Ford F-150 (2004-2008) :: 2007 - Check Engine Light At 59,000 Miles
I've got a check engine light on but the truck runs fine. I checked the fluid levels everything seemed normal. Any special trick that I could try to reset this check engine light myself? It's got the 4.6 L, Stock no mods, been keeping the regular service intervals at the dealership.

I have a 2005 f-150 with the 5.4 engine. Bought it new and now it has 107,000 miles on it. Recently,it would have a shudder at 65 or 75 mph then the passing gear would kick on and it worked perfectly. The warning check engine light came on,then,when it acted up it would flash intermittently. Took it in to the dealership and put it on the diagnosis machine. Said cylinders 2,3, and seven were not steady etc?? So,after he took it out and drove it he said those particular cylinder walls were scored. I put in a K-N air filter at about 50,000 miles,and he said that they do not seal properly and dust got by the filter into the intake and got into the engine and did this damage. One think he found was a bad coil on one cylinder and replaced it. And just as he said,when I got on the road home I romped on it and it cut out and the intermittent signal showed again! He said that that would happen and it did.

So the check engine light came up on my truck and I scanned it to find P0021 which is Intake camshaft over advance or VCT solenoid stuck open. I really doubt my truck skipped timing and all the research I've found had it linked with other codes requiring cam phasers. The truck is a 2008 F150XL with the 5.4 Triton with 90k on it

I was driving when the truck made a terrible noise and while pulling over the check engine light went on as well as low oil pressure. I turned off truck and checked but no evidence of any leakage at all. Checked oil stick and was dry. Let sit for an hour and checked oil stick to find about 1/2" showing. Added oil to find that now it was overfull, drained oil back and stick showed proper level. Attempted to drive and it was fine until I came to a stop wherein it would stall with "low oil pressure" showing and check engine light on. Brought to shop and they said engine is very gunked up, they said they could try oil flush but probably will not work. They most likely will have to remove the valve cover and such to physically look at engine and take it from there... (I have always used type of oil stated on the cap, used synthetic and changed every 5-7k miles - showed diagnostic codes p0011, p0340, p0345 and p0021).

I bought 04 Lariat (5.4 3v around 100k miles, Roush Off Road side exit exhaust, DWV intake mod, SCT 3015 tuner).
The truck has had a miss on and off for around a month I've changed plugs and tested all the coils. Which cured the problem for around a week, the FPDM had some white stuff on back and soft spot but not ate through. The only Check Engine Lights have been bank 1 to lean (which went away as soon as it came. But yesterday and today I've got bank 2 to lean.
Below is a quick data log pull... The misses is about ready to ship her out if she don't straighten up..
Ford F-150 (2004-2008) :: 2005 - Check Engine Light Came On - Cylinder 5 Misfire
I have a 2005 f150 with 96,000 miles. Long story short, last August I was headed to the mountains going up a steep long hill and the engine light come on. once i was over the pass the light went off. During my 4 wheelin' trip it never came back on until I was headed home and going over another pass and then it stayed on for a couple of days. I had it checked and it was a cylinder 5 misfire. I did some research and found that replacing the coil cover might fix the problem and if not the spark plugs would need to be changed.
I changed the coil cover, problems solved... until I headed to the mountains. light came on and then eventually went off later that day. I didnt think much of it. then a few months later i was headed to the mountains again and the light came on in the same place on the steep incline hill. I. took it back to the shop, same reading. I decided it was time to replace the spark plugs anyways so I would invest. I have new plugs and everything is good however, I had no plans to go to the mountains in the near future. Now, a few months later I headed to the mountains and crossed my fingers it would not come on but it did.
I've done the research again and it seemed like the coil cover and spark plugs are usually the cause of the problem...however I have changed mine. The light is now off again. I don't understand what is triggering the problem and what is really happening and if it is safe to keep taking to the mountains with this happening. I did notice that everything was fine at 60MPH but once i hit the hill and steeped on the gas to go 65 and hit 4-5RMP that is when the check engine light came on...
Ford F-150 (2004-2008) :: Lost Power And Check Engine Light When Putting Pedal Down?
I went for a drive in my new truck and hadn't put the pedal down until now. its really cold here (5f, or -15c). Anyways so i waited for the engine to get warm and then i put my foot down until i got to about 100km (60 mph). Everything was fine, I was on a gravel road so i turned around and did it again, this time i totally lost power once i hit around 60kmh. the check engine light flashed a few times, i tried again, same thing, this time the check engine light came on and stayed on.
I eased off the gas a bit, then came to a full stop a little ways down the road. I tried again and this time i had full power, though i didn't take it to 100kms because there were icy patches all over the road and the truck went a little sidways. The check engine light was off, and i tried one more time after that and got up to 100 and everything was fine and the check engine light never came back.
I'm worried, my first real truck here, what happened?? Also when i stopped the truck i had a listen to the engine, everything seemed normal, but I've noticed before there seems to be a clacking sound almost, not sure if this is normal with a 5.4? I had a 2.2 litre sonoma before this so I'm new to all this.
Ford F-150 (2004-2008) :: Check Engine Light Code Says Catalyst Deficiency Bank 2
I have a 2006 F-150 with the 5.4L. I got the check engine light and the computer says catalyst deficiency bank 2. So I assume the passenger side converter is blocked. Is there anyway to either take out the cat and replace with a piece of straight pipe and bypass the o2 sensors or take the cat out of the housing and put the housing in and then bypass the o2 sensors.

