Ford F-150 (2004-2008) :: Knock Sensors Replaced Now Won't Idle
I replaced my knock sensors on 2004 5.4L and now it will not idle without me keeping foot on gas. Idles down to +- 450-500 rpms. If I hold down gas pedla seems to run smooth. What to check to fix this problem?

2005 f150 5.4.
I have a slightly rough idle and can feel a miss at 1600 to 2000 RPM. Sometimes running about 65 MPH up a slight grade I can slowly press the gas pedal and the engine will begin to miss much worse, causing the truck to shake pretty bad. When it gets this bad it will slowly flash the CEL and I get a P0306 code (Cyl 6 missfire).
The truck has 148000 Miles on it and the plugs were replaced at approx 120000 by the dealer.
In the last week I have replaced the plug in cylinder 6 (looked ok) and have replaced all the COP's along with the fuel filter and the injector on #6.
I haven't been able to get it flash the CEL light or throw a code since replacing the COPs though and I am at a loss at to what to try next.
Prius (2004-09) :: TPMS Sensors Needed To Be Replaced
The dealer tells me my batteries in my low tire sensors are bad. The low tire light on the dash won't go out. So I need to replace the TPMS sensors in my '06 type 5 Prius. I know I can pick them online much cheaper than at the dealer. My question is, is there some reprogramming that will need to be done. I'm assuming it will be some convoluted sequence with buttons on the dash similar to turning off the backup alarm, etc.

My truck starts to miss between forty and fifty mph. When you get on the gas pedal it won't do it but when you are slowly increasing speed it will start missing or maybe you can describe it as bucking. Above fifty and below the truck runs fine.

I've got a no crank issue this morning. This truck has done this randomly off and on, mainly during colder temps, but normally if I hold the key in the start position for a few seconds it will crank. This morning, no such luck. Batteries are good, everything has power, I can hear the starter relay clicking when I turn the key to start but it won't turn over. It never does this during warm weather. It got down in the low 40s last night and it's rearing it's ugly head this morning. The only code is the P0341, camshaft position sensor, but I don't know if that would be the cause of this or not. It's a starter issue or the CPS?

View 3 RepliesFord 6.0L Power Stroke Diesel :: Randomly Shut Off When Pulling Into The Driveway - P0341 Code
A Little Background, my FICM wasn't bad per se but it would dip below 45 volts when the outside temp was around freezing. I pulled it and sent it for repair at the same time the Atlas 40 tune was loaded into the FICM.
First few days of driving mileage was better, truck ran great. All of a sudden one day pulling into the driveway it randomly shutoff. Two occasions since it has acted goofy at started, bucking a little a low throttle. Mileage has returned to how it was before I had the FICM fixed and ATLAS tune applied. To this point I had no codes at all.
Now today it randomly throws P0341 - Camshaft sensor out of range.
So heres the question - do I replace the sensor or try to get at the harness for inspection? Out of range would usually mean the sensor itself is failing while open circuit is usually wiring related. I know its uncommon for this particular sensor to fail but i'm not sure which direction to go.
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 1 RepliesFord F-150 (2004-2008) :: Slight Miss After Truck Is Up To Operating Temperature
I have a 2004 f150 with 135000 miles. Bought it a few months ago. I notice after the truck is up to operating temperature it seems to have a slight miss, you can kind of feel it when sitting in the truck. Cant really hear it. Outside the truck I am hearing a ticking sound. I have changed the spark plugs on the passenger side, because that's where the ticking sound was coming from.
Come to find out the last spark plug in the back was finger loose. Got them changed, on that side. Still have the miss after warmed up along with the ticking. Few weeks fast forward I put all 8 new COP on. Same results. I also have changed the oil and filter both with Motorcraft. Where I could look? I also have a 1 year unlimited mile power-train warranty.
Ford F-150 (2004-2008) :: 2006 - Cylinder Misfire And Random Miss On Startup
We've got a 2006 F150 with a 5.4 in it. One of the new kids was told to change the spark plugs, then when I went to start the truck the next day it was missing bad. Plugged in the Ford IDS, number 7 cylinder is dead. Only codes are for that cylinder misfire, and random miss on startup. So, I double checked the kids work and it was all fine. Tried putting a new plug in, didn't work. Moved the coil to a different cylinder to see if the miss would jump, stayed on number 7.
Used a noid light to verify COP harness was working, and it was. Put a new coil on it anyway since I had one, still missing. Used noid light to verify signal going to injector for the cylinder. Signal was good, replaced the injector for the cylinder. Still misfiring. Ran a compression test and the cylinder has good compression. The threads for the plug are fine, not cross threaded or torn out. The only thing I can think is that the PCM has gone bad in a way that its firing the injector/COP, but doing so at the wrong time some how.
Every other cylinder is running fine, O2 sensors fine. PCM isn't trimming anything back to account for anything, and if it was it would do it to multiple cylinders to keep the engine balanced. Cant think of any more tests, and I don't believe there is anyway that the airflow could be restricted to only 1 cylinder, but I could be wrong. Wanna try and solve this to keep from sending it to the dealer.
Ford F-150 (2004-2008) :: Truck Started To Develop A Miss - Multiple Codes
Apparently yesterday (no known reason) my sons truck started to develop a miss (so it feels like to me).
2005 f150 5.4 auto 215000km 4x4 stx. No specific cylinder codes. All general codes.
P1000
P1464
P1550
P1703
P1780
None of which I can see causing the miss. No check engine lite, no other codes. Not sure what to look at next. I am starting to disconnect the coil packs one at a time and see if I can pin down the cylinder.
Ford F-150 (2004-2008) :: 2006 5.4L Idling Very Rough And Had A Terrible Miss Around 1200 RPM
I have a 2005 5.4 F-150. First off it came to me on a rollback because the owner tried to replace his plugs after he noticed it missing and of course broke one off. So after I extracted the plug from #8 cylinder and installed a new plug I cranked the truck and it was idling very rough and had a terrible miss around 1200rpm. I pulled the codes and got several misfire codes and ignition coil faults on #5,6 and 7 cylinder. Popped in 3 known good coils in these 3 cylinders with no difference.
On Mode 6 on my diagnostic software you could watch the misfire count steadily increase on #7 and every now and then there would be a single misfire on #5 and 6. It also had several codes for O2 sensors biased, stuck rich on that bank. Well since it had a brand new plug and coil, I popped an injector in #7 and havent had a single misfire on it since and it also started idling alot better and all the O2 codes went away. The problem I am having now is #5, 6 and now 8 will randomly misfire, sometimes build up a steady count on one of them, sometimes just skip around between them.
The truck has brand new plugs in all 8 and new coils on this bank also. The truck has 115,000 on it and does have some cam phaser noise on the bank causing the problem, but its not too terribly bad, I have heard alot worse. My problem is something on that bank only as the passenger side bank is fine. I am wanting to say cam phaser now since this is the side with the noise. I have changed them before but have just experienced the noise, never one running like this because of it. Possibly jumped time a little?

