Ford Focus 2.0 intake manifold swirl flaps code P2004

This 2005 Ford Focus has over 180,000 miles on it but it's time for a intake manifold repair. The plastic parts wear down over time and eventually break apart, falling into your intake valves. If your Focus has over 150,000 miles on it, its a good idea to inspect the flap assemblies. The PCV valve is also a periodic maintenance part which should be replaced while the intake manifold is removed.
Thanks for watching!

Kool video, I am taking the Intake manifold off my focus now, to delete control solenoids.

[@akaitv6606]

Excellent video

[@chrisl2090]

taking my intake off very soon and i'm taking those swirl flaps out.. Read from alot of people on forums the risk doesnt outway the benefits of those swirl flaps. People have had those break and go straight into the intake valves causing catastrophic failures.. Just realized you said this.. But Just clarifying that I am just going to completely remove them.

[@christiangibson5948]

How did that work for you ???

[@chrisl2090]

@@christiangibson5948 well as it would be someone ran a stop sign hit my car and totaled it. so for the 4 months that I did have them off it worked fine. No more rattle. Gas mileage went down though. Mostly intown that it was effected

Thank you super helpful

[@Demon09-_-]

man I hate theses plastic intake manifolds. every new car I see has these dang tumbler or swirl flap's let's go back to aluminum intake manifolds I'd Glady pay a few bucks more to not have to worry about a swirl flap's breaking and killing my engine

Thank you

I have an 08 focus, same code came up would it be the same issue, 190k miles

[@fredroe7556]

Any idea where I can get that white lever that hooks to acuator???

[@Jacob1986]

I have p2004 code i tested my actuator it works perfect and i dont see any resistance . My mechanic recommended seafoam. I did that the code went away for a week. It went off before on its own without seafoam. Code came back yesterday. Im guessing the switch is cruded over. Anyway to clean it? Or do I need to run seafoam again?

[@collineastman8076]

In my opinion seafoam does not change anything on our duratec 2.0l engine because the port injection cleans the valves. The manifold gets gummed up by oil from the PCV valve but seafoam won't clean that because it accumulates at the bottom of the manifold. The problem is likely the worn flaps that are getting jammed intermittently.

[@bluesummersky6936]

Can a p0171 be caused also by the swirl flaps? I had a broken pcv hose, and i fixed it and the code went away for a while. While i changed that pcv hose, i noticed that the swirl flaps are quite worn so that's why im wondering whether those could cause that code as well... because if they rattle inside they might let too much air inside and it messes with fuel trims, and after a while after I clear the code, it apppears (1 week..)

That's running lean, same issue for mine

[@bluesummersky6936]

@@roberthaselhurst6863 how did you solve it? I changed the swirl flaps but it didn't solve the problem

[@roberthaselhurst6863]

@@bluesummersky6936 I basically changed the top 02 sensor, but it was a air/fuel wide band sensor, not a generic 02 sensor, it still does come up every couple thousand miles but I think that's because it's got no swirl flaps

[@roberthaselhurst6863]

And Also I think it might be due to the current stock map thinking its still got the swirl flaps in the intake at idle

[@bluesummersky6936]

@@roberthaselhurst6863 hmm probably, I wanted to eliminate the cause of swirl flaps that's why I wanted to change the intake manifold

[@55chevytruck]

I have the dreaded po171 code. Hoses look good so i swaped in a new MAS sensor and seemed to do the trick then the idle got rough but runs good at higher rpms and now po272 is back. took intake off to do PVC valve and my flaps looked good but there is oil around them and in takes. Any ideas would be nice. thanks for posting.

[@collineastman8076]

Hello, is the "rough idle" you are describing sort of a surging sound and it almost seems like the engine is trying to idle normally but keeps getting bogged down in waves? If so, the pcv valve could be clogged with sludge/oil which would stop the crankcase from expelling the crankcase vapor into the manifold. Although p0171 can be caused by several factors, it is worth removing the pcv valve and making sure it is not clogged(it is a simple/cheap 1 way valve that should rattle when you shake it)

[@55chevytruck]

Where is this pull a part at? I'm in California, car sounds a little like a diesel, thought it was a valve then I got the P2004 code. thanks

[@collineastman8076]

pull a part is just a large chain of scrapyards in the east of the U.S. any scrapyard with cars(specifically the focus with the duratec 2.0) will have the part your looking for. the ford escape and mazda 3 also use the duratec 2.0 engine and will have the same intake manifold too. just make sure EVERYTHING on the used manifold is in working order.

[@andrewmoreno2877]

will that cause the engine sound like a diesel?

[@collineastman8076]

Yes in a way it sounds like the clicking of diesel injectors. This is a very common problem with the Duratec 2.0 engines and it is often mistaken for injector chatter. Although injectors do make a small clicking noise, if the noise is louder than it has been previously, it is likely the manifold's flaps deteriorating.

[@collineastman8076]

Also there is a easy test that may provide information on your issue. First look at the manifold when it is on the engine and locate the throttle body(There is a rubber tube/boot leading up to the throttle body). Look from above at the throttle body and locate the ONLY white piece of plastic next to it(it is small and has a rounded black arm connected to it which is the actuator i show in the video). While the engine is running, push that white piece down and listen for any change in the clicking noise. If the noise changes or goes away it is definitely the flaps.

[@simonjohnhinton1938]

I did mine on my 2.0 its a 2005 Ghia x with 145,000 miles. When I inspected them they were OK but I changed then for new ones nevertheless. A set of 4 cost me £64 and the 4 gaskets and o ring were another £24. I did toy with the idea of removing them altogether and filling the holes with Araldite and then once dry sanding them over but for continuity's sake I bought new ones. Duratec is a good engine and mine averages 35.3mpg. If I want more economy I'll go the LPG route rather than buy a diesel version of the mk3. The mk4 diesels are more refined but use a cambelt rather than camchain.

[@baietze1u]

Do you still have the FINIS code (or part number) for those swirl flaps? I couldn't find this code anywhere. I must chance at least two of them.

[@RELLIKPIR]

Keep having Europe people being able to find these but no one in america can for some reason. Ford does not have a part number that they will tell me about.

[@jamewakk]

When i started to get that sound from my engine i just took of the manifold and deleted the swirl flaps.

[@eddiethegiantgaming8591]

How does it run

[@jamewakk]

[@erezlevy6619]

Did it cause a check engine light?

[@MasterChief-sl9ro]

You can use epoxy to fix that shit. If you can't find a used one...

[@collineastman8076]

That would require some serious precision but i guess it's feasible if the epoxy doesn't restrict the rotation of the flaps. Some people just remove them and plug the hole so theres no vacuum leaks. Although the flaps are there for improved efficiency at low rpms.

[@MasterChief-sl9ro]

Just use brass bushing. Epoxy them in. As the issue is the rod bearing wearing out. Then falls into your engine. You can also reverse the rod. Then buy new flappers and rebuild it for way less. Then a new intake.
