Ford F-150 - 1997-2003 :: 2000 - Run Rough - Big Hose At Rear Of Upper Intake?
Mar 5, 2015
I just replaced the engine in my F--150 with one from a van that had only 60K miles on it. It still runs rough and misses. Not as bad as the earlier engine that had dropped a valve. While trying to find the problem, I moved a large vacuum? hose at the rear of the engine maybe 1 inch diameter and it nearly fell off the barb at the back It is also connected at the other end to some type of small metal can. When I pulled on this it fell off and the engine died.
Also need the smaller 5/8 in diameter hose at front of air intake tube. I need a size or a pert number for this hose as I cannot crawl back onto the motor very many times due to a spinal problem. I would like to get this hose and then get under the firewall only one time. I am having issues with this truck, bought is used at auction running rough. Replaced engine with one that was supposed to be a good one, but it runs rough again..
I need to add that New platinum [plugs were installed and the coils were off the old engine that had maybe 50 miles on them and were from NAPA. I only hope htis hose is my problem. However I cannot find any part number or anything on it...

I have a 1998 Ford f150 4.6 2x4 i have a coolant leak on the upper intake. It comes out on the back left of the intake through a metal pipe. Well where the metal pipe is (pressed in) to the intake. Now i talk to the guy at ford dealership in the parts he said it is called the (heater pipe). He also told me that the part is 21 dollars but I have to press it in and if that does stop the leak he said I would have to buy a new intake. Now here is the problem I can not find any info regarding this heater pipe. I don't know how to remove it properly, why it is leaking. I can't find it in the handbooks that i have read so far.

Our 2000 explorer xls 4x4 with 4.0 ohv just pop the code for the intake gasket leaking. My question is, would there be any way to tell if it is the upper or lower that is leaking? It has 188k on it but still runs good. I think I can feel a miss in it at idle but it is not a steady miss.

I have a 2000 F150 with 5.4 L motor. The last two trips I have had the top radiator hose come off while under heavy load (pulling a long hill) after 5 hours of driving. So far I have flushed the radiator, checked the thermostat, and refilled with G05 Gold and distilled water 60/40 ratio. I do not hear any gurgling in the heater core. Heater seems to work great.
The stock temp gauge shows it right in the middle range between Hot and cold, right before it blows the hose off. I have replaced top and bottom hoses and put new stainless steel clamps at all end except the top, where I am using the OEM clamp that came with the truck. I thought about replacing the top clamp as well but did not want to blow out my radiator, if in fact it is developing high pressure.
Do these clamps get weak with time? Should I use a vacuum attachment on the fill/overflow tank to remove all air before refilling?

I have been having some issues with my 97 ford f150 4.6 liter, started out running rough, then hydrolocked with no serious damage, blown intake manifold gasket, fixed that, alternator over charging do to bad voltage regulator, fixed that. and airbag code 52, still working on that, as well as failure to connect when trying to do diagnostic scan. now I am wondering if the engine diagnostic is still even working. still running good just a very slight vibration when warms up. I am not getting any code. or my check engine light is not showing any codes. What I want to do is force a code. What would be the safest way to force a code or force engine light to give a code?

We have a 2002 F-150 4.6L 4x4. The engine went bad and we bought a new engine (remanned ATK). Had this engine installed and a year later it was bad and was determined it was a manufacturer defect so they sent a replacement engine under warranty.
We had this new engine installed. The mechanic fired it up and it backfired through the intake. They claim that the compression is good, the fuel pressure is good, and the timing is correct. Can they check these things when the truck is not running? The mechanic is completely frustrated with the situation...
Everything I read leads to a timing issue but they say they checked it so before I go in there screaming I want to make sure it couldn't possibly be anything else...

I have an 03 super duty with the 6.0, came back from vacation with my 5th wheel in tow. Lost the upper turbo hose twice on way home. Managed to get it rigged and made it home and parked it. a week later went to uncouple and move the truck and had some very strange issues. Started fine but could barely make it up driveway (no trailer at this point). No power, felt like when turbo hose came off. Got it moved and checked turbo hose and all was good?? Went out a couple days later and no start.
Checked all relative fuses and relays and all checked good. Jumped starter solenoid and starter worked fine. turned key on and jumped quick connect on right side of engine compartment to battery and it fired right up and ran. Jiggled shifter around in park and neutral and nothing. BTW I always here the relay clicking and swapped with one of the others just to be sure, same thing. After looking on the internet for a day and a half thought maybe a NSS in the tranny but I think I have the 5R110 that does not apply??

Well I was fueling the truck today and I opened to hood to check it out and noticed that there was no pressure in the cooling system by squeezing the upper hose. I did have a spare degas bottle cap and removed the old one slowly and replaced. I have been driving over 30 minutes and it is close to 100 degrees.
I then drove on down the road, the truck is not getting hot. I stopped to look at some running boards and the truck was running and then I came home and still no pressure, the truck is still running, I removed the cap and no pressure, I then removed the small hose going to the top of the degas tank and no coolant came out. I turned the truck off and disconnected the upper hose and some coolant did come out.
Is this normal? The truck runs just fine, just has me worried. I just bought the truck and the previous owner recently replaced the water pump, T-stat, hoses, etc. All parts were bought at O'Reilly. So everything looks good.

