Regular oil and filter changes will go a long way towards maintaining a healthy engine. Over time, these will eventually block the injector. Such damage can cause fuel to be wasted by leaking from the body or by supplying excessive fuel when the internal springs are damaged. It will also increase the service intervals of the injectors. Leaking fuel injectors can cause Oil Thinning. Dirt and rust contamination is the #2 cause of fuel pump failure. I am having a misfire only on wide open throttle.

Gasoline of unreliable quality, destructive driving circumstances (such as stop-and-go traffic) and your car's overall condition can add up, causing premature fuel injector failure. The misfire will easily be felt while driving, and often requires immediate repair by trained automotive repair specialists. This not only gives vehicles better gas mileage; but it also cuts down on the pollution that they emit in comparison to older technologies. Again, regular use of a fuel system cleaner can help to prevent clogged injectors. This causes any fuel left in the injector to evaporate; leaving behind hard deposits inside the injector. When functioning properly, you can have great fuel economy, high engine power, and a smooth ride. Fuel injectors make a sharp clicking sound when they are functioning properly; so the absence of this sound can indicate a problem with an injector. When something goes wrong with this sophisticated technology; it can feel intimidating for many car owners; leading them to often take their vehicles for a professional diagnosis. So, The most effective way to keep injectors in good working order is; to have them removed and inspected at regular intervals.
