Yesterday we driving along and all of a sudden the rpms dropped and the engine started sputtering/shaking very bad. Like it was starving for fuel. Pull over, the car will not rev up. I open the hood and it just reaks of gas. Didn’t see any leaks. We had it towed to the local dealership. What it the world could this be? Anyone else had this issue? It has 48,000 miles on it.
