I have an unusual problem. I don't seem to have much engine braking when I let off the throttle. For example: When traveling at 60mph I slip the transmission into neutral and the rpms shoot up to 3000 rpm and stay right there. As the car slows down, the rpms drop until they are at idle when the car is stopped! Obviously, there is probably a speed sensor that is affecting fuel flow. Anyone out there know what this could be? My fuel mileage suffers! Thanks.
