Ford F-150 (2004-2008) :: 2006 V8 - Rough Idle / Black Smoke From Rear End
Dec 19, 2016
I just bought a used 2006 Ford F-150 it has the Triton 4.6L V8. Seems to be running ok a little white smoke on start up, but the other night after leaving work at 5am when it was around 10 degrease freezing. When I started my truck it was idling very rough like it was about to die but it didn't after it warmed up it was a little better but I think I seen black smoke from the rear end, but like I said after it was warm it sounded like normal so I started to head home and got about 15 mins down the road and it started to run very bad like it was bogging down and lost all power if I pushed on the gas all the way I was not picking up any speed but if I let off the gas the truck would jerk very bad and gain speed. But the next day in the morning it started up fine no problem I even drove it around town with no issue. What this issue could be?

so i bought this truck about 3 months ago and it was running real bad when i got it, I went ahead and changed the lower and upper intake gaskets, cleaned throttle body, egr ports on lower and upper intake, did timing chain cover gaskets and 3 bad injectors i found while doing gaskets, truck ran better but still black smoking(running rich) and getting 8 mpg. So I changed fan clutch,fuel pump fuel filter,airfilter,MAF sensor(old one was pulling 14.4 volt), DPFE sensor and all 4 oxygen sensors(old ones carboned up and real sooty).
I've checked my egr valve while idling and when it opens the engine just about stalls, truck seems to be running better but CEL light came on again and is throwing these CODES:
P0453 (evap emission ctrl sys pressure sensor high input),
P0141,
P0153,
P0135(oxy sensors),
P0401exhaust gas recirculation flow insuff detected,
P0460fuel tank level indicator circuit error.
And I believe I've told everything i know ...

I got my 2.0 turbo project up and running. no CEL but i did have a bad o2 code but it was erased and didn't come back.
Not only is it rough idle and smoking out the exhaust but i am also getting smoke out of my catch can vent.
The smoke looks black coming out of the tailpipe but little blue after it gets out a ways from the car. Where to look??
I did just replace a piston and install a head gasket spacer. I don't know if that could be causing it some and it will go away with some driving or what?
I have not taken it out on the road as I have some brake work to finish. so mostly it idled.
Here is a link to a video on what the car is doing : [URL] .....
Its a 01 engine code....

I just bought a 2002 v10 crew cab, everything great form the first 3 months, but then my coolant sensor stopped working, changed it, and the same thing! Only works a couple of times, and the truck started to rough idle a little, and now I have black smoke coming out of the exhaust!

05 6.0 deleted and studded. 170k fresh filters and oil, no CEL or codes.
This has happened 3x in months, so it intermittent. Truck will start fine cold, except for this last episode ....
Truck starts right up, idles correctly, speed bumps up if its cold enough to trigger the high idle. About mid way through its warm up, at approx 130-140 idle falls off, barely runs. Almost knocking. Black smoke if you give it throttle. Has no power when its doing this. Truck will not move and almost dies in gear. Give it til 185ish degrees then pooof! All good.
However 2 days ago it wouldn't start. Cranks but won't catch. Stumbles and dies. Finally got it to start after setting the charger on it. I killed it. But this time when it started it was straight into its rough idle, no power...until about 180. I switched it off, restarted it and it was totally fine
Ficm is 47-47.5. Every now and then I see a 46.5 for a split sec
Hpop is 700-800cold cranking.
Not sure what else to look at.
Moto craft filters.
Amsoil 5w-40
Archoil in the fuel and oil
Twc3 at every fill up.

I have a 2004 f250 i purchased a month ago. Its been cold in Denver this last month which is why I didn't mind it much. But now that its been in the 70s im concerned. Its always the first start up that it acts up. I go to turn the truck on and it starts idling for only a sec or two, then shuts off. I crank it about 3-4 times before it actually comes on and stays on. There is black smoke not white smoke once it starts to idle. Once idling it stays on and drives the way it should. If i try to start the truck again it will do so with out hesitation. I just did a tune up at grease monkey including fuel filters and oil filter. again its the first start up always.

