WELL I AM BACK AGAIN AND THE NEWS ISNT ANY BETTER THAN BEFORE. BEEN WORKING ALOT OF NIGHTS THE PAST MONTH OR SO AND HAVENT HAD MUCH TIME TO GET MY TRUCK INTO THE SHOP. I DID STOP AND TALK TO THE SERVICE TECH AT A LOCAL DEALER AND HE TOLD ME A FEW THINGS THAT I ALREADY KNEW ABOUT THE PROBLEMS I AND MANY OTHERS ARE HAVING. HE ALSO ASKED ME TO TRY SOMEOTHER THINGS LIKE EMPTING THE GAS TANK AS MUCH AS POSSIBLE SWITCH TO ANOTHER TYPE OF GASOLINE AND TRY ONE GRADE HIGHER THAN I WAS CURRENTLY USING. NONE OF THIS HELPED EITHER. SO WE ARE GOING TO CHANGE THE AIR BYPASS VALVE NEXT. WAS ALSO TOLD THAT FORD WILL NOT ALLOW THE DEALERS TO CHANGE PARTS UNLESS THE COMPUTER CODES SOMETHING. SO AS BEFORE I WILL KEEP YOU ALL INFORMED. AND THANKS FOR YOUR SUPPORT.

 

It's been awhile since I gave a progress(or lack of progress) report on my rough idle. Last friday my dealer arranged for the area tech rep to meet me at my home and drive with me form a cold start. It was cold (in the upper 20's to lower 30's) and we took out. He had his diagnostic tool that he plugged into under the dash. We drove around for 30 min or so with him checking various settings and wouldn't you know the thing only did it once -- then only a mild quiver. I think the truck "knew" it was being watched. They took it back to the dealer where they said it did not fail again. They changed the oil -- it was due- and brought it back to me. Next day it shok and quivered several times -- of course area rep long gone!!! The area rep assured me he would call the engineers at the Va. plant. It's been a week and I am getting ready to call them back -- I still am going to push for a main computer change --I will let you know !!
This is a great truck -- in every other way except for this pesky idle problem!!

Me too. Cold weather + exiting the highway or coming to a stop sign = dip in idle RPM from about 750 down to 500 and sometimes 400. Extremely irritating with only 7000 miles.

36racin, how did you make out with the lemon law???

 

Het all
I don't know if this will work with the 5.4 but it helped my 4.6
I took and raised the idle of my truck about 100 rpms, and it helped smooth the idle a little, and maybee this is enough. On the throttle body there is a little screw you can turn that stops the throttle linkage from closing all the way.
you will need a small vice grip to turn it because it has no slot to put a screw driver in.
Give it a try, don't raise the idle to much, just a little bit should do it. Hey if you have been to the shop a bunch of times, it is worth a try.

Well it's my turn at the dealer for the rough idle problem, I tried just about everything stated in this thread. My warrenty expires in 40 days. I want to get it in the dealer with the problem documented so if Ford comes out with a fix I can get it done.

If nothing works then we all need to band together and go after Ford. Get as many F150 owners together with this problem from all over the states and send a letter to Ford asking for resolution. There is strength in numbers.

Comments ?

Just had my truck in today for hesitation problem cold, between 45-65 mph . Hope this clears up the issue. Here's what the service people say " There is a TSB on a heater hose leaking on one of the coils ( #4 ?)which causes a short and your problem. Part has been ordered and will be a week to get .

Guys where is the wiring harness next to the a/c condensor. What does it look like. How do I re-route it, etc. My truck runs great but it will sometimes miss really bad at idle until I step on the gas and then it clears right up? I have a 4.6, superchip, K&N, Flowmaster system. Any and all help would be appreciated.

WELL I AM BACK AGAIN. MY TRUCK HAS BEEN AT THE DEALER SINCE TUESDAY 11/28/2000 SO THAT THE COULD TRY TO SOLVE MY IDLE PROBLEM. THEY REPLACE THE AIR BYPASS VALVE TO SEE IF THAT IS MY PROBLEM. I HOPE SO!!!!!
ALONG WITH OTHER PARTS FOR OTHER PROBLEMS THAT I WAS HAVING. I WILL LET YOU ALL KNOW WHAT HAPPENS.