So I have a 2000 Echo with about 129k miles on it. I parked it in my driveway for the winter to drive my SUV in the snow (I live in Wisconsin).
After a couple months of the bite of the gas mileage difference I dug her out and noticed that the drivers side rear wheel was locked up. I presumed it was simply due to it sitting in snow for a long while. So I jacked up the rear, popped the tire off and WHAM, a rusted through pipe falls flat on the floor of my garage.
I trace it back to a port right behind the fuel intake - tho not the main intake line itself. I then find its other half, still connected via rubber tubing to a black hub of sorts.
Here are some pictures with a vision of what I am talking about:
The entire hose in two pieces:
The port where the hose was connected by the fuel intake:
The port on the hub where the rubber sided other half of the hose connects:
The hose pieces side by side on the trunk of the car for scale:

2000 Ford F150 1/2 ton 2x 5.4L... Last year, I started having a problem where when the temp dropped below 50 degrees outside, my F150 would idle really rough and sometimes stall out. The CEL came on and reported some codes that I don't remember but pointed to bad air/fuel mix. I consulted a friend and he suggested changing out the IAC. I did that just towards the end of the cold weather spell we were having and the engine ran great so I assumed it was fixed.
Well, the temps have been below 50 for 8 days now and ever since the temps dropped the problem has come back. I took it to AutoZone to have the codes read and they gave me the following:
P1151 - Lack of O2 switches -bank 2 sensor 1 : ECM could not adjust fuel trim because of a lean or rich condition
AND
P0171 - Fuel trim bank one condition : The powertrain control module uses the oxygen sensor to calculate the Air/Fuel ratio of the engine. The computer recognized a rich or lean condition on one engine bank only.
Both printouts that they gave me mentioned the following:
Poor fuel pressure
Bad or Malfunctioning MAF sensor - Dirty/defective
Oxygen sensor defective
Fuel injector problem - Leaking or fuel pressure high/low
Vacuum leak on engine
I again called my mechanic friend and he suggested cleaning the MAF and if that didn't work replacing the MAF. I cleaned it and the problem was better but still not fixed.

I went thru a 100 posts on "Intake gasket" search but I couldn't find any repair information on the 4.0L intake gasket replacement. I'm having difficulty pulling the upper intake off. All nuts and connections have been removed except for the egr tube that's connected to the upper intake.
According to another site, u should be able to just pull straight up, clear the intake studs, turn the intake to the left and then up due to the fact the egr tube is curves inside the intake towards the front of the upper intake. No luck. egr tube won't separate from the intake. This is a little long but everything has been disassembled to this point. BTW this is a 4.0L OHV engine

After chasing the smell of coolant for a couple weeks, discovered that the upper radiator hose was leaking at the engine. Based on my schedule and drive schedule, and unfamiliar location this last week, I took my truck to the last people I wanted to - the Ford dealer, where they attempted to charge for the hose replacement. During this time I discovered the nature of how these hoses work and asked the tech why they don't just replace the O-rings ... "Ford Motor Company wants to sell you a new hose with labor" - a direct quote from the Ford tech. And that is why Ford is the LAST place I want to go for repairs I cannot perform. I kept the old hose - any spot where you can get the O-rings alone?

I'm in the process of changing my upper and lower intake gaskets. my question is, the upper intake along with the tubing on the fuel rail are caked with oil/carbon, along with the back side of throttle body. What would be the best way to clean them?

2001 F-150 4x4 5.4L. I am going to replace the upper control arms this weekend. I noticed that there are regular bolts with no cam washer installed. I have read conflicting info on whether the cam washer set up is needed. Do I have to install these or can I just put the old bolts back in just like they are. When I replaced the uppers on my 1997 T-Bird I put in new bolts but there was no mention of a cam washer setup for it anywhere that I saw. What would be the problems if I just reinstalled the old bolts. Right now the truck drives straight as an arrow but the lower ball joint on the driver side is shot so I will be replacing it also.

My daughter returned from college with her 2000 f150 4.2 idling and running rough on acceleration. It is throwing a P0171 code only. I replaced the isolator bolts/plenum gaskets four years ago because of a P0171 & P0174 codes.
So far I have replaced the MAF, new PCV valve and elbow, checked all obvious lines for vacuum leaks (though I suspect a leak somewhere still). Also, a quick check of the plugs show some lean color/deposits on the drivers side only. Any thoughts or troubleshooting I should try next?

I have a 2000 E350 boxtruck with a 5.4 auto. The motor is a new rebuilt with about 4000 mile, coils were replaced with motor, injectors were rebuilt with motor.Today (500 miles from home) the truck died. I was going up a slight hill on an interstate. It will still start, but runs very rough and when I put it in gear and step on the gas it dies.
So I had it towed to a garage. While pushing it into the garage I noticed my gas cap was missing. I know it was on 45 min earlier because I got gas. Did I forget to put in back on? probably.. But I wondering if the missing gas cap could cause the truck to run bad,vary bad?

I own a 2000 f-150 7700 series with a 4in body lift. recently Ive had a problem starting (I believe it is from the shifter not recognizing im in park) but now my theft light flashes at me and there is a weird sound that sounds like a relay from under my steering column when i roll my windows down, move shifter around or turn on 4x4. also my radio stays one every once in a while after the key is turned all the way back to off, and windows wont roll down after i hear the relay sound. Ive read to tighten shifter linkage and will do that tomorrow to see if that fixes it.

I've got a 2000 f150 with a 5.4 and 135,000 miles. The other day it was driving fine then i stopped and got gas and after that it was boggy and running rough so i thought bad gas but i ran through that gas and got more at a different store. The cel came on i got it checked it was misfire cylinder 1 so i put new cop, spark plug, and injector. Unhooked the battery and then the light came back on so i ran the code and now im getting a p0171. I checked the pcv and sprayed around the intake and vacuum lines. I also checked the pcv hose and elbow in the back and i found nothing its a fairly new hose. So, it does run rough it shutters a lot.
