Thanks for the advice. I've now run the proper proportion of Shell gas and Heet through my tank. No change. This has been going on for a lot more months than just recently. I've used all the major brands, Shell, Chrevron, Unical (I don't use Arco). No difference. I don't believe it's the gas. If it is, why isn't my wife's BMW M5 having the same problems? This is a Porsche problem that no one can solve.

Take a look at my posting. The dealer used the same "bad gas" excuse on me as "thelion" mentioned in his January 9 reply to you. A number of people are having this problem and since no service codes are triggered Porsche says there is nothing wrong with the car. Clearly a car that sputters has something wrong with it.

This car is a 6-speed No modifications Performing badly since at least early '05 Attempted to repair 4 times, kept it overnight a couple of times, no codes showed up in testing, and nothing's been replaced They don't know what the problem is but have even admitted to me that they have had other similar complaints

I purchased one of the first 997 CSs in Portland in November 2004. I have 8,000 miles on the car. I've had nothing but problems with the car stuttering, lurching and stalling from a stop. The problem is not always present and goes away after a few minutes of driving. It doesn't seem to be related to engine temperature, external temperature or gasoline used. I've driven M3s for the 8 years leading up to buying this car (my first Porsche), and have never experienced this before. After the first few minutes the car runs just fine. But I have to really feather the throttle and give it more gas for those first 3 minutes. I've stalled it a number of times pulling out in front of traffic. Very dangerous. And when it stutters and jerks it can be pretty violent (with sometimes a loud "thwack/thunk" from the engine). I first thought it was my driving abilities, but if that was the case the stuttering would happen all the time not just the first few minutes. The dealer (Sunset Porsche) and PCNA have not been able to fix the problem (which they think doesn't exist) and are not willing to replace my car (which is all I've asked for). Their attitude is basically live with it, we are not going to take care of you. Please help me if you can, as I had nothing but the runaround. I'm very frustrated. You expect more from a car that costs this much money. p.s. I'm also only getting 11-12 miles per gallon. I drive spirited, but not like a mad man. Is this a common experience? R&T got 16.2 mpg when they tested it and I'm sure they ran it harder than me.
