My 2005 F150 makes a diesel sound when I accelerate. It only does it between 1600 to 1800 RPM and stops. It only does it in overdrive. Its a 5.4 liter with about 95000 miles on it. What this could be? I cant tell if the noise is coming from the tranny or engine.
View 1 RepliesBought an 05 FX4 SuperCab in May - been in shop twice for a "clunking" sound when accelerating from a dead stop. Dealer says it's "operating as intended" and that no damage was being if I continue to drive. I thought it was a rear problem with the limited slip. Dealer says it's the tranny and that Ford is looking into the problem (apparently quite a few are coming back). She runs smooth and shifts fine once she gets going. Just starting from a complete stop feels painfully wrong.
View 14 RepliesMy 2012 F250 6.2L (Gas) engine developed a noticeable drone/vibration when in drive between 1600 - 1800rpm. RPMs above and below that range is fine. But when accelerating, as soon as the RPMs reach 1600, you can feel a slight vibration through the gas pedal and a noticeable sharp draon/moan up till about 1800 or 1900 rpm, then its normal.
I took it to my ford dealer and took the service manager out for a test drive. He said that there is a drone and slight vibration withing that RPM range. He thought that the engine mounts may be loose. But aside all that, he felt something was off and wrote up the service order.
When to pick up the truck and now the service manager changes his tune and said that the drone is normal and happens on all 6.2L super duties.
To be honest, I have the feeling he is pulling my chain.
my 05 is giving me these mini shakes when I accelerate and slow down. I also get a little bit at highway speeds. I was walking around the truck today and I noticed that the back right tire doesn't have a weight on it. I thought this was wierd. Could a weight have fallen off thus causing the vibrations, or is this normal for one wheel to not have a weight?
View 13 RepliesI've had my 2006 XLT F150 (5.4L) for about a month now and have recently noticed what I can only describe as a 'smacking' sound under my truck when I accelerate quickly. It sounds as if I had something stuck to my drive shaft that is slapping the underside of my truck....except I don't. I don't think that its the timing chain because it seems to be coming from under the cab (between drivers/passenger seat maybe). I hear it most often if I try to quickly accelerate from a normal speed (50mph or so) to pass another vehicle. I do not hear it otherwise. Starts with a 'tink tink' then sounds like something hitting the underside. I'm perplexed at what this could be.
View 6 RepliesMy truck has 57k miles on it. At 1800-2100 RPM it whines under or over it is just fine. it has a new air filter in it as well, still makes the noise, it doesn't matter what gear i am in, it only does this under load. if i free rev it , it will not do it.
View 2 Replies have been lurking the forum for the last several months ever since I bought my 2008 F150. I bought it used from a dealership and have had it at their shop no less than seven times since I bought it in March, all for the same things.
The first thing I noticed shortly after buying the truck was that after the truck warmed up it would idle rough. My chief complaint by far, I took the truck in to be looked at and this is when all the real fun began. Similarly I had intermittent power steering that I asked to have looked at.
I was told the fuel filter was completely clogged. They cleaned it and assured me all was well. They also bled the power steering system because apparently someone had changed the PS pump and not bled the system afterwards. I got into the truck to leave and it was idling no better than when I dropped it off. I complained again and was told that "this is just how this truck idles" and called BS. They offered to have the throttle body cleaned for me the next day to alleviate any remnants of rough idle.
Had the throttle body cleaned the next day and took the truck home. After about an hour or two I was still thoroughly dissatisfied with the idle and called back to complain. I forgot to mention that I bought my truck from a Chevrolet dealer who had just taken it in on trade about three days before I bought it. Because I complained they offered to send the truck to a Ford dealership for further diagnosis.
The Ford dealership found fouled plugs, a cracked intake manifold and the water pump and fan clutch both had excessive play. They said those would create a rocking sensation which could be misinterpreted as a rough idle. Over $2500 the Chevy dealership paid them and I was called to come pick up the truck.
