1. Leaking injector nozzles - If there is a problem with the o-ring that fits on the injector, replacing the ring will usually fix the leak. If the injector body, nozzle, or internal components are cracked, a new or refurbished injector is your only option.
2. Replacement injector seals and gaskets are inexpensive and fairly easy to install. This usually does the trick, and it's not too hard to do if you're good with a wrench.
3. Dirty injector nozzles - It's fairly cheap to have your car's injectors cleaned and serviced by a professional. This involves inspection and cleaning of the injectors, usually with a pressure washer. If the injector is in good working order and passes the ohms test, replace the seals and o-rings before reinstalling.
4. It is recommended that you clean them regularly to prevent problems.
5. It is also a good idea to run a fuel system cleaner on your car a few times a year. This will help keep the injectors, fuel pump and fuel lines clean and free of carbon deposits. It will also increase injector service intervals.
6. Clogged injector nozzles - Clogged injectors can usually be repaired if you can spot the problem quickly. Sometimes, due to years of neglect or lack of regular engine maintenance, the injectors become completely clogged. If this is the case, then a retrofit replacement may be the only option. Likewise, regular use of a fuel system cleaner can help prevent injector clogging in the first place.
