Diagnostic trouble codes, including P0300-P0308 or DTC P050D, will be set.
Other symptoms of a bad or dirty fuel injector include: The vehicle is hard to start and idles rough; Poor performance and increased fuel consumption; and an engine knock or detonation that could lead to complete engine failure.
