Definitely check the foam on the air filter box. I have a 2005 expedition 5.4 that wasn't pulling any codes (at least not to the point of tripping the check engine light), but I was getting atrocious gas mileage, as well as a drastic issue with power at times. When I would floor it, I would get almost bursts of power between bogged down acceleration. I also had the obnoxious diesel sound once warm at idle. I found that issue, cleaned off all old foam, and replaced with new padding. It solved all my issues, including (somehow) quieting down the engine.

@xcataclysmx I don't know if the man here himself knows or has ran into this... After days and days There is a very big difference in those spark plug numbers. I will say I discovered and I will also say that in the back of the intake where it meets the heads. We're leaking ever, so slightly. You could not notice a misfire, didn't really have any symptoms that you would think? Nothing like the brake cleaner trick. Nothing like that would work. Nothing made sense. Put a smoke machine on it. Nothing and then I got the idea well. Let's pressurize the smoke a little bit and then the smoke started rolling out of the back of the intake gaskets on both sides. It was slightly leaking and that was causing so many problems

I went through H*LL trying to fix my lean codes on my 2005 3V 5.4L F-150...Isolated every vacuum line, pulled the manifold to check for cracks, replaced MAF, replaced fuel pump and then Fuel Pressure Sensor. Went to 2 Ford dealerships and a diagnostic shop. Last shop says everything checks out and I had to think outside the box. They even replaced the computer at no charge when it didn't fix the problem.. I had a scanner that showed the fuel trims and knew they were off. Also took into account the problems with the 05 injectors. I went one size up and replaced ALL the injectors. That solved the problem. Trims went to the Rich side but within spec. Hope I'm not just masking a problem. Been 2 years, no problem

Perfect Video and Perfect Timing! Bruddah as always - You and Your Videos Rock !! Got a couple important questions for you. 1. How reliable are the "Re-man'd sensors"? And... 2. What companies would you recommend if we can't buy from OEM? 3. Which companies have you steered away from? I have yet to hear any good things about Dorman electronics and of course their "exact fit parts" are already #1 on the Top 10 Don't Buy charts - unless you really, really have too. Even then -- "Buyer Beware". The wife's 2007 toyota Camry has been giving us issues lately. Her XLT Camry was bought new in summer of 2007 and has been a trouble free car from day one. Now at over 100,000 miles it's asking for some normal and expected detailed, in-depth and attentive TLC. And she'll get it. Great Car. Last week I was getting the same codes you spoke of in the video wrt the fuel trims and DTC's. Wife came home from work saying the "Check Engine is On". Using your past videos as a guide and my scan tool combined with my very limited skill sets - I was able to fix all of the issues by simply cleaning the MAF, the throttle plate and the K&N flat air filter. Bruddah - I can say this - All is well in the islands. Happy Wife - Happy life and it's real time proof to the wife that (pounding my chest like Hercules) "Man needs to buy more tools!!" -- "Honey, buying that $400 scan tool just saved us a lot of money" and "this tool just paid for itself!" (cough - cough - ah - emm, honest it does ;)) Once Again Your Videos let me fix it right and saved us a boatload of money by not having to spend on things I didn't need to buy. Not to mention that I am able to better Interpret, Understand, and Utilize my scan tool. I was really worried that I'd have to buy a new MAF and/or TBS. That would of easily cost me over $500. Toyota over here wants $198 for the MAF and a new Throttle Body (sensor included) is over $300. The TPS sensor isn't sold separately over here. I went to a friend who works at a Toyota dealership in the parts department and said the same thing "sorry bruddah - You have to buy the whole Throttle Body assembly". They said it's because of the TPS and Body design. I Say - I smell a wolf in the hen house as I cough "Rip Off" out loud. Any Howz -- Thanks Again Bruddah!!

I have the same year truck with the same motor. Today when leaving the hardware store it started making a strange intermittent clunking noise coming from either the engine or the front wheel area. I thought for sure it was something serious with the engine. The check engine light came on and code 174 and 171 were discovered later. I decided to try to drive it home 6 miles on the highway. Once I got up past 25 miles an hour there was no more clunking and the engine seemed to run fine. As soon as I got near my house and reduced speed to around 20 miles an hour the clunking resumed. It almost sounded like the four-wheel drive was attempting to engage. I got it to the garage and clean the mass air flow sensor and took it for a test drive. The clunking remained present at low speeds. When I purchased the truck which has 220,000 miles on it there was a check engine light on but after changing the oil and adding some Lucas it went away. The previous owner thought the vehicle jumped time but it ran fine for me although the codes at the time did seem to indicate an issue with the cam phasers or the timing chain. I'm wondering if the timing chain or the slack adjusters have finally worn too far? Oddly however at highway speeds it ran fine. It wasn't just a rough idle at lower speeds it was definitely clunking intermittently. I'm going to further check the vacuum lines but it sounds mechanical. Any advice?

