I hated to use the word hesitation in my topic, because there are so many threads with that caption, but that is the crux of my problem. None of the other topics are quite the same description and they all appear to deal with slightly older models.
I have a 99 sc300. When I am running between 10-20 mph, the car will hesitate very slightly and then smooth out. It's kind of like a small lurch. It seems to do it more when going uphill. For instance, there is a RR track here that you drive down a small hill to get to and then up a small hill after you cross it. It almost always does it when accelerating away from the track and I'm usually at about 12 - 15 mph. This aspect is what makes me wonder if it is the fuel pump, or maybe just some bad gas.
Does anyone have any thoughts? I bought the car in February with 105K on it and the problems didn't start until about April. Any help is appreciated. I've currently got 107K on it.
