I have an 1994 sc300, that I just purchased. The car idles fine. The car accelerates poorly. If I stomp the gass you would think the car would take off but nope. I feel no miss, and no slip in the tranny. If I give the car steady gas, I putt along until reaching about 40 mph then I can go. I gave the car a tune up, not sure what the problem is. The car has poor gas mileage, too.