I have a 2006 f150 I just bought after my F250 was stolen. It has about 70k miles. It has been running pretty rough ever since I got it. It finally threw codes so I tried to address all the issues. Changed out a couple coils and all the plugs (motorcraft platinum). The camshaft sensor was also bad. Truck runs much better but still has an idle issue I cant seem to nail down.
I assume its something to do with air intake. It doesnt happen all the time. It runs rough and knocks and sometimes dies. If I give it gas it stops. I read it could be the idle air intake valve, but then I read that this model doesnt have one. I also read that air intake issues dont normally throw codes. Are there any common problems I could look for? Would cleaning the throttle body do any good?
I know the basics, but this kind of thing is tough for me to troubleshoot. You may have already seen me post this problem, but I didnt get much response so I thought I'd try one last time.

I just received a 06 F150xl with a 5.4 triton and idles rough with the following codes! p0357 p0012 p0340 p0344 p0351 p0352 p0356 p0358 p0357 p0102 p0113 p0353 p0354 p0355 It's amazing the truck even runs and with no light on but it will accelerate. someone mentioned to clear the codes and drive it 50miles or so and read them again.

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.

I just bought an 2006 f150 4x4 with a 5.4l 3valve, and this morning when I pulled into work it was idling Rough as I let off the gas and rolled into my parking spot. No check engine light or nothing, just when it's in gear Rpm is at 600-700 and vibrating. When I shifted it into neutral or park it went away and the engine ran smooth. According to the oil pressure gauge I've got good flow. I was told from the dealer that they replaced the cam phasers, timing chain and put new spark plugs in it. What the issue is here?

Ok new issue that started yesterday only get it at idle. Runs great above idle no real power loss or change in fuel econ. Haven't really had a chance to test much. I was thinking maybe a injector issue but I don't know

So I have had the car for about 6 months and on occasion I have noticed faint black smoke at start up. It usually goes away after the initial start up.
The car did get the recall or TSB on the engine valve ring issue? Not sure if that's related or not.
Also it has an aftermarket cat back Tanabe exhaust if that's relevant.

completely stock 2006 4.6, 230,000 miles, I purchased and can vouch for everything after 106,000.
Two separate issues...have had a slight ticking noise growing for about the last two years. Seems to get slightly worse near an oil change but that could be my imagination. It has finally gotten loud enough that my wife (who drives with the delicacy and observational skills of a Sherman tank driver) actually mentioned it to me the other day. It is directly related to engine speed whether the truck is in gear or not. I kind of think it might be a manifold gasket going out but am not sure. Am not very worried about it but...felt like I needed to mention it because of my bigger problem....
Truck has gotten very "cranky" on startup in the last week. Has a rough time finding an idle speed but typically sorts itself out after about 5-10 seconds. This afternoon it started idling rough at a stoplight. It got steadily worse and noticeable even at speed. Four stoplights and nine miles later it threw a code and coincidentally, I was in front of an Advance Auto. They read it and said the #3 cylinder was not firing. I bought an ignition coil, drove 15 miles home and changed it. From everywhere I looked online, this is the second cylinder from the firewall on the passenger side.
Had a little trouble getting it in and am not entirely sure it is fully seated in the slot, but I can't get it to go any further. Seems as tight as a couple of the others. I disconnected the battery to clear the codes, cranked it up and it seems to run "better", but still has a rough idle. Just test drove it about 12 miles and no check engine light but the idle has not cleared up. I think coil must be working fine because I have no issues at highway speed. Earlier, when I backed off the gas you would feel the miss very badly, but not as much when under a load.

I recently bought a 2006 that idles rough, not real bad, but bad enough for me (and my 9 year old kid!) to notice. I asked the dealer where I bought it and they put it on the computer and said everything checked out. He said "it's a characteristic of this motor." I've never heard of such a thing. The truck has 27,000 miles on it and the dealer flushed the fuel system. He said the throttle plate had a lot of carbon on it, but it still idles rough... 4.6 idle rough?