I didn't even make it out of the parking lot because the truck was whining something fierce. I couldn't believe no one QC'd the vehicle and complained again. Next morning I am called and they said that the Ford dealership had put the intake manifold gasket in wrong and it had been corrected and I could come pick up the truck.
I go pick up the truck and note that not only is the idle still not right, but now the truck is making a hissing/squealing noise when the truck hits 1800/1900 RPM's. Its strange because its not really RPM specific as it is specific to the pedal position. Accelerating or decelerating causes it to go away but its there nonetheless. Whats worse is that in highway driving at 65 MPH, the pedal is in just the wrong position and it hisses constantly. This sound never goes away...and once its been heard its impossible to unhear.
I complain again and they send the truck back to the Ford dealership. At this point I'm dealing directly with the Director of Service because mine has become a high priority case. The Service Director drives with me, confirms my problem and takes the truck himself to Ford. He drives with their shop foreman and they too confirm the problem.
A week goes by and Ford tells him its wind noise. This is complete bullarky because it happens whether I'm going 20 or 65. He calls them on it and they keep the truck another couple days. They call back and say the truck has nothing mechanically wrong with it and that they are done. Service Director goes and picks up the truck and takes it to a second Ford dealership.
Three days go by and they call and claim Eureka! We've found the problem! Clogged catalytic converter causing air flow restrictions. They replace two converters and I go to pick up the truck. It runs like garbage. Further the sound is still there. Call Chevy, leave the truck and take their loaner back home. Next morning Ford's Foreman calls and basically tells me that there's nothing else wrong with my truck and that he even reprogrammed the PCM (which is why it runs to bad all the time now I guess) to get rid of the idle problems.
Long story short here's everything thats been done:
- Cleaned a clogged fuel filter
- Replaced fouled plugs
- Replaced the intake manifold and gaskets
- Replaced the fan belt
- Replaced the fan clutch
- Replaced the water pump
- Replaced two catalytic converters
- Cleaned the throttle body
- Bled the PS system
- Reprogrammed the PCM and transmission control module
After all of this I still have a hissing sound when I accelerate (video 1:
It seems the truck runs worse once its warmed up and even worse once the AC is turned on. I'm sure he programmed the PCM wrong and thats what is causing the truck to run rough.
I have a 2005 F150 S Crew and have been maintaining it regularly. I started having a jerking while accelerating lightly or in between shifting then the overdrive light comes on and then flashes trans fault on dash. I took it to the local tranny shop who fixed the problem however about a year later it started doing it again. What the problem could be before I have to spend another bucks?
View 4 RepliesI have a 2005 FX4 with a 5.4L. I have noticed in the past 3 months that when I mash the go pedal hard the engine misses and there is a popping sound. My gas mileage has gone down 2-3 MPG.
View 10 RepliesMy 05 Supercrew 4X4 with 172k miles started making a horrible noise these last couple days. It sounds like its coming from the front passenger side area. The best I can describe is that it sounds like an electric tool motor with bad bearings. I'll be driving along at 45mph or above and every now and then I'll hear a really bad bearing squeal. It's bad enough that I can feel the extra friction caused by the squeal start to slow my truck down. It's vehicle speed related. I know what a bad wheel bearing sounds like and this is nothing like that. It's gotten bad enough I'm nervous to drive anywhere.
View 4 RepliesAt least that's when I notice it,... right in that range, seems the car hesitates and then starts up again and hesitates,... and you can see the tachometer go up to around 2 k and then down to 1600 rpm,.. but I am not accelerating with the gas peddle. Thoughts on what is causing this..
View 2 RepliesI have a 2001 Camry LE, 4 cyl, 2.2 liter, automatic transmission, 163Kmiles on it.
I'm hearing what sounds to me rather like a grindy sound at around 1400-1600 RPM. Initially the Camry seemed to do it only after getting into 2nd gear at about 10MPH, but now i see that it is associated with RPM and not the gear so much (the noise is less frequent and less loud in 2nd and 3rd gear- not noticing it ever at above that). I should say that the Camry has been making lots of noises since a new exhaust was put in by a cheap Bosnian shop.
