1997 ram bogging/dying?

hey guys got a problem on my hands!! First off i changed the oil maybe 2000 miles ago and one guy told me i needed an engine flush, since there was some gunk in there. Today on my way home im idling at a light(never iddles perfect) and all of a sudden car dies out. Start it back up and try to drive and it chuggs and kind of dies. So i start it again and finalyl get through the light i was at and try to make it the 2 miles back to my house. During those 2 miles it would barley accelerate, bogging, and if i pressed the gas down hard it kind of backfire through the exhaust. I made it home but wasnt pretty. What do you think, spark plugs, timing??? not what i wanted to happen since i just put all my money into buying a motorcycle:banghead: ! Any help would be greatly appreciated

You might check for trouble codes. How is your fuel pressure? When was the last time you changed the fuel filter?

Just start with fuel and spark, check it out.
