fi cleaner will be a good start.
Depending on where you get your gas will depend on how "clean" it is.
Injectors WILL start to clog and gum up.
Ive seen a lot of abused cars as far as neglect to keeping carbs and injectors clean.
Some times, not always, but some times, a good cleaner will save a butt load of cash
on new injectors.
Ive made some good cash on folks who dont believe in fi cleaner as a preventive.
Along with folks that dont fix their breaks when they start to squeak.
(injectors and rotors aint cheap)
I run Lucas about every 4 or 5 tank fulls.
Ive used just about everything under the sun for fuel additives/cleaners
and this has been what Ive used for many years.
Everything from stroker motors with 750 Hollys, CB, KZ, Z1 motorcycles
all with carbs to every car we and my kids have now.
Saturn, Nissan and Hondas.
IF, this is your prob and IF you have got it in time...
a good cleaner will work.
Ive run 2 tanks in my Civic Si when I got it before it cleared out.
This is IF you have a fuel prob.
How are your plugs?
