Ford F-150 (2004-2008) :: 2006 4.6L - Hard To Start When Its Below 50F Outside
I have a 2006 4.6L that's hard to start when it's relatively cold outside.
Normally, when it's warm outside, I can barely bump the starter, and it starts right up. But when it's cold outside, it usually takes 3 or 4 2-3 seconds of cranking before it starts. Even then, it has a really rough "about to die" idle, until about 10-15 seconds, and then it idles without a problem. Once it's running, it runs great.
It has 79k miles on it, and all I've done to it is put in a throttle body spacer, and a K&N filter. I've read a few posts from people that have had similar issues, that had K&N filters, but their problems have been more consistent. Mine only seems to happen when it's first started.
As far as I know, the plugs have never been changed, as with the COPs. I've heard about a vacuum line running to the throttle body may be the culprit, but haven't been able to find any more details on that, like where the line runs to, possible replacement part number for it, etc.

Ford F-150 (2004-2008) :: 2006 V8 Cutting Out / Hard To Start?
I have an 06 F-150 4x4 with the 5.4L Flex Fuel V-8. The truck has 133,000 miles on it. This morning, the truck was very hard to start. It took me 4-5 times of cranking the engine for 30 seconds or more before it started. Once it starts, it idles fine. Out on the road, the engine cuts out and the truck bucks pretty hard. The truck doesn't die, and the issue is intermittent. I changed the fuel filter less that 10,000 miles ago. The Check Engine Light has NOT come on. What could my problem be?

I've got an '06 F150 and the steering isn't right with it. It has had a heavy feel and is almost like the power assist is only working half as good as it should. It's been like this for a couple months. I 've had all four ball joints and the steering rack replaced in the last month. It had the heavy steering feel before and after everything was replaced. It also doesn't recover itself on sharp turns, I have to turn the wheel back as I complete the turn. Could it be the power steering pump? I thought it was a mechanical device and it either worked or it didn't, maybe they get weak?

I have an 06 F150 2wd with the 5.4. Today on my way home I had to cross traffic while getting on the highway and had to get on it a bit. When I gave it the gas the truck down shifted then just fell on it's face until I let off the gas a little then it sped up like normal. It normally runs great but I don't get on it much. I just don't see why It runs great until I try to get a move on.

I bought the truck last November with a bunch of issues. My most recent problem is a hard vibration at idle. No it is not the infamous misfire and stall. All timing components (chains, tensioners, guides and vct solenoids) have been replaced.
I've replaced the ignition coils, spark plugs, air filter, and fuel filter. When I'm at a stop light or just idling in the driveway I can feel the vibration in the cab through the seats and the steering wheel. I can see the drivers side mirror vibrate but not the passenger side.
I've seen posts that are saying that this vibration is normal, but it seems a but harder of a shake than normal. Would there be anything that would only affect the driver side bank and not the passenger side?
Ford F-150 (2004-2008) :: Sputters - Misses During Hard Downshift?
Strange condition? If I kick it down hard into passing gear (or downshift hard into any gear for that matter), it pukes and sputters for a few seconds before clearing up and coming to life. No issues with normal driving, or dead stop hard acceleration, just on the downshift.
I’ve got a Magnaflow cat back on there and am wondering if opening up the exhaust and reducing the back pressure is screwing with the ECU a little? Is this just the nature of the stock Ford tune and it wasn’t as pronounced with the stock exhaust as it is now? Trucks an '06 FX4 5.4L and only has 70,000km on it.
Ford F-150 (2004-2008) :: 2005 STX Hard To Start When Cold
I have a 2005 STX with 107,000 miles on it. When it is cold you have to turn the key on for 5 seconds twice then start it. When it is warm it will start like it always did. When the temperature outside is 60 or above you have to do the key thing about 5 times. I think it is my fuel pump...

