Ford 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.
Ford 6.0L Power Stroke Diesel :: Fan Stays Engaged Until The Truck Hit Operating Temperature
I replaced my fan clutch... Not a bad job, did it a couple weeks ago. I don't drive the truck much, but took it out today for the second time in the two weeks since I replaced it. The fan stays engaged until the truck hit operating temperature it seems. Is that normal?

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.

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) :: 2005 Truck At Partial Throttle Will Shake When Going Up Slight Incline
.Here is a run down of my truck 05 5.4L Screw has 130K on it. Sometime when going up a slight incline the truck at partial throttle will shake very very little. if I put my foot into it the shake goes away and the truck response just fine. It only does this when going uphill on the freeway and on the streets here in Dallas that have slight inclines.
The truck is not throwing any codes nor does it stall at lights. Starts right up in the morning and runs good. Nothing done to the truck except I have an Edge programmer and Magnaflow exhaust. I have pulled the programmer off and returned the truck to stock and it still does the same thing.
I bought the truck used in 07 had 40K miles on it. I'm thinking spark plugs or maybe a coil is going bad. But this doesn't happen all the time just here and there.

I have received a code twice during really cold weather and I think it is P0125. This says that the cylinder head temp. sensor is recording too low of operating temperature. The question is two fold. What happens if you do not change it? Second I have read that you have to remove the whole intake manifold to replace it. Any easier way to replace it than removing the whole intake manifold? I have looked for the darn thing and can not even see where it is located.

My best friend has a 2011 Ford F-250 6.7 ltd power stroke diesel XL. He was driving to Denver in -4 degree weather when all of a sudden his windows iced up and the temperature gage would not sit at normal operating range. ( stayed all the way down on the cool side) the heater seemed to be blowing warm air not hot like it usually does. The thermostat was changed 2 months ago any thoughts on this one?
View 14 RepliesFord Ranger / B-Series :: 1997 - Engine Will Not Reach Proper Operating Temperature
I have a 97 Ranger 2.3 standard shift, No A/C, a pretty simple Ranger with 158,000 miles. About a month ago while do some checking around under the hood I noticed my coolant overflow tank was empty, so I filled it up to the proper level with some anti-freeze mixture. Thinking if the system was low on anti-freeze it would suck what it needed from the recovery tank, wrong! About two weeks ago I noticed that my temperature gauge was NOT registering in its normal position and was considerably lower towards the Cold mark. Heat coming out of the heater was normal.
I opened the radiator cap and everything looked okay. After a few days this would not go away and replaced the thermostat thinking the thermostat was stuck in the open position, wrong again! I burped the system by letting the engine run with the radiator cap off and filled the radiator with anti-freeze mixture every time some of the air was expelled. I did this for a few days and noticed that the engine would not reach normal operating temperature at idle speed! I had to put something on the gas pedal to increase idle speed so the engine would get hot, this is not normal. Finally I got to a point where the radiator would not take anymore anti-freeze mixture, but the problem still exists.
Two things I noticed that will get the engine temperature up to normal, engine speed (RPM's) and not having the heater on. Let me explain, at normal idle the engine will not reach its proper temperature, but when driving down the highway the temperature goes up to normal (about halfway on the scale) no matter if the heat is on or not. When stopped at a light or just idling I can watch the gauge slowly go down towards the cold mark, if I turn off the heater it takes longer to go down to cold. I do know the heater fan is cooling the coolant to a degree (no pun intended), but it shouldn't cool it so much as to make the temperature drop so dramatically. Okay, heater off, riding down the highway, everything normal, come to a stop and idle temperature starts falling slowly, but when I turn on the heater the temperature starts falling faster.
My diagnosis: I have no leaks of anti-freeze, checked and re-checked. I have no symptoms of a blown head gasket, no milky white appearance on dip stick indicating anti-freeze mixing with engine oil, no clouds of white smoke coming out of exhaust, checked tail pipe for anti-freeze, none found, no loss of power and no loss of gas mileage. I changed the thermostat, like I said. Do not think it could be the radiator pressure cap, normally if the cap goes bad the system will have no pressure and the engine will overheat, the opposite of the problem. Water pump, normally if the water pumps goes the coolant will not circulate through engine and will over heat, again, not the problem I am having. Could it be:
1. A long shot, I bought a defective thermostat and it is still staying open.
2. The temperature sending unit has gone bad, very improbable since it does register the correct temperature when truck is moving down the highway.
3. The coolant is spent, again unlikely, it has been in the engine only for about 3 years and still looks clean and green.
4. Have to have a cylinder pressure check to determine actually if the head gasket is really blown or not, which I doubt.
My conclusion is that I still have a huge air lock somewhere in the system and the engine is still not completely filled with coolant and when the rpm's drop not enough hot coolant is reaching the temperature gauge sending unit, but if that much coolant is not in the system, why am I still getting lots of heat blowing from the heater? The vehicles cooling system is not that complicated and there are few parts involved in its proper operation, I think I have covered them all, but somewhere I am missing something to pin point my problem.
Ford F-150 (2004-2008) :: Starts To Miss Between 49 And 50 MPH
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 have a 2000 F250, 300k. Starts beautifully when cold, takes 10 seconds of cranking when at Operating Temperature. Did the injectors and plugs in September, kept doing it and now that it's summer it's getting harder and harder to start. Just replaced the ipr, still doing it. Gonna do an overdue oil change tonight or tomorrow, I'm hopeing that will improve it. I can understand 3 or 4 sec of cranking, but not 10. Truck hads no drivability issues whatsoever. Will an ICP fix it? Change to a heavy-duty 20w-50? (Last oil change was delo 15w-40) The code reader that I have is really basic, and only shows me RPM and map.

