1999 Dodge Ram 1500 Laramie 3.9L Poor Fuel Economy, MIL Lamp on
Posted to Chrysler Driveability on 5/4/2005 10 Replies

Quick qeustion for you Dodge guys. This truck runs normal,except for a rattling converter and poor fuel mileage. Question is ,can the blown up converter cause the poor fuel mileage? My guess is yes ,but would appreciate some confirmation. Thanks,Spencer.
