Ford Super Duty (1999-2016) :: 2005 F350 - Melted Air Intake Manifold Port - Code P0171 And P0174
Sep 5, 2015
Wife took truck out and turned around after going less then a mile, saying it was running very bad. We got this truck about two months ago at a state vehicle auction. It was a state used truck, 145,000 miles, 05 Ford F350, ext cab and 8' bed. Anyway at first I thought it was valve tap until research said an exhaust manifold. With a fog machine in rear exhaust pipe we confirmed it was leaking and replaced the exhaust manifold. Figured it was probably a good time to replace spark plugs too. Took truck for a ride and she still buck and farted.
Got a code machine and got P0171 and P0174. Couldn't find a vacuum leak, but your could hear the air being sucked in. went to local parts store, guys couldn't find leak, but they said truck sounded like a steam machine. today I made a homemade smoke machine and smoke came from air intake, figured the gaskets were bad. The pictures show what I saw when I took the gaskets off. The port that has melted is the same port were the exhaust manifold was leaking from. Am in deep "doo-doo". What caused this?

My 2005 f250 5.4 with codes p0171 and p0174. I have replaced fuel filter, MAF, Checked for vac leaks by smoke and water test.
I don't have a way to check fuel pressure on this thing since it must have been to much trouble to put that test port on the fuel rail!!!

Have a an 11 f350 6.2 gas throwing p0171 and 0174. Driving the truck it has spark knock pretty bad. Ive parked it at this point. Its a tow truck so I need it fixed and back on the road. I've checked the hoses going to the pcvs they appear to be ok.... Also upon starting the truck it just sounds weak.....

My 1999 F350 SD V10 that would crank but not start. I ended up checking numerous things because before it decided to truly stop running, it would run rough for a time and then be fine. The check Engine Light came on and I got the codes P0171 & P0174. Well, I bought MAF Cleaner and took the air cleaner housing off, disassembled it and thoroughly cleaned the sensor and replaced the air cleaner. I continued to get those same error codes, but before I could go any further, the truck totally died. It sat for nearly 2 months with the bed in the air as I had decided to lift the bed to check the fuel pump vs. drop the tank.
Fast forward a bit and I have since replaced the fuel pump and put $40 of Premium Gas along with Royal Purple Fuel Treatment in the tank because I figured things got stirred up and could use a bit of cleaning. I do not drive much, and during the first few trips, it ran perfectly. Then today, it started again with the rough running and trying to die if I let it idle. If I pushed on the gas, it would completely smooth out. If this were a carbureted engine, I would think the low idle was set too low, but since it is not, I am guessing it is one or more of the sensor/s that is/are causing the issue.
I am disabled and can’t play parts swap until I hit on the right part, so I was hoping that I might get some guidance here to narrow things down to the most probably causes so that I won’t go broke changing things until I hit the “right one”. The truck has 153,000 miles on it and I had bought it from a retired couple who used it to pull their 5th wheel travel trailer, so it had mostly highway miles on it. It was immaculate when I bought it and ran perfectly, needing only normal maintenance (oil changes, etc.) over the past 12 years that I have owned it. In those 12 years, I have put about 60,000 miles on it.

I've had DTC P0171 & P0174 (lean in bank 1 and lean in bank 2) for a few weeks now (check engine light cued me on it). Autozone scanned it for me. It's on a 2003 F250 SD 4x4 5.4L.
My first step was to clean the MAFS. Light came back on in about 30-40 miles. I then replaced the MAFS. 30-40 miles and the light came back on.
My first thought was disconnecting the battery wasn't resetting the comp and thats why the light was comming back on.
I went and picked up an Actron cheapy OBD II Scanner today at lunch. Cleared the codes with the scanner and drove back to work.
Checked the codes when I got back (no light on but was curious) and it shows P0171 & P0174 pending.
I've checked and the dipstick is seated properly. The hoses on the air intake appear to seated properly as well. The top hose is a pretty loose fit but it was seated all the way down. The top hose was oily. Not sure if this is normal or not. Could the loose fitting oily hose be the culprit?
Also, what is the lower hose? It comes off the back of the air intake and goes to the driver side valve cover. I know it's not the PCV hose as that is on the passenger side valve cover....right?