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) :: Code P0341 - Replaced Both Cam Sensors Still Bad Miss
I have a 2004 F150 5.4L 2WD auto. I had the cam phasers and timing cover done at the end of 2014 and the truck was great. Back in december, I parked the truck and when I started it the next morning, there was a horrible miss. I left it parked a month or two, then tried starting it up last week. Nothing.
So I had it towed to the shop. They found the starter was bad, and the only code it was throwing was P0341... Cam sensor bank 2. I had it towed back to my house, replaced the starter and the grounds and fired it up. It had the worst miss on the planet and died shortly after being started. I replaced both cam sensors, and now it starts right up and runs... but still has a bad miss.
I used my scanner and its still throwing A P0341 code almost instantly. It sounds like a bad miss that slightly gets better when you give it gas... but its not throwing any misfire codes or anything.
Intrepid :: Won't Start Up When Engine Is At Normal Operating Temperature
Sometimes, when the engine is at normal operating temperature, it won't start up when I turn it off. For example, let's say on my way home I stop off in a supermarket to pick up some stuff. I'll come back out 20 minutes or so later, only to find out my car isn't starting. I'll turn the key and the engine will crank, shake and then immediately die on me [I'm under the impression the engine isn't even starting at this point because tapping the gas does nothing]. Again, this is a problem that is only happening sometimes. I can do the same routine tomorrow and it'll start up flawlessly.
1) This is only an intermittent problem. The problem doesn't seem to be occurring more frequently, but when it does happen, the engine is harder to start. For example, the first time this happened to me, I got it started after one or two tries. After my latest episode, it took me 11 tries to get it running!
2) After the engine does finally start, the engine will run really rough and shake a lot until I tap the gas a few times (which is leading me to believe this is some sort of fuel related problem [sometimes, the engine will start on one try, but will run rough until I tap the gas a few times]).
3) When the car is cold, it starts up flawlessly every time without fail.
4) The car runs mint! No hesitation or otherwise stalling, etc.
What I've done so far to try to remedy the problem:
1) Changed spark plugs
2) Fuel line cleaning/flush
Camry :: Hard To Start When Warm At Operating Temperature

If I don't warm the car up, the car will drive longer. However, once it gets up to operating temperature, it shuts off. The temperature gauge doesn't indicate it is overheating, however if I turn my heat on full blast it does not shut off. I have replaced the fuel filter and spark plugs already and know it could be one of many things but am not sure where to start now.
