1997 Buick Riviera Q&A

1997 Buick Riviera Question: engine or transmission

when I'm driving around 10 mph-15 mph the engine shakes and it happenes again at 20-25 mph, is there something wrong with my transmission -
Answer 1
Rough running can be caused by a number of things. Is your check engine light on? Does it always happen under the same conditions? I recommend taking it to a shop to get a diagnosis. The more information you can give them about the conditions under which you experience the symptoms, the better off you will be. -
