I drive a '93 Subaru Impreza. Lately, my accelerator pedal will sometimes stop working while I'm driving, even while everything else seems to work fine, but will work again after about 2-5 seconds. It just kind of stops accelerating temporarily. This used to happen only once in a while, but lately it has been happening more frequently. A friend of mine said it might be the accelerator module. Any thoughts on this would be awesome!
