I just had a question to whom maybe could give me a solution to my problem, I am not too savvy when to comes to classic cars, but do own one. I have a 68 SS totaly restored, but I was not the one whom did the restoration. My problem is when I go to lightly press my accelerator its sometimes goes to the floor, by itself! I def was frightened the first time it happend, but it seems to release after about a couple seconds. I checked the return springs leading to the carebutor to make sure nothing was catching under the hood. Only thing that I could imagine it could be is the carebutor, but it appears to be a new one, nor did I have this problem since I owned the car for at least 3 months now. I have asked other people and they can't imagine what the problem could be. Just seeing if I could get some idea's as to what it could be, or has it ever happened to anyone?
