hi, to perform a tune up on this vehicle depending on the type of tune up you are doing, a full tune up will require the following: distribuitor cap,rotor, wires,spark plugs air filter pcv valve, fuel tank and fuel injection cleaner [ Sea foam, Techron,BG, ETC.], there is no fuel filter on this model, and no timing adjustment .
this does not sound right to me as this truck does not have a distributior cap or rotor
sorry my mistake you have a 3.7 liters engine distributorless with 6 coil on plugs
i mistaken you with a 1995 dakota i am sorry for the mistake.
ths engine has no distribuitor, it has a coil on each plug, this engine requires only plugs, air filter pcv valve and throttle cleaning, with injector cleaning. it will also be recomended to reset the factory values on the engine by disconecting and reconecting the negative side of the battery.