Here is one more oddity to add to the diagnosis. After spending hours checking for vacuum leaks including smoke testing the entire system my mechanic could not find a leak. So he decided to check the fuel pressure and discovered it was barely in the acceptable range. This is on a 2002 F150 Harley Davidson Edition with 98K miles. So, the codes were being dropped for a low fuel condition that would look just like too much air to the computer. Weird right? He said he had only seen this two other times. Once on his F150 Lightning and once on another standard F150 with 5.4L. Solution was to replace the in-tank dual fuel pumps and all the accessories. Way to go Jason!

Your videos are really outstanding. i never paid any attention to the bottom of the air filter as you described in your video so I inspected mine. Guess what mine was all falling apart as you have shown in the video so I order the tray seal. Upon receiving the seal the exact measurement of the seal width is 1 1/4 inches and the old foam was 1 inch so it had to be trimmed off to the exact width as needed. However the seal really sticks onto the housing just wanted to give a heads up so others will know what to expect. Although I don't have any error codes yet just trying to eliminate them before they occur. I am a firm believer of preventive maintenance. Can you tell us what the part numbers for the two hoses you described in your video in reference to the vapor feed hose and the brake booster hose to the bottom of the intake. I would like to replace both of them now before I have a problem. Many thanks, IMHO your the best videos out there.

Thank you so much for your video. My 04 expedition has these codes, and now I know what to look for. You have saved me thousands of dollars. Keep up the good work.

Me here bc I'm once again chasing 2v lean codes 😭 Engine pushing 200k (not bad for an 03) and fuel economy down to the 8-9s on top of the lean codes 🥲

Any idea where to find that vapor line for the purge canister honestly can't find anywhere and mines in bad shape.

Have you ever covered oil dipstick tube replacement on a 5.4 in a Superduty? Mine has broken off at the pan.

I just did one on a 2003 F150 5.4. Was not a fun job. I had to unbolt the exhaust manifold from the block to get enough clearance to snake the new one in.

My dad has a 99 F150 and is fighting this issue. Ford replaced the PCV tube, code came back then they told him he has low compression on entire second back, then they said it is a timing issue, $1000 to check and reset if needed or if it is worn $3000 to replace. He could spend his entire retirement chasing this issue...

Would have been cool to see the test drive with the new MAF sensor. That way we could see the fuel trims at higher RPM's. Great video regardless. Very informative and helpful. Checked my filter door seal and it was completely gone. Giant gap for air to enter housing. Seams like the filter seal would stop that from vortexing the MAF sensor area, but I trust your expertise over mine. I think I will try duck tape first, if that works I'll be looking for that air filter door seal. If you know where to get one, let me know. The vortex in the air filter housing was good info. Are there other seals on that housing I should check? Can't tell unless I take it all apart. Didn't want to fix what isn't broken, even though I do that sometimes anyways. Great info, thanks for the tip lesson.

Any thing different for the two valve ? I have a 2001 and have had trouble with both lean bank codes and recently experienced a rough idol and rpms bouncing and occasionally wants to die at a stop

I keep getting lean codes on my 2006 F150 5.4L on mainly bank 1 but sometimes on bank 2. I have smoke tested Vacuum system and no leaks found. LTFT bank 1 idling is around 15% . exhaust smells rich to me also received O2s11 code once but hasn't came back. truck will intermittently mis and loose power on highway. Just not sure if I should replace 02 sensors again as I changed them all about 15k miles ago.

Where can you buy the brake booster / intake manifold vacume conector you dhiw in this video!!

@jonrandall5490 3 жыл бұрын

SUPERB !! I enjoyed this video, even tho some of this is over my head ( reading live data, etc... ). I have heard that the difficult rear booster line firewall / bottom of the intake manifold leak can be accessed via taking the drivers side wheel off and reaching in thru that way? Do you know anything about this, Dr. Ford Guru ? Mine is a 2005 F-150 with 5.4L 2wd. Thanks. Excellent video by someone who knows what he is doing !!

Can’t believe I’m asking this……where/how do you find replace vacuum lines/tubes for 5.4L 3v? Would think it would be easy to find kit(s), but unless you do this by simply buying off the shelf emission hose at any parts store, I can’t find what should be any easy find. Pardon my being so brain dead, but much appreciated if any help…..
