well, i was able to get a appointment at Baums Service Center which is my local vw garage. my jetta 2.0 with 76k has increasingly got worse over the last week.this is the first problem i have ever had with the car. the one morning i started it up and it started with a really rough idle. the entire car shakes from the idle. i have also noticed that the car takes alot longer for the engine to come up to temperature. im thinking it's some type of sensor but they are gonna hook it up to the computer to diagnose the source of the problem. i almost positive its something like that because the car ran perfectly fine one day then the next morning it started acting up. hopefully the problem will be taken care of... jus thought i'd let everyone know my story..
