If you mean the 2.5 Liter Duratec, then your problem sounds like IACV mooseing. The Idle Air Control Valve (IACV) allows the engine to breathe even when the throttle body is fully closed, so that the engine doesn't stall while you aren't applying the gas. However, due to the way that Ford implemented crankcase gas return on the Duratec, debris and oil from partially combusted gasoline flows from the Exhaust Gas Return lines to the intake hose for the IACV and into the IACV. Over time these deposits can build up, disrupting movement of the valve, causing a moose like sound and a rough idle.
This is a very common problem with all Duratec engines, the vast majority of which will experience this issue. The cure is simple. Remove the IACV, disassemble it, and clean it thoroughly. Exact instructions on how to clean can be found in any car forum where Duratecs can be found, such as newcougar.org, or contour.org.
What else can I help you with?
What is the series of hollow tubes through which air flows to the intake ports?
Intake Manifold
Why does a 2002 KIA Spectra randomly stall when going from in gear to neutral?
One possiblilty would be the air intake hose, check the hose for any holes or leaks.
Where is the intake plenum?
The intake plenum on most cars is bolted directly atop the intake manifold. This is where the air goes after passing through the throttle body.
Can AIDS be passed through blood intake?
Yes it can.
Where does an intake manifold go on an engine?
The intake manifold attaches to the heads of the engine and send an air and fuel mixture to the combustion chamber through the intake valves. The intake manifold is usually situated on the top of the motor.
What is the role of the intake manifold in a motor?
The intake manifold in a motor is like the lungs of your car. Air is taken in through the intake manifold and then is evenly distributed to the cylinders to mix with gas.
Why do intake valves last longer than exhaust valves?
Intake valves are cooled by the gasses passing through them, exhaust valves are heated by the gasses passing through them and can be burned by overheating.
How many insects do we unknowingly consume in a year through our food intake?
On average, people unknowingly consume about 1-2 pounds of insects per year through their food intake.
What causes a motor to backfire out of the intake manifold?
A leaking spark plug wire can cause a backfire out of the intake, but the most common cause is a burned intake valve. A burnt intake valve will allow leakage during the compression stroke back through the intake causing a popping backfire out of the intake manifold.
What is the intake and exhaust valve purpous?
The fuel/air mixture passes through the intake valve to get into the combustion chamber. After combustion, the spent gasses travel out of the combustion chamber through the exhaust valve.
What direction does air flow through intake of 2012 Chevy traverse?
In the 2012 Chevy Traverse, air flows into the intake system from the outside environment through the air filter. The air then moves through the intake manifold and into the engine's combustion chambers, where it mixes with fuel for combustion. This process is essential for the engine to function properly and efficiently.
Where do you find the intake air temperature sensor on a 91 Honda civic?
The intake air temperature sensor on a 1991 Honda Civic is found on the intake. The intake air temperature reads to climate of the air that is being sucked in through to the engine.
