- 1998 Buick Park Avenue Ultra
I have a 1998 Buick Park Avenue Ultra 3.8L Supercharged. I am getting this really hard shake/shutter from the front end when I take off from a stop light. So when the car is at idle from a dead stop, if you give her significant throttle, it wants to pause for a second and then hard drop almost like the engine is slamming against the frame. Then shakes violently to tapering off the shake fairly quickly and starts to accelerate. I have been disabled for the last 5 years and I can't get as immersed into a problem like I used to. But I just cant figure this one out. This had to have happened to someone else I am hoping.