Have an 06 F150 5.4 3v with no power. spark knock. rough idle. wants to die while driving, and random misfire code. Have replaced fuel pump, filter, coils and plugs. What to check next? Already thought of EGR - it doesn't have one.

I recently purchased my first Ford pickup. I bought a 2006 F-150 with the 5.4L 3V engine. I have only driven it for about 300 miles so far and am having problems. The engine has 146,000 miles on it. I have read several posts on here about the cam phasers which I believe that I may have some issues with. The engine will run well when cold, on the road, etc. The engine does have a slight ticking after it warms up (cam phasers?). When I come to a stop after the engine is operating temperature, the engine will start to miss and shudder and all 4 above codes come active and are also pending (8 codes in total).
All 4 codes are logged at the same time. I have replaced both cam position sensors, both sensor ends and terminals for cam position sensors, checked wiring around the rear of engine (does not appear to be rubbed through), all plugs were replaced, and all COP boots are good. Is there anything that can cause these codes that may not be the actual cam position sensors, ie. VTC, COPs, cam phasers? What pins the cam position sensors come on the ECU (so I can ohm the entire wire harness)?
Also, if the engine is missing with the codes active and I rev the engine up it will come back to idle and run great. The engine never dies out, just runs horribly. I have also unplugged each sensor with the engine running which has no effect on the way it runs.

2004 f250 6.0, 173k miles. I just had the head studs done and a new head due to a crack in one head, I got it back 3 days ago and she was running great. I towed my landscape trailer yesterday full of mulch and only went about 5 miles with the load, after the job driving to another one I noticed it sounded like it was missing at idle with a small amount of white smoke. Drove it home let it sit overnight, started it up this morning and a cloud of white/ blue smoke and a horrible rough idle. Smoke does not stop.

1993 3.0 .... My son's van. He complained of fluctuating and mostly high idle, black smoke from exhaust and stalling at stoplights. He has other wheels so I've had it for several months until I could check it.
I started it every few weeks, it started easily. Have not seen smoke but it did idle high and rough. Yesterday I started it to warm it up to finally pull codes. Temp needle barely moved and upper radiator hose did not get very warm but I pulled codes with engine off anyway and got 116, 10, 111.
Today i got a little smarter and noted that the upper hose began to get warm right after startup. Suspecting a bad thermostat I blocked the radiator as well as I could and it warmed up much more, though still not near the middle of the temp gauge. Shut engine off and pulled codes again and this time got 111,10, 111.
With engine running, got 6, only-- and there's no code 6 in the code reader book. Jabbing gas pedal in neutral it nearly dies, jabbing gas in D and it dies and will not restart until cooled down.
Finally, checked again with engine off and got 111, 10, 110, 10. I think the ETC is OK since I didn't get 116 again but it still idles fast, speeds up and down erratically, and dies. Where do I go from here?

2002 Ford Ranger edge 3.0 flex ... Truck was running fine and giving me no issues. I woke for work the other day and went to get coffee and truck wouldnt start. I could hear fuel pump running and knew it wasnt that, it was acting flooded. So today I pulled fuse from fuel pump relay, and got it to start. Put the fuse back in and ran to gas station. On the way to the gas station it started running really rough, very low and rough idle, trying to stall out. I noticed it had black smoke coming from exhaust. I got it home, and got it to start barely, and it has the same very low and rough idle, but my oil gauge was going crazy, flickering back and forth all crazy, and the idol is terribly rough and eventually stalls out. Earlier today I did put new spark plugs in it, but not sure that has anything to do with the issue. I also hooked it up to a computer and it isnt throwing any codes.

I have recently been getting black smoke out my tailpipes on my 1995 F350 with 7.5L at certain idles and my check engine lights comes on and off, could this be caused from my O2 sensors going bad because of my gutted cats? It seems to be running rich and my idle is way low and at the point to shutting off, prob cuz of overload of fuel...
