I have a 2007 150 5.4 31,000 miles that started knocking and pinging at low rpm, fine above 1000 rpm but i am detecting ackward exhaust tone, after reading several posts on this site about similar complaints i replaced the cam sensors but prob persists.
View 1 RepliesAs stated I have a 2008 F150XLT 5.4 V8. Recently it has started making a knocking noise and very rough idle when warm. It only does it when the truck has been driven slowly or typically when going through a drive through. It sounds like a rod knock but putting it in neutral and revving the engine makes it go away for a while.
View 8 RepliesEngine seems to knock real bad after engine gets hot like its out of time if unplug the vvt solenoids it runs great something is telling them to adjust timing to much.
When it came in it had a cam code and i found cam sensor was broken it had new installed found part of other in engine. Phaser was damaged replaced it. still did it after.
Then I pulled front of engine apart found chain tensioner leaking oil around gasket and then we decided to re time chain. If still doing it.Will let know after air mass meter.
PS no codes at this time

I just bought a 2007 F150 XLT with a Triton 5.4 with 80,000 miles on it. My problem is this, the engine seems to run ok ( a bit rough) until it gets up to running temp and I have driven about 10- 20 miles then most of the time, it starts to act up.
When I am driving it is fine, but when I slow down and come to an idle about 500rpms, it sometimes runs very rough, sounds like a diesel and shakes violently. It feels like it is doing damage. Sometimes it stalls. If I rev it back up immediately it will smooth out.
In speaking to some friends they've suggested things from plugged oil channels, (affecting the cam phasers? All the way to it needing new chains, phasers and guides. I don't want to spend a ton of money doing an improper service repair only to have the issue show up later . But there seems to be a lot of different answers to the same problem. Is the dealer going to be able to diagnose something like this fairly well? Or should I try to narrow it down a bit first?
I am the original owner of a 2006 Prius with 265k miles. I use Mobil 5-30 synthetic oil and I drive a steep hill every day and the engine knocks in the summer afternoons when I use cheap 87 Octane gasoline from Safeway or Costco. If I use better 87 octane gasoline (Chevron, Shell) generally there is less knocking. Also during the winter months no knocking even with cheap gasoline.
During summer I can sometimes make the knocking go away by accelerating or decelerating. The knocking is intermittent and generally occurs only during the steepest parts of the commute. The engine might knock for 30 seconds to 60 seconds before its goes away as I try to change the engine RPM.
Unfortunately I am burning some oil at a rate of approximately half a quart every 5k miles. Generally I watch the oil level, but there have been cases where the oil level has fallen below the lowest mark on the dip stick so I suspect I have some carbon build up.
I've read posts where others have used additives like gumout regane and I've read posts that say not to use additives.
I have a 2002 for explorer 4wd 4.0 it won't accelerate. it's fine to 25, but it pings, and won't go over 40. I've changed to the plugs, wires, coil pack and fuel filter. I've also checked the fuel pressure, and it's 65psi. no codes are being set. I've been told plugged cat, but they're welded on, and no way to test them...

View 1 Replies2 wks ago I was running down I95 at about 95-100 mph (basically floored) in a rush to get somewhere on time. Since then my truck has been running for crap. It threw the p0171 code when I checked it. When driving under normal conditions it pings a lot and my mpg is down about 3 mpg and has this hesitation when you get on it. Even when you accelerate at a normal rate it surges a little, it pings a lot and has a loss of power, about 30-40%. It feels really sluggish and doesnt want to pull and then you will feel it starting to pull a little harder then it starts to surge/hesitate a little again.
Truck has 147k on it. I was having a similar situation until I had the plugs replaced at 125k, so I figured the plugs shouldn't be the problem. So I replaced the fuel and air filters, cleaned the maf w/maf cleaner and Throttle body w/tb cleaner and replaced the pcv with a new one from ford. Still pings bad under load and still has the hesitation/surging and crappy fuel economy. Its running smoother but no fix yet. This is crazy trying to pinpoint this issue. The detonating isnt crappy gas because I used super and it still detonates quite a bit.

I have a 2007 F150 (2wd) with 80k. My truck recently was vibrating under braking so i took it to my mechanic to have the brakes fixed. All the rotors needed to be replaced. In doing so, the front rotors were changed out with the kit that converts the front rotor/bearing assembly into two separate pieces to cut down on maintenance costs in the future. With this being said, after getting this work done, the truck didn't vibrate anymore... that is until i got it out on the highway. Now the truck vibrates from about 45-50 and 70-80 pretty bad. The steering wheel shakes back and forth too. I have gotten the tires balanced in hopes to fix this problem which it didnt. What could this problem be?
View 4 RepliesSo last night my trans have out, going up a slight grade, all of a sudden the engine revved and I had no more 3rd gear. I've done some research, looks like rebuilding it is the only option. I've got my Mustang GT to drive in the meantime, so I am thinking of rebuilding it myself. The truck is an '07 F150 5.4 2WD.
View 7 Repliesi have a 2007 F150 Fx4, with 94,000 miles. When I hit the speed of around 40-45 and I step on the gas it starts to chug until I press harder down the it gets out and runs just fine. The thing that confuses me is it doesn't always do it. Id say about 3 times a week. I am replacing my fuel filter tomorrow. I purchased this truck with 85k on it, and this just started happening. The spark plugs have never been changed. And am thinking about taking it in to get those done too. I also tested all my injectors and they are all working. No codes have been thrown either.
View 6 RepliesI have a bit of a question about my 2007 Ford F-150 w/ the 5.4 3V. I don't know how long it's been doing this, I just happened to notice it not long ago. Whenever I rev the truck (doesn't matter if it's in Park or Drive) in between 800-1,000 RPMs it makes a "rattle" type sound - like a "rat-tat-tat-tat" I guess is one way of putting it. It only does it when the engine is hot, it won't do it when it cools down some. The truck has 63,000 miles and I've always ran the recommended 5W-20 weight oil. Engine runs good, no power-loss or anything like that. I have posted a video on YouTube of the sound. If you want to skip my talking in the video to get to the sound, then skip to 1 minute and 40 seconds of the video.

My truck has been jolting lately around 40-50mph. I have done some research, and I believe its one of the coils going out or is out. The problem is I can't get it to throw the ck engine light. So it's making it hard to determine which coil is actually bad. What to do? I honestly dont want to spend the money replacing every coil at this point.

It appears the odometer backlight problem has been around for a long time, aon many models. 2007 f150 Supercrew? Just had the engine replaced under warrenty at 35600 miles. Just as soon as I get 50 miles out of warranty the the odometer light goes out.

What would be the largest tire size replacement i could use in an all terrain tire? (thinking about BFG or Bridgestone Revo)...
I know nothing about vehicles as far as exhaust and tire size. But what i want to ask is what is causing my 2007 ford f150 4.6l to rev up while in drive while im just costing. see i was at about 20-30 miles per hour and almost to 2 rpms and repeatedly my truck would rev in the range of 20 to 30 miles per hour for about 1 seconds but would go back to normal after that rev. I rely on my truck for work and also while I was in Park at a target parking lot my truck began to rev up Wow and park I don't know what is causing this....
View 3 RepliesMy sons 9 yr old serpentine finally gave up on him. Imagine that... It ripped the clutch wires out very close to the fan clutch. Can those be spliced back or disassembled and soldered inside the clutch or is there a resistance factor that must be met on those wires? I just can't see replacing a fan clutch just because of broken wires. Even though it would be a hard lesson learned for him.....
