Ford F-150 (2004-2008) :: Code P0175 Cleared Up - Hesitates On Takeoff And Slight Shake Like A Misfire
Apr 9, 2012
I have a 2005 F150 5.4 and I recently got a p0175 code. I've replaced the M.A.F. sensor, fuel injectors, fuel filter, new plugs, coils and checked the vac lines but I'm still getting a p0175 code. Ive reset my P.C.M. and the code stopped for 2 weeks but returned later. The truck runs fine when I erase the code but when it returns it hesitates on take off and has a slight shake like a misfire and it makes a bubbly popping sound from the exhaust. Im at a loss of what to do next! Could this be a code stuck in the P.C.M.? My mechanic thinks it may be the cam phasers!

So, after putting new tires on my truck about 2 years, I noticed a slight shake when I drove at about 90kph. I let it go for quite some time thinking it was just a balance issue.
Well this weekend I spent 7 hours washing, waxing, and polishing my truck. It was worth. The rims reflect the moonlight now. It's amazing. During this washing, I scrubbed in behind the spokes of the rims. I found a big chunk of mud. Well surprise surprise, my shake at 90kph went away... or so I thought.
I no longer have the shake when driving at 90 or accelerating through 90kph like I used to. Now I have the shake when I let off the gas at 100 and drop to 80kph. It shakes at 95 through 90, and then goes away.
What is causing this? The parking brake is never used, and is showing no signs of engaging while driving. Is this a driveshaft issue?

.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.

First off its a 2006 F150 king ranch with the intercooled roush kit and roush tune. Last couple weeks its progressed from a slight stumble on start up, to now after its been off for a few hours it may start and run rough for a second, or, it may start then die, and then have to crank for at least 5 seconds before it starts. After it starts it seems to run fine. I've thrown the P0172 and P0175 code a few times. I downloaded the torque android app and did some data logging. Can you learn anything from the long term fuel trim?

At 89,000 miles I replaced my plugs with autzone autolites and also replaced my fuel filter. Shortly there after the truck started to shutter and shake while miss firing giving a 0307 code. After checking that plug and replacing it, moving the COPs across the engine from each other the miss firing continued under the 0307 code. The miss firing mostly occurred when I was around 50 MPH, under slight strain with a little acceleration. If I powered through it most of the time it would clear out. Occasionally it was bad enough to where I had to pull over.
I trouble shot this for about a month before it got more consistent and worse. I took it to the shop where they tested the compression on the cylinder and also tested each coil. All check out OK. They recommended I replace all plugs with motorcrafts and the boots on the coils. In the process of doing that I discovered a loose plug in the #2 cylinder. I pulled it out and found that it was scorched and the metal was slightly tweaked at the tip. Not sure how it got loose or how it got burned, but figured that I found the problem. All plugs and boots replaced!
Two days later more miss firing. This time with a 0305 code. Occurs again on a grade at around 50 MPH with slight acceleration. I pulled that plug and the plug in the cylinder where the loose plug was found. Nothing seemed to be wrong. The plugs seemed a little brown where I put anti seize on but that I figured was normal. I then moved coils again. The miss fire continued and the code did not move. There is still a rough idle and occasional humming coming from the engine.
Is the loose burnt plug a separate issue or is there something causing all the miss fires that backed my plug out. I'm lost on my next step to take. Im getting married in two weeks so needless to say spending more and more money on this issue let alone time is making things so stressful. Besides the fact that I think my engine going to blow up on me every time it miss fires bad.

Getting code P0022, which is over retarded cam position, drivers side bank. My 2004 F150 has the 5.8 triton. I have replaced all cam phasers and tensioner a as well as the timing chains. I have also replaced both VCT solenoids. Before I was getting codes for both banks, now just the code mentioned above with a slight ticking as well. My question is this... What am I not seeing? What could be causing this?? Would it be beneficial t get the lockout kit for the phasers to always keep them open?? Seems to stall a little at very low RPM like when you are off-road.

I know there is a tun of info on the spark plug problem on the f-150. Here is the problem I have and I don't know where else to look.
Cylinder #3 misfires
1. swapped coil with #2 cylinder and still throws #3 misfire code.
2. Changed the plug on #3 and still the same code #3 misfire.
Where to look next?

This happened xmas shopping with the wife. Started misfiring on the highway,took the 1st exit to find a garage as I am 20kms from home. The vibrations were worse at stop, but made it to a garage. They gave me the p0301 misfire cylinder 1, said they don't touch 5.4 plugs, told me to go to ford 2kms down the road. NICE. 4 in the pm, FORD dealer worse case scenario. Nope gave me a loaner told me come back at 930am. Truck was just waiting for an injector when I arrived. Plug & coil were good injector was shot,changed the fuel filter & oil change.

