Ford F-150 (2004-2008) :: 2005 - Running Rough And Misfiring Quite Frequently
My 05 was running rough and misfiring quite frequently. After much deliberation, I took it in for a diagnostic hookup. The dealer said my driver side cat was clogged. Lucky for me, I was just under the warranty period(79673 miles). I have had it replaced and I can feel a noticeable difference in the way it runs. Could a clogged cat have made it run that poorly or am is it just in my head that it is running alot better?

Just did the timing chain, phasers, oil pump and lash adjusters on my 05 5.4 s-crew. Always had a bit of a rough idle but now it's worse. If the truck idles for an extended period it sets a p0300. Just off idle the misfire is gone. It does seem a touch down on power but otherwise runs great. I did have the plugs out during the work. I cleaned them, applied anti seize and re installed. The previous owner had the plugs and COPs changed 10k miles ago. Plugs are motorcraft and coils are aftermarket.
I monitored with oreillys crappy scan tool and the miss only happens at idle. It is not a dead miss; unplugging COP on each cylinder still makes it worse.
Truck idles warm at like 570 rpm and if I hold my foot on the pedal to raise rpm a bit miss goes away.
Each cylinder is logging misfire counts with no rhyme or reason. The only thing odd during the timing job was 4 spark plugs were partially loose.
I'm sure the timing is correct; I used the OTC crank tool and for timing kit. Truck has 150k, front 02s are fairly new...

I recently replaced timing belt and balance belt on my 2004 santa fe 2.4l and now the engine runs like crap and shakes badly. I went over all timing marks again and again and I am at a loss.

My daughters 2004 f150 5.4 3v. 130k miles. Had a broken timing chain guide on passenger side. Changed phasers, solenoids, timing chains, crank gear, tensioners, and oil pump. Pulled pan and cleaned it and the pickup tube of pieces of the old guide. Engine had zero sludge. Very clean inside.
Put it all back together. Left crank sensor unplugged to rotate engine until it had good oil pressure which only took a few seconds. Plugged sensor back in. Truck started right up. Runs perfect. Drove perfect. Idles with no noise. But as soon as I rev it up a little, there is a HORRENDOUS squealing from the lower left of the engine. Pulled serpentine belt and squealing is still there. Used a stethoscope to determine its in the lower left behind the timing cover.
I haven't pulled the cover back off yet but what this could be? Everything went back together fine so I can't imagine what it is.
HOWEVER, I did notice that my new tensioners only had an oil hole in one of them. The two I removed both had an oil hole. So one of the new tensioners does not have an oil hole in the center of the plunger. I see online, that many did not come with an oil hole. But I'm wondering if this could be the source of the squealing? Maybe not oiling the chain enough and the squeal that I hear is the chain on the plastic guide?
Ford F-150 (2004-2008) :: 2006 - Running Rough When Warm
History: Truck was running okay but acted like a coil was bad when under load. I changed out all the plugs with Motorcraft and put on Summit racing COPs.
After the plug and cop change the truck will run rough after it is warmed up. I changed back to the old COPs and it runs the same.
First I replaced the MAF sensor after finding many posts on here about it. No change.
I read a bunch of posts on oil causing the problem so I used 10-30w and nothing changed.
I searched for a vacuum leak with carb cleaner and couldn't find one. I removed, cleaned and reinstalled the throttle body.
When I did the plug change I disconnected the PCM without disconnecting the battery. Would this cause this type of problem?
I think this is about all the stuff I found to try in the threads that came up through searching.

I have a Ford F150 XLT. I have 67000 miles on it and the other night it just started running rough out of no where near idle. Once you got over 20mph the rough running would go away. I took it to get an engine change and engine flushed but it came back. It doesnt always run rough near idle or below 20mph. The Ford dealer says my engine has only 22 psi oil pressure near hot idle and cant engage the VCT phazers and they want to replace the whole engine.
View 1 RepliesFord F-150 (2004-2008) :: Running Rough And Skipping After Plug Change?
I just completed a successful second spark plug change, using Motorcraft SP515 plugs just like last time. After reconnecting battery and starting engine, it ran poorly throughout a short road test. Felt like it was skipping. Checked under the hood and found that the #2 fuel injector was disconnected, so I reconnected the injector.
I took another short road trip and it still ran poorly as if skipping. So, this time I disconnected the battery for several minutes while removing the #2 plug thinking I may possibly have fouled the plug by the injector not being connected. I also checked all of the other injector and coil connections. Reconnected battery and took another short trip. It still runs poorly. No codes yet.
Ford F-150 (2004-2008) :: 2007 - Motor Start Running Rough At Low RPM
I have 07 sscrew with 5.4. 93,000 miles. At start up truck runs perfect. After 20-30 minutes of running motor will start to start running rough at low rpm. Diesel sound. I can rev up and motor clears up and idles fine. Should I replace VCT solenoids? Or phasers? Or both at one time??

