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.

I recently bought my first Porsche, a 2001 911 Carrera 4. It currently has abount 7,400 miles on it and has a slight vibration or engine stumble at times when idleing. Is this a normal Porsche engine characteristic? All my prior vehicles (BMW, Infinitis) would idle so smooth you could easily forget the engines were running. Nothing I have ever driven though even comes close to the 911 in terms of handling and power !!!
My experience is that these cars tend to be hard on plugs -- especially if they are driven hard. I would give it a tune-up first and then if the problem remains I would then start to think seriously about it. If it is under warranty still then might want to complain first and then maybe the shop will do the tune-up for you. S.
I have a '99 996 and my car is a little rough at idle, not to noticeable. I�ve heard that this is normal because of the cams Porsche uses. In my experiences the more aggressive a cam the rougher it idles. I wouldn�t worry about the problem. Also, I am curious as to what Porsche officially calls the new cars are they 911 or 996. I have always referred to mine as a 996. I think they started calling them that in '98 when they started water cooling the engines? Correct me if I�m wrong. I have heard them referred to both ways. I think I might have even heard them advertising a new 911 in a Porsche advertisement. Congrats on the Porsche sounds like a fun car. -Andrew
