Hello...Well I do hope you have better luck thatn I did with the flight recorder...I ran that on mine for a week and I took three good pictures of the truck rocking and rolling real bad...they went over the data and of course the data showed no problem...I believe there is a main problem in the computer and it is not recording any errors when they occur...so no recording of errors no information for the flight computer...my brother has an identical truck to mine...same year and same options and his runs as smooth as a baby's butt...he gets 17 to 19 miles to the gallon...Mine runs rough and I get 12 to 13 miles to the gallon....he has 20k miles on his and runs sweet...mine has 17k miles on it...he did have to have the head gasket changed on the passenger side for the oil leak but that is it and his runs great...mine has just developed the oil leak and runs bad...so there has to be something in quality production that has been overlooked and some of us got the random luck of the draw and got what ever is causing the idle problem...please keep me posted on this as i am like all of you total frustration...oregon's lemon law is similar to the rest of the states...great on paper but good luck getting anything done...

thanks guys

steve

I have a 2000 4x4 with the 5.4L. I have had this problem since day one although it was tolerable (Could barely tell it was idling rough)when I perchased it. It has become significantly worse I currently have 14500 miles on the truck. I take into the dealer tomarrow so I will keep you posted.

Should have bought the Tundra!!!!

Actualy I still like my 150. I just REALLY would like it to run right exspecially after shelling out $30K.......

 

I'm with Black Venom. Mine has had the rough idle since day one. Just the odd hiccup and feel of a drop in RPM that gives it that bit of shudder. Not much, mind you, but definitely got the Jurasic Park thing going on the surface of the coffee in the cupholder. I just put in a Gibson Swept Side and K&N Fipk. I did the computer reset and I gotta tell you, the exact same feeling is there but it feels like it move a few blocks away. Very distant and slight now. Still feels like the exact same thing but instead of a 5.0 it now feels like a .5 on the Richtor (if that makes sense; same miss/stutter but distant and soft now, almost to the point of imperceptible). I can't wait for the computer to finish learning to see if it comes back in full or if perhaps it'll remain as the vague and distant thing it's become. We'll see.

I'm baaaack,
Went to another dealer as the "area service rep" (John Dietz) suggested. As soon as they got hold of it they said they felt it and there was a problem. Great I thought - then we hit the uncooperative wall known as "ford". The dealer has the latest and greatest diag. tools. After putting it on their sensors and running their tests; I think they did some things as they billed Ford $80-some. They called ford on the "hotline" and here's what Ford said -- (sit down - as you may fall down laughing!) "this was characteristis of the 5.4 and the reason was the camshaft".
My big question is that if it is the "design of the 5.4's camshaft -- why does it not do this all the time??. I called the dealer back and asked them to call the "hotline" back and ask "why not always?".
This is where it stands now for my truck. I will let this site know what happens next!!
Again this dealer as well as the dealer where I purchased it from, has been very courteous!

I am glad I found this site...I have been browsing all the problems everyone has been having since I found it back in Nov. I too have had the oil leak and rough Idle on my '99 F150 5.4 for almost 18 months now and have been to two different dealers. Had the #4 coil pack replace because of the heater hose leaking and had the passenger side head gasket replaced because of the oil leak. Last time it was in for the rough idle in Nov they replaced the throttle body. Needless to say when I drove away the vibration was still there. Yes too mine knocks when cold and has the same problems everyone else is having.

I called the ford customer service number to find out about the TSB's about my truck. I went to www.alldata.com and printed out the list of 42 TSB's for the 99 F-150 with the 5.4. Now after calling the customer service number and telling them all the problems with my vehicle and wanting the TSB info they put me on hold. The girl came back on and said she had to research it and get back with me. She called me back 15 min later and told me I needed to get ahold of the Dealer and make an appointment to bring my truck in to get looked at. I WAS EXTREMELY PISSED OFF. All i wanted was info on how to get the TSB's to look at and now I had to take my truck to the dealer after they called me 3 times to set up an appointment. Well needless to say they have had my truck for two days and low and behold I get the same old line "charateristic of this engine." Which is bull.

They gave me another F-150 to drive for a couple days with the same motor and it does not do it. We have a 2000 F-250 at work with the same motor and it does not do this. 5 of us at work all have the same trucks of different years and none of them do it. My brother has a 98 F150 with the same motor and his does not do it.

I have a freind that works as a quality control supervisor at the Lorain Ford Plant that builds the Fullsize Vans. He told me that Ford had a major problem in the beginning of the '99 model year with bad 5.4 motors. Well mine was made in 10/98. He told me if I could not get the problem fixed at the dealer to get ahold of him and he would have me bring my truck to the factory and hook up to the diagnostics they use at the end of the line before the vans go out the door. He also said he would get ahold of his engineer and have him there. He said the diagnostics the dealers have are junk.

I am getting extrememly annoyed at the run around I am getting from ford. I have always drivin fords and everyone in my family has since as long as I can remember. Hell my uncle retired from ford. I am about ready to drive the 2 hours to detroit and drive this thing right through the front door of the Ford Headquarters and choke that bastard from the tire ads saying how they are working to replace all those firestone tires. Quality is job 1 my butt. I have a 3 inch high stack of printouts from this board I am taking to the dealer this morning to show them that I am not crazy. The local dealership that would not look at my truck anymore since I did not buy it there has been replacing engines left and right for the oil leaks and the rough idle problem. I cannot even get the 2nd dealership to give me any other information.

Does anyone have any information on what to tell these bastards to get them to fix this problem or give me a new motor? I am also checking into Ohios lemon law to see how all that works.

Wish me luck

 

sorry I hit the button twice

not to make u feel bad but not all 5.4's are the same u may have a 99 and so may your buddies but often the pcm calibration codes are not the same which can result in some differences. I know my truck runs rough at idle too and my moms doesnt, its a 98 non pi head mind u. I have also seen 00 5.4l run the same as mine and many others as well, i was told that at idle the engine will go into lean misfire, i checked my plugs and they had a white tinge to them which does show a lean conditions, fuel pressure and injector flow all ok, mine has had a new egr valve put on, reprogrammed pcm, replaced plugs, intake gaskets (when head oil leak was done)and it still will run rough escpecially after letting the vehicle idle for longer periods of time, so maybe it is the pcm lean misfire control, have any of u heard of this?

 

What is a "non pi head 98" ???? Help!!!!

I am thinking that this problem will be un-resolved until we can get a engineer on it. Could it be a issue with the Triton part of the motor, Do other 4.6 and 5.4 have this problem ?, I have not heard any Mustang or Town car owners with these problems.

The Ford F150 and Exdedition both have a 4.6 Triton motor, the Mustang, Town Car and New Esplorer have the same moter but does no have the triton part. it is the part that allows the motor not to over heat if coolent ran out.

Thanks Donw,
I knew they had that capability, but I did not know that was why they called it the "triton"

I know the system is not called Triton, but only F150-F250 and Expeditions have this system.
