A worn or failing fuel injector causes real problems—rough idle, black smoke from the exhaust, poor fuel economy, and hard starting that leaves you stranded when work needs to get done. When injectors start getting clogged, worn, or developing leaks, you'll notice rough running, black smoke, poor fuel economy, or hard starting - problems that not only waste expensive diesel but can damage other engine components if you don't address them promptly. This replacement injector restores the precise fuel delivery your John Deere engine needs for clean combustion and full power.
