i have a 99 fleetwood ltd. (customized deville)
mileage has dropped down to between 16 and 17 mpg
car has 145 k miles on it
as far as i know plugs have never been changed
is it worth while to get real expensive spark plugs for it??
will regular 4 or 5 dollar spark plugs do the trick??
recently pulled a code that said "multible misfires"
will changing plugs help that out??
what brand of plugs will be the best???
thanks