It seems to only make that particular grindy noise when starting from a dead stop, but not if i was already coasting at all. So far as i can tell it seems to only happen about half the time- if I'm accelerating very slowly it doesn't seem to happen much. If i start climbing a hill after a dead stop it seems to come on fairly reliably.
It does not seem to make the noise when passing down through 1600 RPM while slowing down or revving down.
When i started the Camry up today, the noise cropped up well before i got to 8MPH (where it typically shifts into 2nd gear). Which is to say the noise appeared before it even started to shift out of 1st gear.
If i stay in Drive or Reverse and apply the brake so as to not go anywhere, the noise generally starts around 1600RPM. Since the car isn't moving, i think this might rule out the transmission. I hope.
However when in Neutral or Park and i bring the engine up to 1600RPM and beyond, the noise does not appear. So that's perhaps not so good. Of course my car idles a lot better/smoother in N and P than it does in D or R. It's rather rough idling in D and R.
I'm hoping maybe it's a vibration issue- something like harmonic amplification- where something only rattles in a certain frequency range. I pulled up next to a brick wall, kept on the brake, went into D and got up near 1600RPM and the reflected noise does strike me more now as maybe being less a grindy noise and more of a rattly vibration.
The Bosnian shop who fixed up my exhaust were too quick to dismiss the noises i heard after they worked on it. I think maybe something is loose. I hope. (I could feel air leaving the flexpipe's woven area itself but don't know if this is normal.)
Going up hills increases the likelihood of the noise appearing (so i take this to be suggestive that it IS the transmission).
However on a flat road if i hit the gas to quickly get up to 1600RPM before I'm any where near auto shifting out of 1st gear, the noise also usually appears (so i take this to be suggestive that this is not the transmission). I've also gotten the noise to not appear until well into 2nd gear.
The fairly-repeatable noise appearing in the 1600RPM zone regardless of my gear position gives me some hope that the xmission is not the source of the noise. So on balance, i think there's some indication it's the transmission, but there's also evidence that the source is other than the transmission.
The noise does not occur in Neutral or Park while revving up to 1600RPM. But then too, the engine, exhaust and vibrations always seem considerably less in N or P, as opposed to being in Drive (or Reverse). Why my Camry is quieter and more smooth in N and P as opposed to D or R? In the latter two modes, i imagine the transmission is engaged? And that the transmission is unengaged in P and N? And would that make the car louder or vibrate more, at least under certain conditions? Is the engine under less load in P and N?
And are noises at certain RPMs in D or R, but not in P or N indicative of Transmission problems? I notice the shop overfilled the transmission fluid every time i've had it changed.
Back again.. I just replaced the HPOP and IPR valve on my truck a few weeks ago. While the turbo was out I cleaned it and applied a small amount of anti seize on the unison ring. When installing the turbo I had moved the y-pipe a little to get the turbo in place. About a week after it was running again I started to get a squealing noise under acceleration. The noise isn't a whistle like the turbo but an actual squeal. Its a little bit louder than the turbo whistle. If I am in park and rev the engine it doesn't happen. It only happens when I accelerate and seems to be when there is boost. If I let off the gas pedal the noise stops. I don't have an issue with making boost. I did replace the turbo boot when it was apart a few weeks ago so I don't think that is the problem I checked the y-pipe clamp and down-pipe clamp and both are fine. I replaced the serpentine belt this past weekend and checked all pulleys, they were all very good with no play. Another thing, the pitch of the noise seems to change with rpm's too. What could be causing this type of noise?
View 14 RepliesSounds like an air leak when accelerating, and constant at mid/higher rpm's while driving. Hard to tell when parked.
View 2 RepliesI have a 2005 F250 with 186K miles. I do minor work on my vehicles but have little experience working on my diesel. I was accelerating when I heard a pop and a hiss similar to disconnecting an air hose from an air compressor. Total loss of turbo power. No turbo reading on the turbo gauge on dash. No loss of oil. No smoke. Oil and coolant look fine. Took off turbo and everything appeared to operate like it should (according to YouTube videos). Inspected lines and rubber boots.
