Jeep Grand Cherokee Fuel Injectors
Beginning in the 1980s, car manufacturers started to replace carburetors with fuel injection systems in order to improve on things such as efficiency, emissions performance, power output, and reliability. With an injection system, fuel is atomized under high pressure through a small nozzle as it is delivered into the combustion chamber.What are some signs of a bad fuel injector?
When you start noticing small performance anomalies with your Cherokee, it can be easy to ignore them at first, figuring it might not be too serious. The problem is that mechanical issues have a way of creeping up on vehicle owners. Jeep Cherokee fuel injector problems might very well start out the same way. Its important to look into it as soon as they are detected so that you avoid more serious mechanical issues down the road. Here is a quick look at things to keep an eye out for:
- Inconsistent or lack of power: This problem can be caused by a number of reasons and a dirty fuel injector could be one of them. This happens because additives in the gasoline dont get sprayed into the intake manifold but rather end up becoming a residue on the injectors. Since they operate in intense heat, these additives burn and turn into a crust like substance that in turn causes a weak and uneven spray pattern.
- Clogged fuel injectors: Moisture has a way of invading a vehicles fuel system, especially if it has sat idle for some time. This causes rust to form around the fuel injectors, which clogs them up and prevents the gasoline from exiting the nozzle.
The fuel rail, also known as the fuel pressure sensor, is a part of the engine management system. Though designed primarily for diesel ran automobiles and trucks, there are some gasoline-fueled vehicles that also use this system, such as the Jeep Cherokee. Here are some symptoms youll notice when its time to replace the fuel rail:
- Black soot on the spark plugs
- Black smoke coming from the exhaust
- Gasoline drips from the exhaust
- Dipstick for measuring the oil smells like gasoline
- Vacuum hose for fuel pressure regulator has gasoline in it
There are a number of Jeep Cherokee models out there and not all of them share the same parts. This is why its a good idea to get your owners manual and find information such as production year, exact model, and engine size. With this information, you should be able to locate the correct fuel injector for your vehicle.
