What are the symptoms of needing an injector flush?
Injectors are basically self cleaning and actual instances of needing additional cleaning are relatively rare. The most common symptom is a rough idle. When an injector tip gets dirty, the spray pattern becomes more of a dribble than a spray. At very low speed, like idle, this can disturb air/fuel mixture. At higher speeds the effect will be less. A dirty injector will rarely cause a misfire at speed. A failed injector is another matter. When injectors fail, they can stay closed, open or partially open. This can cause a misfire, check engine light and other problems. Failed injectors require replacement, flushing will not help. For more information on services that are over sold, please see our Detailed Topics Section, for the article, Wallet Flushes.