Rubber has some cracks but not certain if they are holes. How small/large of a hole would cause total loss? Was originally scared to take it to a shop knowing they could name their price. Not opposed to taking it somewhere now knowing the turbo works but obviously would rather save the money. Any tips on troubleshooting? I'm not opposed to proactively replacing parts/sensors as the truck has given me 186k and I plan to keep it as long as possible.
Recently purchased a 2005 F250 6.0. I noticed that sometimes when I brake it feels strange...like ABS activating in rear or something. Usually at 15-30mph when braking right after accelerating. Its a bit difficult to explain. I'm planning on getting a break inspection soon.

Ratchet buzz noise my truck makes. Is not present until motor warms up. Noise is not present as much at idle but when you accelerate upwards to 1800 RPMs it makes such an obnoxious buzzing noise its embarrassing. Noise seems to come from top center area of motor.....
I've tried to do some internet search on my dad camry that is stuttering at 1800 - 2000 rpm. the car drives fine & all but every time, the rpm is at 1800 - 2000, the car would stutter or it is not smooth and/or normal.
View 14 Replies2005 Dodge SRT-10 Quad Cab.... There is a strange noise, or perhaps I should say noises that sound most of the time like a grating/grinding sound. Occasionally it has less of that mechanical sound, and more of..well, like blowing air over your tongue with a lot of saliva in the way (like a cat purring with a hairball in its mouth??). Anyway, the ONLY constant I have found is that it only happens when I am accelerating (but not every time I accelerate). Most often (again there have been exceptions) it happens between 1500 & 2500 RPMs...typically just before the transmission would be inclined to shift to a higher gear - if it does shift into the higher gear, the noise stops.
Also, the moment I take my foot off of the gas pedal, the sound stops. About a third of the time, I can feel a slight vibration via my feet when the noise is stronger sounding. On two occasions (this is over a period of approximately 1 year) The sound was extremely harsh, and the truck was shaking.When I took it in the first time they told me it was the catalytic converter, and replaced it. When that didn't fix the problem, they decided it must be the other catalytic converter (yes it has two). That didn't fix the problem either.Ordinarily, rather than simply have them replace half the parts in the truck I would wait until something completely failed, thus making the culprit obvious. However, I am moving soon... and I don't want to be driving half way across the country pulling a large trailer and have the drive shaft, or transmission, or whatever - fall out.
As the title says, I have a 2013 accent with an automatic transmission and 63k miles. Just bought it, used. The car seems to be fine, except I've noticed that when I am giving the engine some gas and it has work to do, i.e. accelerating or going up a hill, it will squeek / chirp a bit, but only between 1800 and 2000 rpm. Its not very loud, and goes away when it's outside of that rpm range. It seems to happen more often once the engine is warm and when the car is already at speed, rather than when it's revving in park or accelerating from a standstill.
Here's a 47 second video I took inside the car while driving. [URL] .....
It's a bit quiet, sry about that, all I have is windows movie maker. The sound is present at 0:08, 0:16, 0:36, and 0:45.
Is this something I should worry about? I saw another thread which mentioned "dieseling", a sound like a diesel engine caused by a bad knock sensor, leading to incorrect ignition/valve timing. It sounds a little bit like a diesel engine to me, is this the same thing?
I've recently purchased a used 2008 Prius with 77000 miles. I was a bit apprehensive but have started to fall in love with this car. After running some errands yesterday, I heard a strange buzzz, coming from the middle of the engine compartment. When I'm in the car is sounds like it is front of me, but seems to be more in the middle when you pop the hood.
And when I'm accelerating, there is now a strong hum almost like a revving sound and it increases the faster I go. I am also getting the Maint Reqd light flashing as I turn on the car, but it goes away when the ICE kicks in, just started this in the past week. I have put about 500 miles on it since I bought it and I did buy an extended warranty.
I am getting between 41-44 mpg, depending on traffic conditions, around town, so the MPG, so far has not been effected.
