Hi,
I have a 2002 Altima that just had it's 60,000 mile service.
The mechanic recommended cleaning the fuel injectors as preventive
maintenance since Nissans have, in his words, "notorious problems with
injectors getting dirty leading to costly repairs."
I held off on it since I didn't feel like spending the extra $148 that was
his fee "MotorVac" injector cleaning until I had a chance to look into this
a bit.
I'm looking for opinions on if I should go ahead and have this done soon.
thanks,
Tom

Yes, go ahead and have it done, except for bringing it back to the shop.
Buy a can of injector cleaner and dump it in the gas tank. I went to
50,000 miles before I did it and although I didn't have any problems
before 50k, I didn't have any after either.

Knocking on wood, my 94 Maxima never had any issues with fuel injectors,
and I never used any cleaners.

i occasionally buy a bottle of complete system cleaner and dump it in
my full tank. My 91 runs perfect even with 223,000 miles, gotta love
the 1.6

Get a new mechanic because yours is either a hack (it's common for
hacks to suggest injector cleaning and tune-ups as cure alls) , or a
crook who wants to pay off his Motorvac machine. Injectors made that
recently don't clog nearly as much as those from the 1980s or even
early 1990s, and gasoline has better additive packages than it used to,
thanks to EPA and auto maker requirements. Injector flushing can
actually cause damage by dissolving insulation from the gasoline-cooled
solonoid coils, so it shouldn't be done unless the injectors are known
to be clogged and suspected to be in need of replacement anyway. Just
use a bottle of Techron about every 10,000 - 15,000 miles. It'll not
only keep injectors clean -- safely, but also remove carbon from intake
valves and combustion chambers. It's also sold as Chevron Pro Guard
Clean Up, not to be confused with Stay Clean or Fuel Injector Cleaner,
which are more dilute.
