Throttle "bumping"
OK, how do I explain this problem I am having...
When I first start moving my car in the morning I usually pull away very slowly just because I am usually backing out of my driveway and then turning around in the cul-de-sac. When I start going forward, and I get to about 8 MPH two things happen. First the doors lock, as they should, but for the last week or so my gas pedal kind of hops under my foot. It almost feels like the ABS on the brake pedal but it is on the gas pedal and is only one pulse. It started doing it just occasionally, but now it does it everytime I pull away after starting. It is a good thing it does it every time now so that the dealer can witness it (although I don't know if it has to be cold). Anyway, anyone have any ideas what this might be?
Oh yeah, and I got my 18 OEM's from the group buy. I will post the pictures of them on my Redondo as soon as I install my new tires!

Mine does it too, I first thought it was a tire rub as it did it when I backed out of my driveway onto the street, then turned the wheel all the way the other way and then took off. But it has also done it with the tires not turned, sounds like a flap thud or just a hit of something, who knows.

Guys- It it more noticable some days than others, and does it happen only once?? Mine is that way. Once it happens, it never happens until I re-start the car. And if the car is already warm, it is ever so slight.

As ppl said above, NORMAL.
It's very noticeable. If you start your car and roll over nearly 10 MPH, it'll sound. "thump" or "flap". And, it won't happen again until you restart your car next time...
Sometimes, my car won't have this sound if I turn off the engine in the gas station and turn it on later. But most of time, if my iginition has been turned off, I will hear this sound definitely after the next start. :devil:
