Not enough fuel to them. Most l;likely a fuel pressure regulator problem
timing belt, spark plugs, wires, fuel/air mix, fuel injectors
Black smoke is : too much fuel and not enough air, a faulty injector (s). Take out the injectors and have them tested before you do engine damage.
Yes. Fuel injectors that are worn out can "slobber" fuel into the engine creating a rich mixture. This means to much fuel, not enough air = poor fuel economy. This can also be caused by a very dirty air cleaner, bad Oxy sensor(s), bad mass air flow sensor, carboned IAC valve and a host of other things.
No, it has fuel injectors and a plenum to move air to the cylinder. It has no carburetor.
There can be many items but some are: Spark Plugs & wires Fuel Filter Fuel Pump Injectors Temp Sensors Clogged Air Filter What to check first is the filers.
the fuel injectors are located on the top of the throttle body, to get at them take off the air filter assembly, once you remove that you will see the two injectors on the top.
Fuel Injectors rail driver side, same look as the fitting to put air on your trucks tire.................Fuel rail is the tubing that supplies fuel to the fuel injectors..
If the injectors are spraying more fuel with out anything else changing, then yes, the plugs will foul. To get more power you need more air in the engine as much as you need more fuel.
There are numerous issues that can cause a lack of power during acceleration. Common causes include a clogged fuel filter, a clogged air filter, and dirty fuel injectors.
It usually means too much fuel or not enough spark.
Look on top of the engine at the inlet side of the fuel line from the fuel tanj and you will fine a Fuel Pressure Regulator. have it checked. It sound like it is stuck open. It is suppose to open and close to regulate the proper pressure to each of the fuel injectors.
The main difference between port fuel injectors and direct injection injectors lies in where the fuel is delivered in the engine. Port fuel injectors spray fuel into the intake manifold, mixing it with air before it enters the combustion chamber. In contrast, direct injection injectors inject fuel directly into the combustion chamber at high pressure, allowing for more precise fuel metering and better combustion efficiency. This difference can significantly affect engine performance, emissions, and fuel economy.
