    Engine Question?

    I have 997S with 400 Miles on it now and have notice at idle I can feel engine twitch (ever slightly) every 3 to 5 seconds. Is this part of the Porsche engine character?

    Re: Engine Question?

    Do you see an accompanying variation in engine RPM on the tacho?

    It should be a smooth engine at idle. It is, after all, electronically controlled. In answer to your question, I would say it is not a normal thing.

    No, I do not see variation in RPM on the tach.

    A/C on or off?

    A/C off

    I don't have mine yet but don't forget the S has some hotter cams. You are going to feel a little loaping at idle. I used to feel it slightly in my 02 996 although the tach stayed pretty steady at just about 800 rpms at idle. I think what you are describing is normal. BTW, thanks for posting the sunlight pictures over the weekend.

    I have 450 miles on my S and I noticed the the same thing I thought it was the cam as well. Also notice a louder sound on start up much like the PSE is on but it quiets down after 5-10 sec. Now I will pay more attention.

    Re: Engine Question?

    Hey Guys, didn't you read some of the reviews where they comment on how an engine at idle (at startup? I forgot) sounds like a bucket of bolts shaking around?

    Apparently the thing DOES sound scary (in a bad way (bad meaning not good)) on the huge-number-of-parts-moving level.

    Should diminish when it warms up. Just listen to the exhaust note; pay no attention to the..., what would you call it..., maybe "heartbeat" of the engine.
