I just had my check engine light come on and checked the codes and they were P1136 running rich at idle and P1250 low fuel level. My fuel level is 3/4 full and I just installed a K&N panel filter in the airbox. While I was installing the filter I also cleaned the mass airfow sensor and then cleared the codes. The codes have come back after 2 days.

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.

I am perfectly capable of doing the repairs just short on time. the only shop in town is booked out 2 weeks, i need my truck sooner. 2006 f150 5.4v 3v 168k. I bought it with 150k and it was clean and ford maintained from the original owner. for a while it has been fluttering from time to time during acceleration. last week it started shuttering and missing around 45 trying to accel. no cel. I've read and actually fixed my freinds 08 but replacing cop and plugs. I bought motorcraft plugs and granatelli coils. friday morning it didn't want to start, cranked for a bit then locked up, as if hydrolocked.
I let it sit 5 minutes then cranked again and it fired but hesitating and missing like never before. anything passed 3k rpm it ran good no load. i had to drive it and it doesnt want to shift properly, revving way past normal shift points. smoking alot more than normal. hard to tell being 5 degrees out. finally got some codes. bank 2 sensor 1 stuck rich 4 times lean twice. Saturday i changed the oil plugs. and coils plugs were not original but were worn enough to visually see. all of the passenger plugs were a nice brown color. all of the driver side were jet black of carbon which follows the o2 cel. i reset it with my glorifed code buddy and it took a while if at all to come back. so im thinking not an o2 sensor????
It runs rough and will stall from time to time, I am to the point where i wont drive it. i will be replacing the camshaft sensors and vct solenoids tonight, and that one 2 if i have time. from what I've read phazers will cause a rough idle but once under load at least have some performance. when i accel it the rpms stall out before a shift i cant get anymore power, say wont got over 3200rpm. when chains and guides need to be replaced whats the symptoms??
Ford F-150 (2004-2008) :: Codes For Misfire On Cylinders 4 And 5 And Coil D Circuit Malfunction
I do not know the 5.4l 3v as well as my last 360ci dodge. It's a 2005 F-150 SuperCrew 4x4, got it cheap, and it's got issues. Got codes for misfire on cylinders 4 and 5 and Coil 'D' circuit malfunction. Obviously it has codes for limited power as well. was wondering how cylinder numbering goes and what coil is 'D'.

The truck is a 2005 5.4 with ~130,000 on it and it runs very well for the most part. I have done the spark plugs before the summer and replaced them with the motorcrasft sp-515s. I am guessing the problem will be with the #4&5 coil packs. is there a way to troubleshoot these?
Ford F-150 (2004-2008) :: Misfire Codes / Engine Shuddering Under Acceleration When Cold
My new to me 04 4.6 shuddered and misfired really bad last week, got couple misfire codes. I changed plugs which were really bad, like burnt out to .080, got a HEI ignition tester and got a healthy spark from all the coil packs. Drove it today and ran much better but still would shudder under acceleration when cold, wasn't as bad when warmed up but still noticeable. I thought if I got a spark with the tester that means the coil is ok? or is that not the last word in coil health. Or should I look somewhere else like injectors ? Haven't got any codes since plug change.
View 1 RepliesFord F-150 (2004-2008) :: Rough Idle / P0012 - Misfire Codes Associated With Bank 1 And Cylinder 3
5.4 3v. my last few weeks have not made me a fan. Here are the details:
I bought a 2008 F150 XL 5.4 3v with a cam phaser knock. Have done other timing jobs in past with no trouble so I was not too afraid to tackle this one. famous last words...opened the motor (shout out to the passenger side valve cover and its designer here) and found semi damaged roller follower on driver side. Worn cam lobe on the corresponding lobe and a loose chain on passenger side. proceeded to :
Change all timing components: phasers, chains, tensioners crank sprocket, all applicable bolts and BOTH cams as well as all lash adjusters and roller followers. most looked fine in fact all really did with a bit of wear on a few roller followers but only one bad one. engine didn't look to bad pretty clean.
Double and triple checked my timing chains and it was spot on. dark link on spot on crank, two dark links on the L and R dead on. put it back together. oh yes, changed all plugs with motorcraft ones, didn't even break one. did not change vct solenoids because I falsely assumed I could change the later easily if needed. they looked ok. screens intact etc... silly me for not realizing how kind Ford was in 2007 and later to necessitate removal of valve cover. I was reading a previous one on the how tos and assumed later models would be the same since it was the same sensor...
Cranked truck ran great. I mean perfect. sounded perfect. ran like a scalded cat. till it got to hot idle then it started doing its thing. rattle shake till you revved it. ran fine just wouldn't hot idle fine especially in reverse or under slight load. replaced driver side vct since ford only had one and I started on the easy side ordered the other one waiting for it. seemed to improve dramatically meanwhile I am driving this truck to test it. I drove it to work 50 miles each way and it ran great.
After a few trips it popped the P0420 light, seemed to run ok, cleared it watched it wouldn't come back. O2 sensor did seem to imply a bad cat on bank 1 since it seemed sensor two was mimicking sensor one and not staying stead like the other bank. still ran fine,
So I decided to check back pressure on the cat. I pulled sensor one out of bank one (really a joyously tight squeeze in there) hooked up my gauge and got 0 back pressure. revved it and all nothing. hooked sensor back up pulled truck out of shop and it commenced to running like crap. I mean bad. running worse than before I got it. Popping P0012 code continuously, and tons of misfire codes associated with bank 1 ..cyl 3 etc.. I tried swapping coils, pulled coils and checked spark with a tester and firing away looks like tons of good spark.
Now the weird part is : looks like bank one is dead. I can unhook any coil pack and/or injector and it runs the same and sounds like it is missing. if I unhook one off of bank 2 it almost dies or does. so bank 2 seems to be running fine. it will start and run but sounds like it missing sets flashing check engine light and backfires and stalls like crazy. I even second guessed my pressure gauge and unhooked exhaust manifold from pipe and it sounds even prettier when it backfires out of there but no change. I pulled cam sensors and cleaned it again and even tried swapping them since they looked identical but no change so I put them back.
Now I can only surmise that I am out of time somehow? or I have a gremlin perhaps? I like working on cars (usually) but this one is getting old. how do I verify what is wrong. if it is timing related how do I verify that now definitively once my marks moved I really cant figure out how to tell if it is in time? Since it has all new parts and they all ran beautifully till now. could it possibly be the vct solenoid doing all this? I plan on changing it when it comes in but surely it cant cause this many problems.. I unhooked it no change, and it does it at a cold idle and any rpm. really runs worse at idle but bad at any rpm.
Ford F-150 (2004-2008) :: 2005 2WD - Misfire And Hard Jerk When Going Uphill - Codes P0300 And P0171
I have a 2005 F-150 5.4L 2WD 90K miles. I started getting a misfire and hard jerk when going uphill. No codes for a few days but misfire got a little worse and more jerking at full throttle acceleration or level throttle up a hill got codes p0300 and p0171. I replaced the fuel filter cleaned MAF and changed plugs Motorcraft plugs (none of them broke during replacement). Miss got worse. Missing at idle and no power 3K rmp to get to 40. Only code pulled was p0171. Replaced upstream O2 sensors and COPs. Will barely idle now. Dies when put in gear. Full throttle barely moves forward a few feet just sputters. Checked vacuum lines cannot find anything. Only code I get is P0171. Fuel injectors next? Or shop?

