Ford F-150 (2004-2008) :: V8 - Engine Knocks At Idle?
As 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.

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?

When my truck sits all day and its cold out, my truck in 2WD will make a whining sound going down the road, sometimes its a grinding sound almost. Appears to be coming from the passenger side of the truck towards the front. Engaging 4x4 gets rid of the noise, and the noise will usually disappear after the truck has been running and warmed up. I've changed my ball joints recently and everything looked good and yes it had done it a time or two before hand. What causes this, and how do I fix it?

I started having an issue when the weather changed here on the East this weekend. When I start my car in the morning the engine knocks for about 30 seconds and then stops. I also recently got an oil change at some local mechanic shop and wondered if that might be the issue. I checked the oil and it was stellar this morning but I'm not sure what kind they put in there. I would assume it's the required type.

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.

View 4 RepliesFord :: 2002 - Engine Knocks Loudly At Start Up / Reaching To Stop?
I have a 2002 Crown Victoria LX. The engine runs great with the exception of a loud knocking sound sometimes when starting or stopping the engine. When starting, it's a single loud knock after the engine turns over. When stopping, it's anywhere from one to several as the engine motion comes to a stop. When it's several (probably 4 or 5) they are quick but it's apparent that the rate slows down slightly over time, as if it's a moving part inside the engine coming to a stop. It is worth noting that about one-third of the time when turning the car on or off, there is no noticeable knocking sound whatsoever. Maybe something is loose inside?

We have a 2006 F150 w/new engine, new everything but transmission and cat. converter. When driving in warm weather with the AC on and at low speeds or idle the engine will knock and want to cut out but you rev and turn off the AC and it stops. Only with AC on. We replaced fuel filter, fan throttle took to dealer and updated the software which it stopped for 3 days and started again today. Could it have to do with AC compressor or low refrigerant?
View 4 RepliesFord Excursion :: Engine Knocks Badly / Revs Erratically And All Gauges Not Working
The other day I bought an sct tuner for my excursion and its been a little glitchy, likes to freeze up and lock out my ecu.
I was driving yesterday and today I try to turn it on and my engine knocks badly revs erratically and all gauges weren't working so i shut it off. I tried to start up again and it flashes the theft light and abs light. Won't crank won't do anything my whole engine is locked out.
So i tried reverting the ecu back to stock. I did this several times once it simply lost power and shut off at the end another time it said wrong vehicle and the final time it said completed.
Now when i try to start up it does the same thing and will not do anything but flash lights at me... When I downloaded the file it said select vehicle: 6.0 superduty. That was the only choice, and the guy at the store said that the truck tuner will work in my excursion I specifically asked if this works in the ex.
I really need my truck otherwise I will he paying hundreds in taxi fare. I tried calling the store and sct but both are closed on weekends.

2006 STX 4.6 .... I recently changed my oil a couple of weeks back. I've noticed spots of oil on the driveway. I thought it may be coming from the oil pan drain plug but i checked it and it seems to be coming from where the transmission connects to the engine. Lotta oil on the bell housing. That's where it looks like it's dripping off of. Could it be the rear main seal?

2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00

Eng speed 1665