1999 F-250 LD 5.4... There is a hole on the back of the upper intake manifold, just below the back of the throttle body, is a vacuum hose supposed to be attached here? Have a serious vacuum leak, no coolant loss, no overheating, just had cop's and spark plugs done, now she backfires, stalls and will not stay running, mech. says its an intake gasket but the gasket and lower intake manifold look new.

I needed to replace the intake manifold gasket on my 2002 f250 v10. Tore everything apart put the new gasket in which was the same as the old one lyrics to notice something isn't right. I have been driving the truck for over 10 years like this. Is it OK to just continue bolting everything down and go on like this? I am guessing the prior owner 10 plus years ago put the wrong intake on. I keep looking up intakes but they all look just like the one I have. Also that port exposed is on the back passenger side.

I had a 05 f350 5.4 3v come into my shop with a CEL. Did the usual it had a p0307. So I did the usual again changed plug and coil plug cam out no prob they were done 15k ago. Test drove a few times and it was fine. Few days later customer brought back with same code p0307. thought maybe I got a bad plug or coil so I moved them to #6, misfire stays on #7. When I drive it local its fine when I go to pull on to highway and really put my foot in it CEL flashes (misfire) and it pings like crazy and loses all power. Scan it back at shop and still only p0307!!

2001 V10- F250.. Runs rough- had the computer put on it and was coming up with P0174 codes (I think that is right)- In any case I replaced the Mass air flow sensor- checked for any vacuum leaks visually- I did not see anything obvious.... still runs like crap.... smells like gas when idling.... anything else I can check??? The check engine light went off finally (probably due to the MAF)- but it's driving me nuts- Any hoses I have not located I need to check?

So I just bought a 2003 f250 v10 and I've plugged in my code reader and it couldn't get any info, so I took it to auto zone and they got an error code. I took a test lite to each little connection on the port with the ignition on and only got power to some of the metal connections on the port. So I'm wondering if all the little connections should have power? If so where should I start to look to find the problem?

2005 F350 crew cab with 6.0 currently cranks but no start with a P2291 error code. Using scanguage 2 it shows icp 0, IPR 67.7, FICM 47.5 while cranking. Disconnected ICP and still no start. removed icp and hooked up air and I do not hear/see any signs of air leaking. When I disconnect the air it then whooshes out. About 2 months ago got a #1 cylinder contribution error code and changed out that injector and it has ran fine up until this issue.
Can this be a IPR? I am leading towards the HPOP, but as it costs a pretty penny would really love to make sure I tried every other avenue.
I have 197K on it, and 2 years ago did a EGR cooler delete. In May this year replaced the oil cooler, and then in August changed out the #1 fuel injector.
Oil cooler screen was broken. Cleaned the entire reservoir out. Could this just be a clogged IPR? or seeing the change while cranking an indication that it is working?

2003 F350 short bed 6.8L V10---On start up a slight tap sound, almost like a cranky lifter, but it is an exhaust manifold leak. At the bolts, I am not sure. This has been this way for 5 years, no better no worse. After I run about 2 to 3 minutes it seals itself. Not a hint of noise. Due to heat, something is expanding to seal it (aluminum).
At my annual PA. State Safety Inspection the Tech says 'that has to be corrected if it worsens', but It does not fail inspection. This puzzles me.
How is the call made for correction. A flip of the coin, a guess and is it serious enough to fail inspection. Is this normal with the 6.8L or V10s. I know the cost involved for a fix is big league, but can it be justified. TRUCK RUNS GREAT !---

Bolts breaking on the exhaust manifold. If so why isn't ford doing a recall on this problem I have a F350 V10 90K miles and 3 on the top drivers side are missing not sure on the passenger side. Is this a problem with all the ford engines I have never had this problem with any other truck or car I have owned.