How to diagnose what I think is a failing alternator?
Here are the symptoms:
- Hard starting in cold weather
- Battery not at full voltage when truck is parked (usually around 11.5-12 volts. I have been putting a charger on it some nights)
- Lights seem to dim when I've got accessories running, like heater fan, heated seats etc. Lights get brighter with engine RPM, like when pulling away from an intersection.
What's my next step to diagnose this? I did a search, and didn't see anything. My battery is probably still under warranty, so if that's the issue, it should be a free fix. How hard is it to install an alternator in a 2005 with 5.4L engine?
Ford F-150 (2004-2008) :: Wheel Bearing - Hard To Turn One Direction
Have a wheel bearing going south can it make the car hard to turn one direction. I dont really have any humming like a wheel bearing does. But i feel a little resistance every now and then when turning the steering right. I have sprayed the steering shaft joints and i can see that they are moving free like they should. And i have a less than 2 yr old steering rack. My truck has 103k miles on the original (to my knowledge) bearings. i didn't know if sometimes a wheel bearing could cause a hard to turn in one direction feel.

I have a 06 f-150 crewcab and the driverside front window is having a hard time rolling up. It goes down fine, but getting it back up you have to play with the switch for a while and then it will roll up. Having this issue? Is it the switch or the window motor?

I've recently had a small issue with my truck missing under hard load. If you're going around 40 MPH and push it down like merging it will kick back and forth and sputter and then start hitting fine again after a few seconds and move on. Possibly bad sparkplugs and/or wires?

I have an 04 F150 (4.6, auto, 4x4, SCrew) with 300,000 miles. Any success modifying existing 4X4 IWE actuators so they are always locked in?
My last set of actuators didn't last long My vacuum is too low under hard acceleration... Actuators partially engage leading to early failure.
I'd like to take an actuator apart, modify it so it's always locked in. Some loss of mileage? Other ramifications?

I am having a problem with my sliding rear glass where when I attempt to open the glass, the pull cable barely moves. When I push the close button it will eventually pull the close cable tight and close the window. (The length of time it takes to pull the cable tight in the closed direction depends on how long I had attempted to open the window, i.e. when I'm pushing the open button it looks like all I'm doing is making slack in the cable and not really pulling it open at all)
I have done some research on how to access the motor behind the seat, but have not gotten a chance to investigate further.
Ford F-150 (2004-2008) :: Rough Idle And Hard Miss Under Load - CEL Code P0306
2005 f150 5.4.
I have a slightly rough idle and can feel a miss at 1600 to 2000 RPM. Sometimes running about 65 MPH up a slight grade I can slowly press the gas pedal and the engine will begin to miss much worse, causing the truck to shake pretty bad. When it gets this bad it will slowly flash the CEL and I get a P0306 code (Cyl 6 missfire).
The truck has 148000 Miles on it and the plugs were replaced at approx 120000 by the dealer.
In the last week I have replaced the plug in cylinder 6 (looked ok) and have replaced all the COP's along with the fuel filter and the injector on #6.
I haven't been able to get it flash the CEL light or throw a code since replacing the COPs though and I am at a loss at to what to try next.
Ford F-150 (2004-2008) :: 2005 - Hard Time Moving From Park To Drive And Reverse
I have a 2005 Ford F-150 with a 4.6L and auto tranny non 4 wheel drive. I have a hard time moving from park to drive and reverse. Is there a switch that lets you put it in gear once the brake pedal is depressed? Could that have gone bad?
View 5 RepliesFord F-150 (2004-2008) :: 2005 STX - Hard / Rough Starting When Engine Shut Off For More Than A Few Minutes After Driving
My 2005 STX 4.6 fuel pump crashed a couple of months ago. A couple of days after having it replaced I started having hard/rough starting problems accompanied by a 0300 and 0301 code. I reset the codes several times and they only come back during the 3rd or 4th hard start, never while driving. The hard starts occur after the engine is shut off for more than a few minutes after driving. I have replaced the plugs, #1 COP, remaining COP boots, Cam Pos Sensor, Fuel pump drive module and had and FI. Also had the fuel pump replaced again on warranty thinking maybe a bad check valve. Again...it worked perfectly for a day and now I'm back to square one. Haven't gotten any codes YET but its only been a day. Bad injector? EGR?
