I have a 2001 ram 1500 (5.2)318 quad cab and22 inch wheelsthat keeps shifting in and out of overdrive I drive 30 miles each way to workand it takes 1/4 of a tank each way with the cruise set at 70 it will stick the gas to the floor even on flat land it does it any thoughts? it has 102,000 miles and a fresh tuneup Thanks for any help!!!!!

 

My guess would be the TPS sensor. Wait for someone more qualified to give a better answer.

 

welcome to DF. i'd start with throttle position sensor (TPS). its on drivers side of throttle body. costs about $40 at any local auto parts store, but i recommend SMP brand. 60 miles per 1/4 tank is pretty crappy mileage, about 10 mpg. you probably have other problems too. i get about 13-16 mpg depending on a lot of things. make sure you are accurately measuring miles and caculating mpg with your big wheels/tires.
