Is it ever really needed?
Dealers are always trying to sell the $159 fuel injection service and
recommend it every 15,000 miles. Seems kind of steep to do that
often. The service consists of a $75 parts kit and the rest labor.
Having driven hundreds of thousands of miles and never an injection
problem, I'm hesitant, but there may be a point that it is a good
idea. I do know that people have had injector problems, but I'm not
sure just how often it comes up.