Prius (2004-09) :: Oil / Fuel In Intake Manifold - Misfire For All Cylinder And Reduce Engine Power Codes
I'm getting oil and fuel into the intake manifold every couple hundred miles. Oil level is in the middle of low and full mark. It's not like it's a huge amount of oil and fuel in the intake but it's enough to make the car misfire, bog out. Only codes I'm getting are misfire codes for all cylinder and reduce engine power code (forgot what code it actually is) but that's when the car completely shuts down and won't start with red triangle light. If I clean the intake out and unplug the battery for a few min I'm able to start the car again, but it will run really rough and white smoke will start to come out the exhaust (gas smell). I'm wondering if a bad maf would cause this. I've already cleaned it but still doing same thing. Don't really know what the specs or reading the bad is suppose to be so I'm kinda stuck to determined if I need a maf or not. Cars got about 242K miles.

Ford F-150 (2004-2008) :: 2007 4x4 5.4 Triton - Misfire Causing Overdrive To Act Up
I just bought a 2007 f150 4x4 5.4 triton with 69 thousand miles less than a month ago. Since then the transmission has been rebuild but come to find out a misfire will cause overdrive to act up, and it just recently started misfiring badly. It was throwing a code. 2 coils were replaced and still misfiring. It's not throwing a code anymore. No check engine light flashing or nothing.
View 1 RepliesFord F-150 (2009-2014) :: 2011 - Hesitation From Idle - Missing Or Running Lean / Rich During Spin Up Of RPMs
I have recently purchased a 2011 F150 Ext cab with 3.5L ecoboost with 69k miles. I have no experience with these engines prior to now. I've always wanted a full size truck and after driving my 98 S10 for 17 years, I decided it was time for a new truck. I hope I made the right choice in going for the 3.5 instead of 5.0.
On to my question. I've noticed that the truck hesitates from a dead stop or anytime the RPM's are under 1k. It feels like its missing or running lean/rich during the spin up of RPM's. When I drive it hard, it does seem to subside for a little, and I've heard people say that they run better when run hard. I can attest to that, but is this hesitation normal for an almost 70k mile engine? I am getting 15ish MPG on almost all city driving since I have bought it, but I do expect that to change (job hunting and current commute is less than 2 miles each way).
The only time I get to open it up is when I go run errands out of the immediate local area or visiting friends and family. On one of those trips, before I noticed the hesitation, I attempted to accelerate from 60 to pass on the expressway and it bucked and resisted like a horse. It finally took off up to 80 and completed that journey with no issue but the check engine light came on for a bit. The check engine light went off when I shut it down and hasn't come back on since.

Ford F-150 (2004-2008) :: 2007 - Bucking And Kicking / Misfire On Left Bank
Truck has been taken care of, new Motorcraft plugs done 15,000 ago, never had any issues with truck until recently. Started bucking and kicking, threw CEL light, pulled codes. P0018, P0022, P0300, 305, 307 and 308. All of the misfires seem to be happening only on my left bank. I threw in a new camshaft position sensor just for the hell of it. This issue goes away and comes back intermittently. I drove it for a day and it did fine. Had power and then started it later to go home and it was misfiring, got to a stop light, cycled key and everything went back to normal. 2007 Ford F150 Lariat 5.4l Triton....116,000k....

Im trying to chase down an engine miss fire on a 2007 with the 5.4L. It only seems to miss under no-load conditions, such as at idle and on a downgrade while driving. Acceleration and under a load it runs fine. New Champion plugs were installed at 135,000 miles. The truck now has 150,000 miles and has only been miss firing for the last 1,000 miles or so. I pulled the connector off of the coils one at a time to try and figure out which cylinder/s were missing. I thought I found the problem ones and replaced two of the coils, but it ended up not fixing the issue. Ive tried spraying carb cleaner at and around the intake to check for leaks, but found none. I have a scanner, but the check engine light is not on, so its not much luck.