 

36racin, I hate to say this -- but I am still workin to get mine fixed as well.The next step the dealer is going to do is to hook up some recording device to my truck--(refered to by them as a "flight recorder"). This gizmo will allow me to punch a "record" button when the roughness is occuring. I assume this is some sort of a portable hard drive or something, cause they have to hook it to their shop diagnostic machine to download and diagnose. I asked the people at the dealer how long they have had this thing an they said "since 1996 or so". It is therefore sort of older technology. It will allow me only to "record" 4 "events". I guess it will be up to me to decide when to push the button. I can't understand why they didn't suggest this thing earlier -- I have been complaining of this problem since I drove the truck off the lot -new- 15,000 ago!!
Mine seems to happen when the truck is in the "transistion" period -- sort of warmed up -- but not fully. I live in a small town with a lot of hills and stoplights-- so this naturally happens to me alot on my short jaunts around town.
That thing they are replacing on yours sounds like what they did to mine (didn't help) --idle air sensor?
I'll let everyone know what happens!!

The more I read this the more I don't get a good feeling that this will ever get resolved. Knowing how many f150 trucks are on the the road I wonder how many have this problem, It cant be us, are we that sensitve about our truck's.

 

GOT MY TRUCK BACK FROM THE SHOP AGAIN TODAY AND AFTER THEY CHANGED THE AIR BYPASS VALVE IT STILL HAS THE ROUGH IDLE PROBLEM. BUT NOW ITS EVEN WORSE THAN BEFORE. SO I WENT BACK TO THE DEALER LATER AND RETURNED THE TRUCK TO THEM SO THEY CAN TRY SOMETHING ELSE. BUT TAKING IT THIS TIME QUALIFIED MY TRUCK AS A LEMON BY LOUISIANA LAWS SO I WILL BE CONTACTING MY LAWYER ABOUT MY PROBLEM. ONE WAY OR THE OTHER I WILL GET MY TRUCK FIXED. I DIDNT SPEND $21,000 ON A TRUCK THAT RUNS LIKE MINE DOES. SO AS BEFORE I WILL KEEP EVERYONE INFORMED. AND THANKS FOR THE SUPPORT

 

racin36, what year is your truck?? I'm not sure if the lemon law is the same in MA. But I was inform I could not go after them because its a characteristic of Ford.(meaning it's common on F150) Lemon Law here in Ma states, it has to be a safety issue or if it would effect the value of the car. Let us know how you make out.

 

Well if this is a common problem with the F150 Ford does nothing to inform their customers of this, and that would be missleading the consumer. If that is how Ford plans to do business then maybe we need to take this problem to Ford.

 

MY TRUCK IS A 1999 AND HERE IS THE LEMON LAW FROM THE OFFICIAL ATTORNEY GENERAL'S OFFICE FROM LOUISISNA. WHAT DO YOU ALL THINK?????????

What is the Lemon Law?

The Lemon Law states that a manufacturer has a legal duty to repair a new motor vehicle. The Lemon Law does include newly-leased or demonstrator vehicles, and does not include motorcycles, RVs or mobile homes and program mobile homes. A "lemon" is defined as a new motor vehicle that has a defect which substantially impairs the use and/or market value of the vehicle -- this does not include defects caused by consumer abuse, neglect,or unauthorized modification of the vehicle.

Are there any additional stipulations such as time when defining a vehicle as a lemon ?

A lemon automobile is one which does not conform to the express warranty and cannot be repaired after a reasonable number of attempts -- at least four repair visits to correct the same malfunction during the warranty period or within one year of delivery of the vehicle; or if the vehicle has been out of service for repair for a combined total of at least 30 days during the same period. If the defect still exists, the manufacturer may replace the lemon with a new vehicle or may give a full refund.

What steps does an owner take when seeking a replacement or refund far a lemon vehicle?

A buyer must first use the free mediation or arbitration procedures that the manufacturer has set up to deal with complaints. Be prepared by keeping all receipts for car maintenance and repairs, letters from mechanics and all records on the vehicle. If all else fails, file suit with an attorney.
