k, I spun the wheels with the engine running but no noticeable difference in number rotations compare to engine off.
Now I really don't think it is the brake because the tires rotate normally with engine on and off. In addition when I let off the gas and let the car cruise the car doesn't feel and the speedometer doesn't show faster deceleration.
So now I think the sluggish acceleration is due to the engine.
thanks
