Ford F-150 - 1997-2003 :: 2001 - Cold Air Intake Making Humming Noise?
I just installed a cold air intake on my 01 f150 with a 5.4 and as soon as i started it after the install there is a loud humming coming from the intake but with some throttle it goes away. ive looked around on some of the other threads that suggest the iac valve usually causes this humming noise but why would it go bad with the install?? also i broke iac breather trying to remove it from the old hose to install with the new hose so i just connected the new hose directly to the inlet behind the intake until i can get another one to replace it. could this be causing the humming as well??

First off I have a 1997 F-150 4.6 with 205,000 miles on it.. stock engine and tranny. It's been a great truck and never given me any major problems. But recently something under the hood (wish i could be more specific) makes a really loud HUMMING noise (almost sound like a trumpet). For example- say im driving on the highway and i let off the gas, this humming noise will appear and it is very loud, but right when i give the engine some gas the humming goes away.
Or also when I am driving through town, when i come to a stop light, let off the gas to apply the breaks, this humming noise will come about. what i have to do is stick the truck in neutral and give it a big rev (which i do like hearing my exhaust so it isn't always annoying) and then it stops. note though, it doesnt happen every single time i let off the gas, however it is pretty frequent.
do yall think this is in the air intake system? thatd be my only guess because when i rev the engine it quits, but one thing is it sounds like it comes more from the passenger side of the truck, and it seems to occur more often when the temperature outside is cold. im completely stumped by this one, ive never heard anything like it.
Ford F-150 - 1997-2003 :: Steam And Water Coming Out Of Intake
My truck over heated and I now have a looks like a pin hole leak next to the front injector on the left side looking at it. I have used sealers and it does not work. Water pools around the injector. Does this sound like a cracked intake housing? I have done many repairs but this is something I'm not sure I want to do. I can get a new intake setup for 160.00 on rock auto but ford would be in the 300 or more just for the part.

I tried searching, but couldn't find anything. I have a '97 F-150 with the 5.4L and I have a plastic line coming off of my intake that I don't know where it is supposed to go. I don't know how or when it got disconnected, but I can't seem to find anything within reach of it that it can connect to.

I have a 2003 F150 manual 4WD with 4.6L engine and 165000 miles. When i am driving i feel a vibration in the steering wheel and on floor board that intensifies when i press the accelerator. I do hear an irregular humming that sounds like it is coming from the driver side front. I checked the wheel for any play but it was very tight. i check tie rod ends, ball joints no play. i recently changed both u-joints on the rear shaft and the bearing hub on the passenger side front. Also, the steering feels a little 'wobbly' when i make sharp turns. it almost feels like it is giving. What else should i check?

View 3 RepliesFord F-150 - 1997-2003 :: Loud Single Knocking Noise Coming From Behind The Dash When Turn Key On
The last couple days my truck (1997 f150 4.6l) has been having starting issues. At first it would just turn over and not start then the battery would die. So i bought a new battery and yesterday now its starts sometimes but when trying to start it while its ttuning over it stops then starts turning and starts up. Then i drive wherever I am going when i get back in to start there's nothing.
Its not turning over at all but when i turn the key there is a loud single knocking noise coming from behind the dash near the passenger floor vent. Actually there ate two noise from the same area, one when i initially trun the key and another when i release the key. But after just sitting there doing this it will finally turn over and start. What this is, there are no codes being thrown besides my dreaded P0401 which i cant seem to get rid of either. Ive changed every part that has to do with the egr system and cleaned the throttle body replaced vacuum lines and still the code.

Not sure if my 13' rx350 is haunted. Went in the garage (car had been sitting for hrs) and heard this pound humming. Checked everything in the garage and kneel down near driver side /passenger door and could hear the humming coming from under the car. Checked to see if the radiator fan was running ..nope. This has occurred on 2 occasions that I know as it seems to be random so I am concerned if I take it to dealer I'll get the "can't duplicate"...

So I installed my intake....again this weekend and have been monitoring it to make sure it doesn't pop off again. When you first start up, there is a very loud growl coming from the intake that lasts about 20 seconds. I also noticed that the breather filter kicks in during this time as well. Is this normal? I would yes but want to understand exactly why...

