560 stalls when coming to stop
 

560sel 1990 model when i come to a stop from 30mph the car wants to stall. checked for vaccum leaks and none evident by sprayiing carb cleaner. so what nex? also when i turn the car ofdf the economy gauge pegs to the right off what does that mean?

When this happened to me in my '87, it turned out to be the vacuum line fitting at the rear of the manifold on the passenger side. Follow the vacuum line on the firewall toward the passenger side and you'll see where it connects to the manifold. Check the fitting and line for leaks.
