Ford F-150 (2004-2008) :: Engine Starts To Run Rough And CEL On Within Seconds After Idle - Code P0351
2004 F150 5.4 3v. I bought the truck with 102k on it, it now has 124k. In the morning, when the outside temp is between 30-50, the engine starts and runs fine. When I get to the first red light ( about 1 mile away) within seconds of the engine at idle, engine starts to run rough and CEL. Every time the code is p0351. If I let it sit in the driveway to full warm up... no problem. If I start the truck, shut it off and restart...no problem. It only happens at the cooler temps. I have changed plugs, used motorcraft, nickel antiseize, torqued, etc. Ford changed the coil, I have changed the coil, cleaned MAF. As soon as I cross the intersection, light stays on, rough running clears up, and runs like a champ for the rest of the day.

The 2005 Avalon has 48K miles and it's been running well without any issues, until today.
Driving in city traffic, max speed is about 30 ml/h, The "Check Engine" light and the "VSC (Vehicle Slip Control) Off" lights came on. I did stop the engine, restarted after couple of minutes and the same lights stayed on. The car ran just fine, no noticeable difference in performance.
With the OBDCOM reader, the Avalon has this code:
P0351 232
P0351 Ignition coil A primary/secondary circuit malfunction
That seems to indicate a malfunction for cylinder A, or #1, ignition coil that has nothing to do with the "VSC" AFAIK. Is this a misread by OBDCOM reader, or the Avalon is confused?
The code had been reset via the OBDCOM reader, the car runs fine, neither of the lights come on now. Should I do something about coil A, or just wait until the code comes back?
Saturn - Vue :: OBD Code - Car Is Giving P0016 And P0017
The car is giving me P0016 and P0017 codes. I have read up on them, and it appears 17 could point to 16 being the culprit. Regular service, oil changes when the car says it is time. Vehicle has 90k miles. This is the 4 cyl engine. So, what am I most likely looking at? One or both sensors? Basically, is there a common problem associated with this vehicle and these codes that I can begin looking at?

My 2003 Expedition has begun to "stutter" when I am cruising around 35-50 MPH and not giving it much gas. If I am accelerating, or take it out of overdrive, it does much better. It is not an engine skip, more like a hesitation in the transmission. I recently had the transmission fluid changed.
View 4 RepliesFord F-150 - 1997-2003 :: 2003 - Got Code U1262 - Random Misfire?
I have a 03 F150 with a bi-fuel 5.4 engine an it has 195000 miles. I have had trouble for some time now with misfires. I bought the truck in october of 2011 with 125000 miles and replaced all the coils and spark plugs because it was misfiring badly will running on CNG. It was fine on gasoline and never had any codes. After I replaced the plugs and coils it ran fine on CNG and gasoline.
This summer 2013 it began missing badly at highway speeds only when running on CNG. If I accelerated the miss would go away until I was light on the throttle again.I checked the misfire count and found the bad cylinder and replaced a coil. Then a day later same thing on another cylinder. I swapped a coil from another cylinder and problem went away for a day. Eventually I chased the misfire around all the cylinders on the engine until I had ended up either replacing a spark plug or swapping a coil on all the cylinders. And I still had a misfire. It seemed to be worse on days with temperatures above 90 degrees. Eventually I got it to stop misfiring.
So now 5 months later I am back again with a misfire. This time it is misfiring on both gasoline and CNG and under any throttle conditions, except coasting. I have no codes. And the misfire monitor is sending me around the engine again. I have replaced a spark plug in two cylinders and swapped 4 coils.
I'm ready to buy all new coils, but I want to be sure that it is not a waste of money since the old ones only have 70000 miles on them.
Two days ago I had the misfire monitor saying #4 in the evening and the next day without me having done any work on it it was saying #6. Later that same day it said #7 and I still hadn't done anything other than drive the truck.
I checked the connections at the firewall on the drivers side with the three large plugs that are held in with a 10mm bolt, they looked fine, no corrosion or burnt pins. I checked the connection at the ACFM which also looks good. I will check the connection at the PCM in the next day or so.
Some other problems that may be contributing:
1. I occasionally get a U1262 code (scp fault)
2. Sometimes when I check the misfire monitor it only shows 7 cylinders, sometime 9 cylinders. I am using an Innova 3160 scanner.
3. I have either a leaking valve cover gasket or leaking head gasket, because I have oil dripping from the rear bottom corner of the passenger side cylinder head right above the exhaust pipe.
Ford F-150 (2004-2008) :: Miss At Idle - Got Codes P0351 / 356?
I bought a 04 FX-4 a couple months ago with 102k on it. Brought it back to selling dealer, they replaced #1/#6 coils, its ran great till this past week. Again it has stumbled a couple times this week. It only seems to have the miss at idle (comes and goes) take off from light, within 50 feet its running like a champ again. I cleared the codes (disconnect battery)and now it seems my idle is not steady, it fluctuates. Is the idle a product of the codes?
View 2 RepliesFord F-150 (2004-2008) :: Power Shuts Off For Two Of Injectors / P0351 And P0356
2004 f150 5.4
When I start the truck it runs fine for roughly ten seconds then it shuts off power to two of my injectors. Or so I thought. With a noid light on, I was getting shutdown on cylinders 1 and 6 as per the codes ten seconds after starting. I assumed this was as intended to stop raw fuel from entering the cats.
So far this is my findings. Noid light-shuts off the two cylinders after ten seconds. But will pulse again later before shutting them down again. Truck idles better, but never seems quite perfect. Could just be how 5.4's are though.
Swapping injectors did not change codes.
Coil packs are working on those cylinders. Spark test checked out and plugs are firing. They were replaced at some point with oem motorcraft plugs.
ohm test showed wiring to those cylinders was fine. Wiggle test showed the same.
The truck revs and sounds great before it shuts off power to the cylinders. I cannot assume a mechanical failure at this point. I have not ran a compression test on it yet as, in their great wisdom, Ford determined they had to be different than the rest of the planet with spark plug sizing. Adapter will be here tomorrow for me to verify that part.
I have checked around quite a bit so maybe this has been somewhere else on the site and I missed it. I have exhausted everything minus a compression test. I can only point a finger at the computer currently. But I am not quite sure how to verify that is the issue. And quite frankly, I have never seen a computer go bad without outside interference.
On a sidnote, the truck starts very hard at times. Like a car that has heavily advanced timing. It could actually just be a starter issue though. I figured I would get to that after I find out what the other issue is.

Had to put a new tranny in my 1997 F150 XLT Lariat 4x4 5.4 liter engine about 3 weeks ago and now have gotten the check engine light. Took it to autozone and code 1450 was the only code listed. They said it was was a vacuum problem, but when I checked the code at a web site it is listed as a secondary air injector system circuit shot to B+.
My question is which is correct and how to repair?

I changed out the hose from the intake to the canister purge valve on the firewall next to the master brake cylinder, that one was like dust.

Extremely rough at 40-45 mph. but with no misfire codes just p0171 so all 8 coils and plugs and sparks replaced twice in one month. and still same code tested fuel pump pressure 28 psi.... removed clogged cats, still same code... new pcv valve and elbow.... checked for air leaks around intake and intake manifold and nothing.... cleaned mass air flow sensor...I can unplug any coil on bank 1 and it wont make a difference. But if I unplug any bank 2 coils and engine makes a difference.