View 6 RepliesLexus :: Loud Whirring / Humming / Whining Noise Coming From Engine
I have a 2006 lexus es 330 that just turned over 90,000 miles. My dad and I have done the regular maintenance on it so far but this weekend after a 3 hour drive, I turned the car back on and a loud whirring/humming/whining noise was coming from the engine. It gets slightly louder with acceleration, but I can barely hear it once I've picked up speed (but it's still there.) It still happens when I am in neutral. It sounds like it is coming from the passenger side of the engine. Close to the power steering pump area, but the power steering fluid is full (although it is a very dark/black color and has a slight smell...not sure if this is normal.) I'm not having any trouble or hesitation while steering. The rack is operating smoothly and it is not leaking. I plan on taking it into the shop but wanted to go in educated.

View 14 RepliesNeon :: 2000 Dodge - Loud Humming Noise Coming From Transmission Area Of The Car
As I accelerate, there is a humming noise that comes from the transmission area of the car. It does not make the noise when I am in idle, nor if i put the transmission in neutral and rev the engine.
When driving slow the noise is very subtle. As I accelerate faster the noise gets louder. The noise becomes the loudest at 60 mph. Above 60 it seems to calm down some. The noise is like a constant, deep humming sound. The noise gets softer as I slow down and then is gone when at idle again. To me it seems related to the speed of the tire or the CV half shafts turning or something rubbing in the transmission as the car goes faster. However the sound doesn't change when the transmission shifts. It stays constant and only gets louder as I go faster and then softer as I slow down.
While driving and turning hard to the left the sounds almost disappears until the car straightens out again. I have replaced the struts on all four wheels and this seems to only have caused the sound to get louder. I have also inspected the CV joints. There doesn't seem to be any cracks or signs of wear to all 4 joints. And I repacked the bearings.
The only other things I can think of is the cv half shafts are actually bad and need to be replaced. Or the motor mounts are not aligned/worn out and need to be replaced. Or the kickdown band and low reverse band on the transmission need to be readjusted. Or the transmission is has a problem (however it doesn't slip when driving).
Buick - Lesabre :: Loud Humming Noise Coming From The Front When Begin To Accelerate
As I begin to accelerate a humming sound from the front of the car begins. The noise becomes more pronounced the faster I go. No additional noise is made when I brake or turn, nor does it appear to be any noise when I went in reverse. I made a 180 mile trip on Sunday with no problems, although I did travel at closer to 55mph than 65. The car has 170,000 miles on it and has had most of its scheduled maintenance performed.
View 3 RepliesStalling - Gasoline - Pump - Chevrolet - Noises - Lumina :: 1997 - Loud Humming Noise?
I bought the car( like six months ago) there has always been a loud humming noise from the fuel pump ( I'm pretty sure it is the fuel pump anyways) not the normal whirring noise the fuel pump makes but a hum you can hear about ten feet away. Had no issues till just lately when the afternoons are well into a hundred degrees. That is when my car starts giving me issues. After one of these hot days on my ride home from work, I had just come off the highway and stopped at a stop light when I felt the engine bogging out, the engine stalled and I had to push it to the side of the road.
Its worth mentioning that this humming noise is much louder in the heat than the cool morning then when I turned the key to hear the fuel pump(auto fuel inject) it was louder than it has ever been, and would keep stalling on the way home, I had at the most a quarter tank of gas (gas boy is busted/stuck I think) the fuel pump is bad? Could it be the sock? I thought I read somewhere that my girl pump uses gas to cool down, and that having the tank any less than a quarter could lead to the fuel pump overheating????
Ford F-150 - 1997-2003 :: 4.2L V6 - Intake Manifold Gasket Leak?
I've got a 1997 F150 with the 4.2L V6. Before I got it last summer I did some research, but apparently missed the issue with the intake manifold gasket leaks on these early engines. It seems to be a very slow leak, but obviously I want to get it fixed. I called Ford to see if it had had the recall work done on it, but all they could tell me is that there wasn't an open recall on my truck (with the exception of the recent fuel tank strap recall). Their system apparently only goes back 10 years, so they couldn't even see the freakin' recall. So, I've got a few questions:
1) I know I didn't post much info, but does this seem like an intake manifold leak?
2) Are there any special tools needed to change out the gasket myself?
3) Can you all recommend any replacement gaskets? I found a few different manufacturers of gaskets, but I'm sure some are better than others.
4) Can this issue cause the computer to throw the loose gas cap code (P0455 if I recall correctly).
5) Would it be worth it to just get a new truck? I really wanted a diesel in the first place, but I also hate to give up on a nice truck with only 115,000 miles.
