Engine Performance problem
1991 Toyota Celica 4 cyl Two Wheel Drive Automatic 257888 miles

Ever ince I got my car, it always made a puttering sounds as it accelerated. Recently its been havin problems accelrating. When I press on the accelerator it like chokes n starts making that puttering sounds n it rocks back n forth to accelerate. Sometimes I woudl push the accelerator ALL THE WAY DOWN n it would take real long for it to go faster.
