I would check for a vacuum leak, might also explain your mileage.

There are some vacuum lines under the battery that are famous on the 2nd Gen Rams for getting leaks due to fumes from the battery vents causing corrosion.
Another tricky to spot place is where the vacuum lines pass through the grommet from firewall into behind dashboard.
The 'blend door' of the heating and air conditioning system can also develop a vacuum leak that whistles inside the cab loudly.