I just bought a 2007 F150 XLT with a Triton 5.4 with 80,000 miles on it. My problem is this, the engine seems to run ok ( a bit rough) until it gets up to running temp and I have driven about 10- 20 miles then most of the time, it starts to act up.
When I am driving it is fine, but when I slow down and come to an idle about 500rpms, it sometimes runs very rough, sounds like a diesel and shakes violently. It feels like it is doing damage. Sometimes it stalls. If I rev it back up immediately it will smooth out.
In speaking to some friends they've suggested things from plugged oil channels, (affecting the cam phasers? All the way to it needing new chains, phasers and guides. I don't want to spend a ton of money doing an improper service repair only to have the issue show up later . But there seems to be a lot of different answers to the same problem. Is the dealer going to be able to diagnose something like this fairly well? Or should I try to narrow it down a bit first?
Ford F-150 (2004-2008) :: Running Rough / Ticking Noise / Low Mileage?
the F150 of my brother has the follow diseases:rough running ticking noises, low mileage per gallone, blue smoke out of exhaust after start, i have ordered the cam phaser, hope, that will be the reason. But today, my brother means, i have to do a test drive, because the truck has no power. and really, feels like missing of one or two cylinders. Very bad performance. Is it possible, that the reason are the phasers?

I just had my 04 5.4l engine rebuilt. Ive driven it about 500 mi and it started running rough at a stoplight. I tapped the accelerator and it started running good again but service engine light came on. I pulled the codes and they were P0022, PO345, P0340,and P0430. It has done this several times now. Everything was replaced including the phasers, except for the camshaft sensors. Could they cause this problem?
View 3 RepliesFord F-150 (2004-2008) :: Running Very Rough / Shaking At Low RPMs - Truck Died
On my way into work this morning, my 06 with the 5.4 started running very rough/shaking at low rpms. I could kick it out of overdrive and it would smooth out and seemingly be fine at higher rpms.
This worked out for a couple of miles until the truck just died on me completely. The Edge is showing po351, 352, 353......358 codes. Ignition coil Primary/Secondary circuit fault on every cylinder.
I'm thinking its unlikely that every coil failed simultaneously....computer? When I try to start the truck, it will try to hit on a cylinder or two, but will not run.
Ford F-150 (2004-2008) :: Running Rough - Rear End Squeaks All The Time When Going Up Or Down A Hill
I have a 2004 Ford F150 with 149,000 miles I have recently put 5,000$ In the motor that is a 5.4 V8 before it would shake and make a terrible noise got a brand new engine from Ford put in by a ford mechanic but now my rear end squeaks like crazy and it is all the time more so when going up or down a hill or when it's shifting more or less or going over a ruff surface that's been going on awhile and was told I needed a new rear end by the same ford mechanic and wanted 1,000 to fix it!
But also said the whining noise that is coming from the front was the transmission and that I shouldn't worry about it to drive it till it goes out but it's a terrible whining noise that you only hear it when your in gear not in park or neural the truck sounds good what causes this whining noise?? Not done yet but recently the front driver side around the wheel has also gotten a squeak mostly when in low speeds and turning to the left! What to do? I'm already replacing the motor! Hopefully these are some easy fixes! I've done some research and the whining from the front that I was told to be the transmission doesn't seem to be that I would think more along the lines of pulley or alt!

I have a 2006 f150 it was making a knocking noise after the engine oil temp reached 160* and made the noise to 1700rpms. I thought it was the cam phasers so I replaced them. The truck is still making the noise and running rough and stalling but not as bad and not as often. Before it did it all of the time. The truck is timed properly. I had a new cam sensor and tried it but that did not work. I watched vct on the scan tool and both cams are in sycn.

I am working on a customers 08 F-350 5.4l has 135k on it. came in with a severe rattle/knock, running poorly, and dying at stops. ECM gave up 8 codes relating to the timing... Found the phaser replacement steps here on FTE and followed them and replaced the VCT solenoids since i was in there. Customer reported that he replaced the cam sensors already. Ran great for a day, and the next day when I pulled into the shop it gave me a rattle. Not as violent as before but noticeable. I special ordered the wedge and followed the replacement to a 'T'. I have no performance issues and no codes.

I just started to have this problem yesterday. Engine light comes on and stays on. Engine shakes and truck won't go over 50 MPH. Autozone code checker came up with P0171.
Truck has about 95K miles and I had the spark plugs replaced at 75K miles.
Transmission was rebuilt at around that time also.
I only drove it to Autozone and back today to post the code and see what everyone's opinion is as to what's wrong.
Here's what the printout says : P0171 "Fuel Trim Bank One Condition"
