I need some help...

Do a Tune Up while your at it- Plugs, Wires, Cap, Rotor.
and don't buy the cheapest parts available to fill the hole.... last I checked (for example) the better distributor cap (brass inserts) was only like $2 more than the cheap one (aluminum inserts) and remember Mopars don't like Delco plugs unless you want a whine in the radio.. I have never tried Delcos in a Mopar, that I didn't have to change out shortly after for this reason.
