Customer Question

I have a 2005 Buick century that shudders when driving at slow speeds, like when moving into a parking spot, or driving at 35 MPH with the cruise control on. It does not do it when the vehicle is shifting. Our mechanic ran a diagnostic and found nothing, he cleaned out the throttle body, and changed the air and fuel filters. The car still shudders at slow speeds?
JA: Is the fuel filter an external one, or is it inside the tank?
Customer: External
JA: Are you fixing your Century yourself? What have you tried so far?
Customer: I have not done anything. it has all been done by an ASE certified mechanic.
JA: Anything else you want the mechanic to know before I connect you?
Customer: this vehicle has approximately 117000 miles and last year had the transmission rebuilt.
