnostics on every sensor etc. No errors. Turbo charges and waste gates have been checked. Manifold and hoses have been checked for leaks. Car is now at a Bosch service center. Found no defective components nor indicators of any problems. They replaced the plugs and all six coils just to eliminate the ignition side. We are now left with the fuel it self and the cam sensors, eventhough there are no indication that they would be faulty. The Cam sensor is a huge job with gearbox having to come out. One more thing. Car was sitting with battery disconnected for many months before I started it up again. But it ran for weeks before the problems started. Anybody?