Having a misfire problem I can't track down. First issue was random cylinder 8 misfire code. Checked everything, nothing obvious. Cleared code, problem stopped and engine ran fine. Then came back, cylinder 8 misfire. Swapped coil with #5 but problem did not return. Since I assumed it would come back, I went ahead and bought Accell supercoils and new Motorcraft plugs and replaced them all (120k miles, no broken plugs ). Truck ran great on the test drive! Then it sits overnight and bam, cylinder 5 misfire as soon as I start it next morning. Then after messing with it I get cylinder 5 bad coil (code 355 I think). Put one of the Ford factory coils back back on #5, no change and still misfiring. New plug, new coil on all cylinders... Why did it move from #8 to #5? If it was an in injector, seems it would still be #8 since I did not mess with those.

I have a 2004 f150 with the 5.4 and was wondering what would cause a spark plug to do this. Its on cylinder 6 and i have pulled the codes off of the truck before and one was PO306 which is misfire and can't remember other one but it was saying system was too rich. I have only has this spark plug in maybe 500 miles. but was getting a misfire code before that. Do you think it could be a coil or the injector?

Started as I was warming up the truck,a slight vibration/shudder. First thing that came to mind was F150. Torqued words of wisdom that it might come back, I had a p0301 before. Had no CEL, so decided to drive it to see if it got worse. Turned onto the main road and on came the CEL. Pulled into my FORD dealer, told him about my problem. Code P0308 misfire on #8cylinder was the read out, COP was done and the plug. 40 min of labor. She's even quieter than when #1 got changed.

I have a 2006 F150 with a cylinder #1 misfire only code p0301. I have done new spark plugs, new coil packs, and new fuel injector on cylinder #1 with no luck. What to do next?

Friend has a 2006 with the 4.6 motor. From time to time he gets a random misfire code ( I think its 0316).. He claims it will only do it when the gas tank is less that half full. I don't see any correlation between fuel level and the code. I am going to check fuel trim values, etc, when the code is set, this weekend.... all I can assume is low fuel pressure which sets the code... Any problem with the pressure module or fuel pump / discharge hose that is related to low level in the tank ?

I have experienced a hesitation on my truck since I purchased it 6 months ago. I get a one to two second hesitation at take off from a stop. I have checked the back pressure tube and the one that goes to the turbo controller no problems. I have a Edge CTS programmer that only shows ... for EBP.

Having 3 new codes coming up. P0306-misfire on cylinder 6, p0158, p2272. Use my truck as a daily driver for work. Driving along before 80km/h is not to bad but can still feel a little loss of power. If i step down on gas the truck has no power and sounds like maybe cat converter is plugged. If truck is pushed to limit she will make it to her 4000 rpm and will change her gears. So i'm just glad its not tranny.

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 picked up a 2004 Mercury Mountaineer, 4.0 with 113,000 miles. OBD reader says misfire on 3 cylinders.. Installed new plug wires first.. nothing.. going to install plugs next when she is cold. Now, am I really looking at replacing the coil pack to end the misfire codes? She likes to buck and shake and idle around 400 rpms.. I know that is too low..

I am getting 14MPG out of my 2007 with a 4.2L 5 speed manual single cab. That seems pretty low to me considering the HWY MPG is rated at 19mpg.
My son and I have also noticed when taking off from a stop it is very easy to kill the engine, it seems to happen more so in Reverse but does it a lot going forward. I have driven many stick shifts and this one is by far the worst as far as it dying on take off, really I have never seen one this bad.
I have also noticed some spark knocking at HWY speeds and it also feels like it has a miss a idle but when you push the gas it runs fine.
Installed Motorcraft Platinum plugs a few months back and checked all the gaps. Also new orielly brand plug wires at the same time.

Which one is the ect? One is the ect and one is a switch for something?
Just gone done switching that POS plastic thermostat housing thing, both sensors were replaced not sure which one is throwing the code.
I have cleared the code and it keeps coming back.

As I said when I take off from a dead stop I can feel a clunk or a bump that feels like it is coming from the rear wheels. I can feel it more than I can hear it, although I can hear it a little. It is difficult to describe this. It is only for a second and kinda feels like the rear wheels have no traction then it bumps and takes off. If I ease into the accelerator I can avoid it, but I don't have to hit it real hard at all to get it to do it. I am sure it is not u-joints as I put a brand new drive shaft from driveshaft specialist on in the spring.