View 9 RepliesFord F-150 (2004-2008) :: Engine Vibration / Miss At Idle - Slight Hesitation During Acceleration
I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.
Santa Fe (CM - 2007-12) :: Misfires Along With Error Code P0341 / P2189
I have a 2008 model 2.7 v6 with 80000 Km, and I would like to share my experience with several issues:
- Random misfire: brought the car to Hyundai, very bad response. I bought online the wiring of the spark plugs (according to them that was the reason of the misfire) and they installed it, did not improve. The car was still showing error code after clearing, and the fuel consumption at an average of 23L/100km.
- I then decided to change all the 6 spark plugs, no difference. The workshop told me the coils were in perfect condition. Still having a message like this: "ignition error on 2 or more spark plugs".
- I did a complete cleaning with contact spray of the MAF sensor.
- I bought online a couple of ignition coils, being original Hyundai ones, and changed them. When installing them i realized the existing ones were not original Hyundai and had a small marking, making me think they were recycled or chinese stuff.
- Having done that, the OBDII shown two more error codes: P341: error on camshaft position sensor, P2189: fuel idle (too much air, maybe caused by the first one). Changed both camshaft position sensors and then big change in the behaviour, more response, throttle, better gear switching.
- I so concluded that the 4 remaining coils have to be changed and ordered another time 4 of them online. OBDII showing now only one error code: random misfire. The engine going much better than all i got before.
- I have decided to take advantage of this order and also ordered a new TPS (seeing here that it was a common problem) and a Crankshaft position sensor (in order to prevent any other issue).
- I also changed previously 2 downstream o2 sensors that were giving an error related to emission. Emission here are not strictly controled so it is not a big issue.
My question is, what in all that sensors can more likely make my car burn 23L/100km??? Asian cities are quite similar to american cities, lots of highways. This consumption compared to what you describe is way over the normal one isn't it? I was assuming the ignition problem was the responsible, am i right?
Ford F-150 (2004-2008) :: Slight Miss / Hesitation - Power Loss When Driving Constant At 25 - 30 MPH Occasionally
Had this truck a few years now, and it has always had a slight miss/hesitation and maybe a few codes. The timing chain skipped a tooth and the truck was down for about a year. I have 4 other trucks, so it wasn't a big deal. I finally had time to put a new oil pump, chains, guides, tensioners, phasers etc. The truck actually runs very well and quiet. But, now misses far more than I remember it doing.
When driving in town constant at 25-30 mph occasionally it will loose power for a brief moment(<1 second) and then be fine, the security light on the dash turns on for a few seconds. It drives at 55-65 just fine, unless I am going up a hill or something else increasing the load.
2004 5.4 3v 2wd
CEL-
P0453 (fuel tank pressure issue)
P0351 (ignition coil a primary/secondary circuit malfunction)
P0356 (ignition coil f primary/secondary circuit malfunction)
The coil packs are new, and I have injectors on order. Also found this thing on the back of the motor, it connects to the fuel rail on the drivers side. Where it should go. I looked on my other trucks. But my other 04-4wd has a box by the battery it connects to, but mine doesn't have any of that stuff. And my 08 doesn't have anything like this at all.
And a pix of the truck in question.
