Ford Super Duty (1999-2016) :: Back Firing Through Intake Then Engine Dies
Mar 3, 2015
The truck starts up fine. then after a minute or so it starts to spit and sputter and back fire through the intake then dies.
What could cause this? Intake manifold gasket leak?
Will a clogged fuel filter cause this?
5.4 ....

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 have a leak where my heater core tube goes into the intake at the rear pass side of engine. I have read that this part is pressed in. I dont want to remove the intake since i just paid $400 to have a new gasket kit put on. My question is can I bypass this tube with a hose from the water pump like in this video?
FORD 4.6 , 5.4 , 6.8, HEATER HOSE UNDER INTAKE REPLACEMENT THE EASY WAY !!! - YouTube....
If I can do a rubber hose like in the video I was to make sure that the tube just goes through the intake and that it does not supple coolant into the intake??

Our 7.3 won't fire. After a few weeks of thinking we had glow plug issues on firing we feel we may have another issue instead.
In cold morning of past say -1 to -7 we have had a lot of trouble firing the old girl, we would preheat 3 or 4 times and it would wind over and over. Stop repreheat and try again and it would turn over quicker. Preheat again and it would fire.
We have a diesel leak as well and was thinking that the pressure maybe low because of it. It is now with the mechanic and he can't find the diesel leak but it pools on top of the engine and drains down the back of the motor over the belt housing.
He cleaned it all up and checked the ICP sensor and it was full of oil, he cleaned it and refuted it and it fired. He then ran it for around half an hour to see if he could spot the fuel leak, he turned it off and now it will not fire at all just turn over.

I have a 2002 V10 F350 6.8L that I recently purchased at auction and am fixing up. I've made good progress already and replaced many of the suspension components so that the tuck drives straight. It does however have an oil leak that seems to manifest of heavy acceleration.
I'm not sure exactly where from as I have not crawled under the car, but I can see a drip land right on the Y pipe coming out the exhaust manifolds. There is enough of a drip to create quite a smoke storm under the hood. Any common areas to look for?

I have a 2001 f250 5.4 triton. My cb antenna hole leaked water in cab, soaked my fuse block. Horn goes on and off, radio turns on without key in ignition, truck only starts when key is on and I bridge solenoid, and number 4 coil is not firing. I have let truck dry out, fixed the leak. Everything is bad to normal except starting issue and coil issue.

I have a 2002 Ford F2 50 that has a diesel leak on the back of the engine. I've already replaced the drain valve that was leaking. Then I noticed that the front of the engine was dry now but the back of the engine still has some pooling With a very small drip off the back of the engine between the transmission housing and engine. Not as bad as it was of course But still a small drip. Where this may be coming from? And how to fix it?

I recently bought a 2001 f-350 xl 4 door with the 8 foot box it has the 5.4L triton v8. I was heading to a job up in northern Alberta about 10 hours away from where I live. On the drive I lost control of the truck on some black ice I was doing about 50 miles I went into the ditch but nothing crazy drove right out after. Now my truck won't do over 30 mph the engine starts to sputter and back fire I loose all my power, what's going on. At idle she revs fine but as soon as I put her into drive it's like she wants to die what can it be?

My truck: 2004 F250 SD 5.4L 191k auto lifted 3" 315/75/16 tires 3.73 rear. When I got the truck with 149k it got between 12.5-13.5 in town and 15.5-16.5 long hwy trips. Also the truck could get up and go no problems. Would easily go up hills without kicking down gears and shooting up in the rpms. Been pulling a 32ft trailer last two years and was getting between 6-8.5 mpg pulling it. The Truck is now slow to move up hill even when not towing, kicks down a lot and is getting horrible mileage. I could get 370 miles on a tank before, now I get 226 miles to a tank. Getting around 8.7-9.5 mpg in town and 10.8 hwy.
Two months ago I blew two plugs and had that repaired. (Gas mileage was falling before that happened and didn't change after it got fixed.)
Recently changed fuel filter, plugs, air filter and oil. Visually inspected MAF and I can't see any build up on it. Looks really clean.
So here is my questions... What else can I do to fix the gas issue. I am thinking about going down to a 285 or 295 series tire, but don't want the truck to look goofy with small tires on. 3" lift. So what else? Did someone say maybe the cat was starting to clog, but wouldn't that throw codes? Would a true cold air intake improve the performance?

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.

So I've been having this problem that sometimes when I am turning the truck dies. It doesn't stutter or anything it just shuts off and will start right back up. It doesn't do it all the time either. Was also having an issue where the windshield wipers would shut the truck off too. But I don't think that's the same problem.

I have an 03 f250 5.4l that I've been having some problems with. When the engine is cold it will drive fine and everything. When it warms up, if I go to put it in gear it just dies right away. Why?

My 1997 F250, 4x4, 460, auto has started dying with no warning while driving from 5 to 30 miles. Changed the fuel filter and the fuse under the hood. Where to start.

5.4L f250 is dead. Went through a small mud hole and the he truck just died. The muddy h20 was about 1/2 way up on my tires. After getting pulled out I checked the air filter and its dry. I did notice that the insulation on the hood was wet towards the back half of the engine. Guess maybe the fan sprayed it up there. Tried starter fluid with no luck. Just turns over. Also checked the fuel reset and its normal. Where should I start.

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?

I have a 2005 Ford F-350 with the V10 4x4. I was backing out of the driveway and it just died. I stopped put the truck into park and it wouldn't crank. The dash lights up and everything else works but the truck will not crank. I continued to attempt to start it and eventually it turned over and ran. It has been doing this intermittently for a couple months but never this bad. I've taken it to mechanics and nobody has been able to rectify.

I have a 1999 F350 V10 and the other day I started her up she fired right up like normal but a few seconds go by and she dies.. I noticed I do have an exhaust manifold issue I have 5 total bolts broken off out of the 20. My question is could the v10 die because of an exhaust leak? Or could it be a vacuum leak? Also after I started her back up when I put her in reverse she idles real rough. I don't believe it to be a plug or coil because all are new.
