Your Chrysler fuel injectors will most likely suffer from failure when the nozzles become clogged with residue left over from your engine operations. That accumulation of deposits eventually leads to a lean air-fuel mixture in the combustion cycle, which causes engine detonations, knocking, loss of power and a drop in your gas mileage. The residue is mostly deposits left over from the gasoline, which is a mixture of many different hydrocarbons. Some of those hydrocarbons include oilfins, which are heavy, waxy compounds that are prone to coat the inside of the fuel system. When the engine is shut off, the fuel residue in the injector nozzles evaporates, leaving the waxy oilfins behind. At that point, because the engine is not working, there is no cooling air flow through the ports and no fuel flow through the injectors to wash away those deposits. Heat bakes the oilfin into hard varnish deposits. Over time, these deposits can build up and clog the injectors. These deposits are part of the normal operations of an engine, so detergents are added to gasoline to help keep the injectors clean. However, those detergents can only work so far, especially for cars that driven mostly for short distances. These deposits tend to affect older models the most; they will collect in the combustion chamber, fuel injectors, valves and other parts of the fuel system. If you suspect that your Chrysler fuel injectors are irreparably clogged, then order replacements here and install them yourself!
