What was the reason why you took the intake manifold out?

Hi, from your experience, what can cause the engine to shake only after warming up? The shaking seems to always start after I hear a noise, similar to the sound hot metal would make if water was poured on it, or many like a little metal hamar hitting a metal bell. Then next time, after it cools down, it doesn't shake until it warms up again. Steam is coming out of the exhaust pipe, I thought it was a leaking head gasket but I tried a few of the best head gasket sealers and it didn't seem to help. Do you think maybe the upper intake is leaking coolant into the combustion chamber? Maybe a bad valve? I really appreciate you sharing your experience with us.

Very good info thanks dude

Took off way too much. battery cable, alternator, throttle body, vacuum sensor with the 2 (#8 head) bolts fuel line, (not the rail) 8 (#10 head) bolts of the intake. Carefully lift intake slide forward so you can fish your hand under it to the back to unplug 2 knock sensors, the imrc control and a vacuum line at the bottom rear of air box. Watch the wires they may be wrapped around the arms of the imrc.

Gracias por el video

Removing your gas cap has zero effect on line pressure in your rail. Whoever told you that knows nothing about it.

Do you have a diagram of where all those vacuum lines go? I did an engine swap and forgot where all the lines go

Ball of wax

Are the flaps supposed to be closed or open upon removal of intake

Thanks for the removal video Tips on putting it back? The vacuum port on the rear bottom left is the one giving me the most trouble on my '07 Expedition.

I didn't drain coolent on the one I'm working on. Moved the alternator forward and had enough room to pull it out.

How do u get 8mm nut off back?

Did you have a cylinder 5 misfire or did check engine light flash when it was acting up?

Nice video - only - don’t you have to put sensor wires **over the metal bars not under, or they get pinched and do not perform their function.

I have a 04 and have the same issues got the sensor replaced but it still throws the same code

Is it the same location for 2007 lincoln navigator?

Doing this now helpful video thank you

Thank you, helped a lot. 07 expedition , the wire retaining nuts at the back , is size 10mm.

Good job , is an excelente explanation. Thanks for this video. I need to do this work in my car.

Thanks for the info

Your video was helpful. Thanks The shop has put 3 Dorman intakes on my 05 F250. They last 6 months or so and then it is P1071 and P1074 lean condition. Have confirmed it is vacuum leak w homemade smoke tester. I got a used ford manifold and it looks way better. got the used one because I needed factory hardware for the intake runner that Ford no longer sells and the Dorman hardware is different. Had to remove and reinstall the runner blades so I could give the intake a good cleaning. Waiting on parts to come in. I bet dealing w those connectors under the manifold that you can not see are going to be the most fun.

I replaced that sensor on my Expedition 5.4 with out removing the intake.Not easy but doable.

Here is my terrible attempt at explaining the wiring harness and vacuum hose on the back of the manifold. May the Auto Gods be with you while you tumble down this terrible rabbit hole... kzbin.info/www/bejne/e4HNgoh-mLitq8k&lc=UgyHtpYJZoIvTw3qg4d4AaABAg

What is the plug for on the back of intake ?

Thank you for sharing, looking at same issue

You mention the cylinder head temp sensor wire harness. does this harness unplug on both ends? You tap a black female plug in the video, the plug end on my CHT is white, so is this just a short pigtail that can be replaced? I'm having the exact issue with my truck, and was wondering if I could replace that wire without removing the intake manifold. I believe if it plugs on each end that I can. Thanks for your time.

OMG pure chaos, no sequence

Have the Same code. Replaced my sensor with one from O'Reillys and is still running bad. Did you use a Ford part or aftermarket?