I have a 2008 FX2 5.4L F150. Recently it began to lose power on a friend driving it out of town. He got a check engine light then it just progressively became unable to produce power. It ran but he got down to 10 mph before he could get to a firestone. I got it to a local Ford dealer and they say i need a new engine. They gave me codes for cam sensor and timing and #5 and #6 misfire. (344, 345)
No oil in radiator, no water in oil. The crazy thing is it runs like the day i bought it in Park. But once in gear it begins to cough and then eventually shudders and dies. I haven't changed plugs ever. I know... At about 75 miles it began to idle rough at times and in reverse. But once I revved up it went away.
I replaced both cam sensors but no luck. Today i put it on a tow truck to get a second opinion from a local engine shop. I actually backed it down my driveway, and pulled up to the tow truck with no issues. weird...
Ford F-150 (2004-2008) :: 2006 - Check Engine Light Started Flashing As Accelerated Uphill
2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00
MIL Status Off
Troub Code P0174
Abslt TPS 24.3%
Eng speed 1665
Baro PRS 71 kpa

Ford F-150 (2004-2008) :: Stumbling / Running Rough - Check Engine Light Is Either On Steady Or Flashing
Got an 07 Screw with only 50,000 miles. Yesterday, wife drove it home from work and said it would only do 45mph and didn't sound good. No warning lights were on, she said. I test drove it in the evening and it ran totally fine. Today, she drives it to work and said it ran real rough and "Check Engine" light was on. I picked it up from her work and it idles very rough and slow, and once you hit about 2000 rpm, it runs decent, maybe even normal. Below that, it stumbles and engine doesn't sound right. "Check Engine" light is either ON steady, or flashing. I don't have a code reader, so its likely going to the Ford Dealer Monday. Is there any way to read the code without a reader?

2005 F-150 4.6L 2WD, 268,000 miles....
Recently I got a flashing 'Check Engine' light and a rough running engine (along with a tapping noise) when I was passing someone (and pulling a trailer). I retrieved codes 300, 304, & 305. I can't swear to it, but I think the tapping noise started at the same time as the coil problem.
I replaced coils #4 & #5 (later that same day) and the engine smoothed back out but the tapping noise is still hanging around. The noise speeds up at higher RPM's and doesn't go away if I shift into neutral. Oil level and pressure are fine and I only use Motorcraft 5W-20 and Motorcraft filters (and change the oil every 5K miles).
Not sure if this is relevant: I think I have bad valve guide seals (blue smoke after long idles) but no other problems that I am aware of. It sort of sounds like a lifter, but is there a good way to pin it down? Is it possible that this tapping is related to the bad coils?
Ford F-150 (2004-2008) :: 2005 - Check Engine Light Code P0420 - CAT Threshold Level
Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. so I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work and worked in a shop in high school. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?

I have an 05 F-150 Lariat 5.4 and it has been going haywire today. While driving if I hit a hard bump the power will cut off (radio, a/c) and even sometimes the truck. Check engine light came on and I pulled codes P2160 & P0506. Also, when it completely cuts off and I start it back up it says "engine in failsafe mode".

I have a 2006 F150 4x4 5.4. For a long time it idled poorly and would take 2 trys to start. Today it started shuddering and the engine light came on. The engine light went off but it still runs rough and smells of gas from the exhaust. It is not very drivable and I can't afford to take it in. I have lots of mechanical experience but not with this electronic junk and need diagnosing the problem. I have a code tester and this is what it said.

Prius (2004-09) :: 2008 - Right Faulty Head Light Triggers Check Engine Light?
I was wondering if this seems reasonable. I just bought a used 2008 Prius top trim package with 107,00 miles on it this last month. The first day I owned it a check engine light was triggered. The guy I bought it from hooked it up to his computer and cleared it to then try to trigger it again. This happened when I first turned on the car. I started backing and then it turned on. I didn't know what caused it as we couldn't trigger the response again. It's been a few weeks now and 1 trip to the shop for some repairs. There have been no problems what-so-ever since then and my Prius just started getting close to the 50 MPH as advertised after a tune up.
Today when I'm driving, as the seller did mention before could happen, the right headlight turned off. As he had told me before, just turning the lights off and turning them back on will get it working again. I did this and as soon as I did the check engine light came on. I go back to the night I originally had it happen and I was probably in the process of turning on my lights.

I have a 2005 f-150 street boss with 79000 mile, and it is shooting off going down the road, and the check engine light is flashing. The first time I started it back up and it would idle fine, but the throttle wouldn't do any thing. After setting about 15 min. I started it up and it ran good. I checked the codes and it had a p2104 Throttle actuator control system forced idle. It happened again with my wife. This time when I checked the codes it had the p2104 and a p2112 throttle actuator control system stuck closed code. What could be the problem, or a troubleshooting guide I could use to try and diagnose it.
