Hey yall, I just got my first Mercedes, its a 1999 CLK430. It has 65,000 Miles on her and it only sent me back 18,000 out the door. I think this was a great deal. Now the car runs excelent durring the day, and the car has some miles on it, but I mostly notice this problem when it is particulary cold outside. When I floor the gas pedal (I dont usualy do this but I just got the car a week ago and I had to see what she had in her), it accelerates untill it hits the 3000 RPM and sometimes 4000 RPM level and hesitates there for about 2 seconds, stopping all acceleration and not to mention ruining all the fun. Im very worried at this because this is a very sporty car, and should be really fast with 4.7L V8 with 275HP. Please help me on any information yall have on this problem, and if you need more information on the car feel free to ask. Thanks!
