Ford F-150 (2004-2008) :: Truck Idles High And Rough In Any Setting From Park To OD / Stopped Or Moving
Jul 6, 2015
I am trying to solve a mystery on my mom's truck. It's an '06 4.2L F-150 STX with about 133k miles. It had a check engine light on until today- I cleaned the TB and changed air filter yesterday, and both were filthy. Code vanished later on while driving.
I want to check the PCV because the truck idles high and rough in any setting from park to OD, stopped or moving. Worse when stopped though. Entire coil pack has already been changed due to previous misfire problems. This feels similar to a misfire but without the acceleration hesitation. It has also had a recent oil change, and fuel/oil filter change as well.
There is only one hose connecting to the intake on this truck, and it appears to be a vapor line of some sort to the valve cover, but isn't a PCV cause it's just a hollow tube. There is nothing else coming out of the TB at all, except for the throttle control cable. I don't even seen any nipples or connections or holes where a PCV hose or valve should go. I thought it was on the passenger side, under the TB... but there is nothing here at all. I'm stumped.
I am beginning to think the truck just does not have one at all, which I know for a fact is impossible. I have traced every line on this motor from top to bottom, and I do not see it. Should have a heater on it I assume? What else can make the truck so rough? I don't buy it that "it's just that way". That is complete, lazy, BS. I have had/driven many trucks; 4x4s, supercrew, diesels, jeeps, dump trucks... I have NEVER had a truck run as badly and roughly as this one does. Heck, a twin-turbo 700HP diesel doesn't run this roughly.

I have an 07 f150 v8 5.4 and it idles very rough. When i start it it seems to start really rough and just about everytime im stopped its shaking just enough to annoy me. Do you think its the spark plugs? I took into the dealer about a month ago and they said everything was fine. But its still doing the same thing. Also the A/C tottaly sucks is that they way it is? When I accelerate the cold air gets kinda warm and it doesn't get cold until i get up to speed.

So my "farm truck" is idling very rough, to the point that sometimes that it stalls out. At high idle it runs fine but when its at a idle its very rough. Its been running fine until probably a month ago or so and its just getting worse. What it could be? I am thinking it might be that something is dirty but i just dont know where to start with figuring out what the problem is.

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?

I have an 05 150, 5.4l, My truck idles around 600 rpm when warm, I think that may be slightly low. Not sure what to check on.

I have a 2008 F-150. When moving gear selector from park to either reverse or drive, trans has a delay engaging. After engagement, it runs fine, shifts ok, downshifts ok....

I recently replaced the plugs cuz I had a rough idle all the time. During plug change when I discovered they had already been changed I found one that had a burned off electrode. Does this mean a lean condition exists?
After plug change it runs smoothly but only after 10 min warmup in our canadian winters. I can drive it when its not warm but seems to have less than full power and idles very badly after driving w/o proper warmup.
Next I changed fuel filter and checked fpdm, it was a little rusty but not bad so i just mounted it 1/4 off steel to prevent further rusting.
Since then I have installed a programmer [diablosport] but found no codes since i had battery disconnected for filter change. no new codes in last few weeks since.
So do I have a lean running cylinder causing this poor cold idle or a rich cylinder? It must be a clogged or dripping fuel injector right?

2004 f150, Column shift Auto...
Today I stopped the truck put it into park and shut it off, everything worked fine, when I went to go start it back up it started but I cant put it out of park, I called FORD and they said put the key into the on position press the break as hard as you can and put it into neutral, we tried that and it didn't work, then they asked if we could move the truck because it could be struck or something still nothing... We tried the little cap and hold it to override the solenoid but it didn't work I dunno if I am doing it wrong so Is there any other things I can try or can you walk me through the override button here's what I did with that.
Opened the cap with a flat head
pushed it in
And started tried to shift
Is that what you do or what do you need to do??
Is there any way I could check the solenoid how do i take apart the column to do that?

