RE: 5 mpg....why?
The map sensor is the sensor attached to the front of the throttle body. The throttle position sensor is attached to the drivers side of the throttle body and the idle air control IAC is attached to the back of the throtle body. The intake air temperature sensor is mounted into the intake manifold toward the front left top side.

RE: 5 mpg....why?
Good suggestions have already been made for checking O2 sensors, plugs, wires, etc.
However, I can make a 2nd Gen Ram
in 'perfect health'
get 5 MPG
just by accelerating hard all the time.
At full throttle and low speed my aftermarket trip computer shows 3 MPG as the instantaneous MPG.
The best way to see if the truck is 'sick' is to do a test at a steady 60 mph on an interstate. You should get at least 17 MPG from gas station to gas station if the wind is less than 7 mph.

i get about 13 on the interstate at 65 m.p.h. and thats my sunday driving; if i do the friday night crazy driving i am lucky if i get9 m.p.g.
and in the city maybe 5 like him maybe 7 if i could find a hill to coast down. LMAO
i think i have a bad cat, it rattles and everyonce in a while i hear a popping noise from the truck like it is cutting out and exhaust is being forced out of the system. what do you guys think ?

I'm a bit suspicious of the shop "soldering" the connections on your 02 sensor.
My experience in the parts business tells me you shoudn't do this as the O2 sensor takes ambient air temp readings from the connector and soldering wires messes with the sensors ability to read that. Could be a bad convertor too, but I'd replace that 02 sensor with one that doesn't require a connector replacement. The closest thing to a mass air sensor is your Map sensor...I doubt that caused your issue.
