Now that the cold weather is hitting again, I have a problem with my gas pedal. On colder days, if I take my foot off the gas, and go to press down the gas, it's really sticky and sometimes I have to press it hard which is a pain when shifting gears. It doesn't stick if I keep the gas pressed down a bit, it only does it if I let off the gas completely then press it down again. I had this problem last winter too and the dealer said he didn't find anything. What would be causing my pedal to stick like this? It doesn't happen on warm days.
