This unmetered air entering the engine is usually due to a very large vacuum leak. The list of automotive Makes at the right edge of the screen.

Enter the 5 character trouble codes in the search box and submit the search. Need help with a P0174 code? This is done most easily from below the car in the area near the oil filter. They leak vacuum and cause rough idling and in more extreme cases stalling. It consist of air filter, ducts, air plenum and intake manifold. If your computer has triggered a trouble code for a possible failed oxygen sensor along with other codes, check those other codes first. This bank is the one on the passenger side of the engine see the illustration in the image viewer.
What causes the P0174 code? My undestanding was not unklie yours, I thought it had all the codes on it and the light would come on when it reconised the code was interupted? But it's true that oxygen sensors can also fail. A carburetor cleaner can help see any potential leaks by simply spraying it around the surface of the gasket. Fuel trims are settings which control the amount of fuel entering the engine to achieve a stoichiometric ratio of 14. Although you can apply this info to any Ford vehicle with a V6 or V8, this info concentrates on the Ford 4. Except the first three , those are genaric codes , same for all makes! Basically this means that an oxygen sensor in bank 2 detected a lean condition too much oxygen in the exhaust. During the tests, wrap a rag around any fuel hose you need to pinch with the pliers. It's a very common problem for the Ford Windstar.
Vacuum leak faults usually—not always—manifest more readily at lower speeds; as a rough idle, for example. Surging, delayed acceleration, rough idle, stalling, and a general feeling of misfire when accelerating. More importantly, I'll offer you a diagnostic strategy that will help you to troubleshoot the issue. There are three types of clutch systems: mechanical, cable and hydraulic.

If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes.

At full throttle, a small leak will contribute far less air to the large overall volume of air entering the engine. A loose or damaged boot can introduce unmetered air.
Intake Manifold Gasket Leaking If the engine is a V8 or V6 and only one side or bank is reporting a fault code it could be a leaking intake manifold gasket or leaking manifold. If O2 sensors are causing both P0171 and P0174 banks to report a lean mixture, that would mean that both O2 sensors are misreading the amount of oxygen in the exhaust. When the car computer detects a lean condition in the O2 sensor, it will immediately try to correct the lean condition and return to the stoichiometric ratio by adding fuel. Most the time it's a vacuum leak. If you don't have the manual for your model, you can buy a relatively inexpensive aftermarket manual from Amazon.
