When the problem first started out when there was a faint smell of gas in cab occassionally but now it has become much stronger and occurs every time the car is started. The fuems smell like raw, unburnt gasoline and the scent is coming through the air vents. My father took the car to our local dealership because a buddy of his works there and they had it for a week. No success. Everything I can think of was checked on the car, the torque of the plugs, the fuel lines, injectors, fuel rail etc. When you accelerate from a dead stop the car also has a gentle vibration until you reach about 10mph then it disappears. The fuel smell seems to dissapate as the car accelerates and is driven at highway speeds but returns at traffic lights. If this problem can't be corrected I think we are going to have to get rid of the car which is a last resort. Any help would be appreciated and thanks in advance!