I just purchased a 2003 F250 Super Duty with the 6.8L V10 It has really high miles on it as it was a landscaping companies fleet truck. I'm sure that it was pretty well serviced as it has 300K miles on it and it's still running pretty decent.
I picked up the truck and I have to get the smog done soon. It idles with what I can only describe as a slight miss and it runs and drives great. seems to have plenty of power for the miles that's on it.
There is no active CEL on but I scanned the OBDII system and found a P0171 Lean bank 1 code in the pending codes list of the scanner. I guess this year engine doesn't have an EGR Valve or DPFE sensor because I've looked high and low for it and there non existent on this engine.
I've checked for vacuum leaks by spraying brake cleaner or carb cleaner all over the place and it makes no difference and all the vacuum lines and connections look okay.
When it's running It does sound like a vacuum leak right behind the top of the plastic throttle body but I can't find it, I don't know if this big *** engine just sucks that much air or what.
Like I said I need to smog this thing soon and I don't want it to fail if it's missing or has another issue. The fuel injectors look new and one coil pack looks like it's a replacement...

2002 F-250 5.4l 4x4 ... I am getting a P0171 code only, with strong fuel smell. No P0174 code. So it has to be something effecting just the one bank? Sprayed engine with starting fluid, no charge in idle. Replaced upstream O2 sensor, no change. Truck was running fine, and then just started this all at once.

I 'm looking to replace my manifold studs in my 2005 V10. Looking to replace with bolts. Would like someone who has done this to chime in with what they have had success using for bolts. Size length grade etc.

I have a 2005 f250 5.4 no mods. its got 120k and needs a wake up. the passengers side exhaust manifold is leaking to the point of fixing and would like to get some input before the big purchase. my question is, headers or new manifold, and what brands is preferred for both I really don't prefer one or the other i just want the best fix really. Changing coil pack and getting more performance out of them and if so what brand. I would like a boost in lower end acceleration and throttle response, like a programmer or such. and if so what brand once again.

I have a 2011 F350 CC long box 4x4, with a 6.2, 93,000 km on it. I periodically get a P0420. I clear it and sometimes it comes back in 10 or 20 KM and sometimes it comes back in a couple hundred km. Been doing this for about 800 KM.
Yesterday I got an exaust leak at the joint where the exaust manifold meets the pipe beside the engine. Checked close, bolts appear intact, leak is on the outboard side blowing towards the frame. Looks like a gasket or donut seal failed.
I am wondering if the catalytic converter was plugged or restrictive, would this cause the P0420 and could back pressure from a restricted catalyitic converter cause the gasket to blow?

I have and 05 F350 4X4. I put it into 4 wheel drive high yesterday to make sure every thing was working correctly and it was so I went to 4 wheel low and that worked fine. Problem is it won't come out of 4 wheel low. I didn't try to go back to 2 wheel when I was in 4 high. What to look for? The truck has the electric switch to engage 4 wheel.

Recently drove a 3500 mile road trip with no issues after installing a SCT X4 programmer from 5 star. Upon returning home the following week the ABS light came on and has not gone off. Additionally, last week the truck stalled while driving down the road at around 45 mph. Had something similar happen last summer, got the truck stuck and was trying to rock it in the mud and every time I shifted from reverse or forward the rpm's dropped to 500 and the truck could not respond to the gas pedal and the ABS light came on. Once I got out and washed all the mud from under it light went off and it ran fine without any warning lights.
Truck is an 05, V-10, 4x4, off road and tow package, lariat. No other mods besides the programmer.

My dad gave his 2005 Ford F-350 truck with the gas 5.4L (?) I drove it home. If i floor it it misfires badly, or if the RPM's get over 3000 it misfires then about 3800 it stops and keeps going. but i can't give it to much gas....
The spark plugs where replaced 2 years ago along with the cat converters. I can hear some very fait manifold gasket leak ...
A few days ago it was raining and it had a bad misfire with blinking CEL. but it never threw a solid CLE. can i still put the codes on it to see what cylinder it is? Are these issue related? Where should i start?
