    Rough idle inconsistent

    Got a question. But first...I just purchased my first Porsche. A 2002 C4S. Had 35k miles on it on it. Bought it from a Porsche dealer - as a pre-owned certified. It is in great shape. AND I ABSOLUTELY LOVE IT!!!! I'm 49 years old and never owned a sports car before. Didn't think I cared about speed, handling, etc. Wow, was I mistaken. Got behind the wheel of that thing, and don't want to drive anything else.

    My Question (which I realize is probably a stupid question, but..) is... The car of course has somewhat of a rough idle. That's not the problem. The issue is that the roughness of the idle is inconistent. Meaning, it has a cycle to it, where it is of a certain intensity for maybe three or four seconds, and then gets more intense for a couple of seconds, and then back again. Etc. I pointed this out to the dealer, and he said it was normal. But it doesn't logically make sense to me. Any of you know whether this is an indication of a problem, or the need for a tune-up, or ... ?? I also noticed that the exhaust is much more pungent - smells much more of gasoline - than, for example, our other car burning the same gas (that other car being an Acura MDX SUV). Not sure if this is part of the same issue/problem or whether or not indeed this is all normal.

    Any thoughts/guidance/etc. will be appreciated. Glad you are all here.


    Re: Rough idle inconsistent

    Thanks. But I should have added that this is very subtle. I don't think there is any visible rpm variation - certainly nothing to the level the link you provided describes. No stumbling, it isn't what I'd call a weak idle at all. It just isn't a consistent idle. There is a subtle variation in it that annoys me mainly because I'm concerned it means something is wrong. I've had friends in the car who tell me they don't notice anything. (I also should add that this is a tiptronic.) The real question is whether there should be any variation in the sound or feel (vibration) no matter how subtle.
