DIY fix is the least expensive . Plugs , boots , perhaps a coil or two . Price varies too much for me to say . $3 to 8 per plug , Boots ? Coils $ 35 to $100 each . Get your codes , tackle those first . Go from there . Buy a cheap code reader at least . Then if you have your work "done" you at least know you aren't gettin screwed !

With a Chiltons , Haynes , or a buddy with a twelve pack ,, easy! You need to do some research before trying . Not so hard , but a few things to watch for . A " newby " can do it . Just research it first ! Good luck .

A severe miss can cause damage . Fore an example , I just did $1200 worth of work on a Toyota because of a misfire . Ford is better about protecting engines , BUT , ! I do not advise driving any distance with a miss.

Guess I'm the only guy responding to you . Sorry . Multi miss . Ck fuel press , filter exct . Ck for vac leaks . Could have dropped a few coils ? wiring ? don't see a lot of harness issues on these or sudden multi coil ,plug failures . Ck fuel quality . Maybe a tank of bad fuel or E85 , if not a flex fuel . Jersey had a problem last year with too much Ethenol in the fuel from one distributor .
