Did they fix the problems that you had with the car? I've been having the same problem with my car - it feels like it's "getting stuck" in acceleration if you know what I mean. I also have this strange noise (almost like a diesel) when driving in 3'rd gear and the rev is just under 3000...
Ok, had the car in for service yesterday and guess what? they couldn't find anything that was wrong?! Do you know what the problem was with the your engine? I will than try to forward your input to my dealer so that he know what to look for. Thx for your help
