Alright fellas, need some help.

I picked up a 2001 1500 4x2 3.9 v-6 for $251.00. Got a hell of a deal. Came with a tool box and tools.

Ive done the standard maintenance, oil, plus, filters, and fixed the odds and ends like 3rd brake light, added fog lights and 2 4 ft. cb antennaes.

Problem now is i appear to be getting ~8mpg.

Any suggestions on what to look at?
