What are some things i need to get done to my 2002 dodge ram 1500 5.9l as a tune up. and about how much would that cost? and these are things that need to be done to keep my truck running well not like mods.

 

hmm.... plugs, wires, cap, rotor, chk brakes, tranny, radiator, suspension, steering, oil change, air filter, fuel filter, pcv valve, check anything that has the ability to wear out. ect..ect..ect...
look in you owners manual, there should be a place in there stating what should be checked/replaced/serviced at given intervals

or just take it to the dealer and have them do a good tune up /checkup

 

Flush the cooling system.

Change transmisson filter, fluid.

Spark Plugs if they haven't been changed in 30,000 miles.
