I have a Grand Cherokee 2004 and was told it needs new spark plugs. I really want to do it myself but not sure if I should? I bought 8 of the required sparkplugs and have the wrenches needed but not ignition monitors and any other gadget, also I have never changed sparkplugs on a car newer than 1980.
Please suggest if I should try doing it myself if yes the steps required, thanks in advance, Subash