Just got an 04 f150 STX 4.6L Regular cab.
Drove fine for a few months (she's a little rough, but she does the trick).
The other day, I went out to go to work, truck would start and run, won't come out of park. Both turn signal indicators on the dash are illuminated, turn signals, flashers, radio and Climate controls do not work.
Currently driving with the emergency shifter release pulled out and zip tied open. First thought was interlock switch, but I'm not sure if that would affect everything else.
This happened once before, and I pulled all the taillights and checked all fuses, then it just seemed to work again after flipping the rheostat for the interior/dash lights. didn't work this time around.
Dash is all torn apart - where to start looking?

An injector stuck open on my 05 5.4 and bent a rod. I had a new rod put in and all new revised Motorccraft injectors. This was about a month ago. Truck has ran great for the past 3 weeks until today I put it in park and it idles real rough, put it in gear and it smooth as butter again? (Once in a rare while it will continue to idle rough in gear for a few seconds but then clears up.) New motorcraft plugs were put in right before it bent the rod. The truck runs real strong other wise. I am about done with ford this pickup has been the biggest pile I've ever owned one thing after another and just when I think its fixed its some other stupid problem. I'll start by cleaning the maf and throttle body. Could it be a bad coil?

My 05 f250 v10 runs rough at points and sometimes quits when driving. I find it too that I can't rev it in park or neutral and sometimes when it is cold I can. I was wondering if it was a tps or something with the intake...

I have a 2006 f150 fx4 4x4. I drove it home from work yesterday and it ran and drove just fine. I got up this morning to go to work and turn the key but the engine won't fire. I turns over just fine. I turn the key to release the trans to put it in neutral to see if it would start like that and the shifter is stuck. I button in the front will not go in. I tried lifting the rear tires off the ground to see if I could free the trans.

My truck gear shift is stuck in Park (console type). I have been reading threads that discuss potential causes such as blown fuses, bad brake switch, bad brake shift interlock actuator, and even ignition switch. All fuses are okay. Before I try to get into all the other possibilities, I have a question around what the local auto parts worker suggested. He said that there is a small plastic piece that may have slipped down interfering with gear movement. This could make sense, especially since the white manual release lever doesn't seem to be moving.

My son who is away at college, has a 04 F150 that has a center console and he can't get the truck to shift out of the 'Park' position. I told him to try and rock the truck back and forth and then try again...no luck.

I have a 2008 fx4 with 75000 km it runs great but when I go on a long ride up hills or tow my trailer it acts up only when I get to my destination. the engine will run really rough and knock loudly seems only when I use reverse or sometimes park (and oil pressure in dash looks good),and if I shut ignition off and restart it no problems till I make engine work hard again.

I just started idling high in park and while driving I cleaned the throttle body and the ics but did not work I pulled the ics out and had some one turn the key on and off and the ics plunger does not move I can feel the ics motor moving but the plunger does not move while i had the ics out I pushed a rag in the ics hole to control the idle and the idle came down but the ics plunger still doe not move would that mean the ics is bad?

My friend just bought a 2008 F150 5.4 110k, it ran great all day during all of the test drives, after he gets it home it has started acting up. Most of the time it runs great, but sometimes when you stop the truck the idle will drop down and the truck sounds like it is going to die but so far it hasn't actually died, it starts knocking really badly and runs very rough. If you let it keep running like that it sets P0340. If you rev the truck up it cleans up and sounds fine again and it will even drop back down to a clean idle most of the time. I swapped the cam sensors because it was easy and just to see and it didn't make a difference, I was hoping after switching the sensors the code would switch to the other head but it didn't.

My 04 F150 has started having a rough idle. While in park the engine will stall out with the A/C off. Also when in drive the truck will idle close to 1000rpm's. I had to the fuel filter cleaned and also the MAF sensor cleaned. Also did a vacuum check on it. Pulled the code and it's throwing a Lean Code. What else should I be looking for?
