My 2004 CS seems to be a little weak to get up & go since I got it last summer, but still much more power than the car it replaced. I wrote it off thinking, "it's not a turbo, so what do you expect?" I did the plugs and air filters in the fall, and replaced the valve cover gasket on the driver side where it leaked the most. Still no major differences, not that I expected any. Went out to buy some throttle body cleaner the other day, and on my way to the store I got a phone call which prompted me to turn off the climate control (click the fan speed down to 0, temperature display shows 'OFF'). On my drive home the Cayenne drove *totally* differently. Really ballsy on the pickup, tons of pull. A few days later, I realized the car was especially chilly / foggy, so I turned the climate control back on. Sure enough, she was sluggish again to get going! Anyone see this kind of thing before, and know what might be causing it? As far as I know, most cars "back off" on A/C and heat when the driver calls for acceleration, but that's definitely not happening here. Also, with the colder weather I'm not sure whether the Cayenne is engaging the A/C in addition to the heat. Any insight would be appreciated!
Porsche is notorious for their conservative performance numbers when advertising their cars acceleration stats. That being said, they list the 997.1 Carrera 4/Targa's are going 0-60 in 5.4 with the tiptronic transmission. I've searched all over the net but cant seem to find a magazine which tested one of these cars with the tip trans. I know the car is way faster then 5.4 0-60 as I also own an infiniti G37s coupe which has the same peformance numbers claimed but my targa easily rips it by several car lengths to 60. Any idea how fast these cars actually are?
Hello all, I have been lurking around here for almost 2 years. I have a 2006 Cayenne S with automatic transmission with about 70,000 miles. This morning I went to drive it to the car wash. When I went to accelerate onto the autobahn the engine acted as if it were in limp mode. There was no power under load above 3,500 RPM. In neutral the engine will not rev past 4200 RPM. Here is what it is not doing or has been replaced - It starts and idles fine. - plugs and coils replaced last year less than 10 thousand miles ago. - I do not have a check engine light on. I am thinking: 1. MAF sensors (looks like a special tool required for replacement). 2. Throttle position sensor 3. Fuel Filters 4. Fuel Pumps 5. Or another sensor related to fuel pressure or fuel regulation/delivery system. Does anyone have any trouble shooting tips or advice before I give up and take it to the dealer?
