$35 Vancouver car repair fix. The pedal stuck at the initial pressing. Mobil's page says not to use carb cleaner. ots of throttle bodies that are much harder to press initially from idle, but work okay all the way to full, after that intial "stick". Mobil's page says not to use carb cleaner. They usually say that because carb cleaner is a bit harsh and can ruin electronic sensors and the like. As long as you don't have any sensors or you remove them before the cleaning, you are fine.
