I am new to this forum. I own a 2004 996 turbo X50. My Porsche hesitates or stutter when I accelerate between 2000 and 4000 rpm. It maybe a coincidence, but this started to happen after I put gas in my car when it was almost empty. The car has 30k miles and just had the 30k service done. I tried to run the car hard several times, but the car still has the problem. Anybody have an idea of what maybe the problem?

Thanks

Plugs been changed?

 

They were changed as part of the 30k service a few months ago.

 

Boost leak? Have you checked all of the hoses?

 

No, I have not. I will have them check. I noticed the boost goes up and down and is not steady.

 

Check all of them, including the ones under the car connected to the turbos.

 

Sounds like plugs to me. Who did the service? Perhaps they told you they did the plugs but did not actually do them due to the effort and time required.

 

At least on paper they dealer is showing that they replaced the plugs back in Oct (see attachment). I bought the car from Pacific Porsche. Can the plugs go bad so quickly? Can I go back to them and claim?

Thanks
