hello everyone just a quick question about this .....
my 4.0 drinks gas like its out of style , and i dont have a heavy foot , so i checked my sparks with a multimeter and visually and there not in spec .
i just got some new spark plugs and was wondering if its in my best intrest to change the ignition coil at the same time ( like changing the ignition wires )
on ebay theres some kits going for a good price and was wondering , is this all i need
please let me know befor i get started on purchasing things i dont need
