Ford Aerostar :: Intake Ducts Making Loud Moan When Slowing Down To A Stop Or At Low Speeds
Apr 4, 2013
Lately, when slowing down to a stop, or very slow speeds, the intake ducts make a very loud moan. It sounds like a muted horn really. Sometimes, I can put it in park, and it'll be making the noise. Open the hood, and it feels like it is coming from the plastic intake tube. When it does this, the motor likely stalls out, and needs to be restarted.
Another issue, we cruise with it at roughly 100 kph. It works good, that 4.0 has gobs of power, but when cruising, sometimes it will very randomly work bad, just have a misfire hissy fit! It doesn't affect the cruising, but it just works funny.
Its a 1997 Ford Aerostar with the 4.0 OHV, and the E- 4wd with the Dana TC28 transfer case.

5.4L... My truck has a momentary moan / growl / bog down issue. It happens at town and highway speeds and usually when I have cruise on OR when I lightly apply the gas peddle. It moans for a few seconds and seems to bog down then comes out of it and carry's on its way. You can hear it plainly while driving even with radio on. I have a regular muffler on the truck but when this happens, it makes it sound like I have a catback on it.
Things i have done...
- New air filter
- New oil/filter
- New fuel filter
- Ran techron injector cleaner through tank of gas

I have a '06 Mercury Mountaineer, right over 100,000 miles. For the past few months the car has started to make a sound and even produce an "clunk" that I can feel when I am slowing down to come to a stop. It only happens when I slow down to around 3-4mph or slower. The transmission has only around 10,000 miles on it. What could be causing this?

About a month ago my Touareg started making loud rumbling noises at highway speeds. It sounds and feels (it makes the whole truck vibrate) like you're driving on the "wake me up bumps" that are on the shoulder. Some times it last for 30 seconds and other times it goes on for the whole trip. It's driving me crazy; however the dealer can't reproduce the problem so they think I'm crazy. It doesn't do it all the time, however, the only common symptom is it happens at speeds above 65 mph. It has happened when it the car was cold and hot, cruise on and off and variable highway speeds. The transmission was replaced right after I received the car due to a malfunction, so the dealer doesn't think this could be a second faulty transmission.

Just curious about the tires that came from the factory to be noisy and loud when at highway speeds? I only have 1500 miles on the tires, will getting more miles on the tires say after a few 1000 miles or so? Also what is quieter option without sacrificing mpg?

I recently had an oil change and 30,000 mile service at a Honda dealer. Car was running perfectly when I took it in, but now infrequently 'moans'. The low moan usually happens after I have driven the car for awhile, at a stop sign and I slowly accelerate to take off. In SF, there are lots of stop signs! As soon as I accelerate to full speed, the noise stops.
Can happen as often as five times in ten mins or not at all if I am only driving on the flat. Have had it back to the dealership numerous times since, test driven it three times with them and only heard the noise once (with a technician). They cannot find a reason for it and seem to have given up.
The car is a 2009, has 16477 miles on it and is under a Honda Care warranty. I purchased the car in 2012 as a preowned certified Honda and have had no problems with it and as I only drive about 3000 miles a year have had no previous services or maintenance issues.

My truck has grinding noises when i am making turns from a stop or at slow speeds. Also my 4x4 dash light keeps flashing several times both when I am sitting still and when driving. Neither my 4x4 auto or 4x4 high work but the low will work. Trying to pinpoint where I should look to fix them. I did replace the 4x4 control mod as an attempt to fix this.

I have a 2006 Subaru Forester with 115K miles. It's been well-maintained and well-loved.
For the past few months, the brakes have been inconsistently making a dragging/grinding noise when coming to a stop at low speeds (<5mph). It sounds to be coming from the front half of the car - I can feel it vibrating a little near the driver side. We've taken the car in to be looked at three times - each time, the mechanics think they've heard the noise and report there is absolutely nothing wrong with the brake pads or rotors. Twice they reported a shim was out of alignment. After the last shim adjustment, the noise got a little better - instead of grinding, it's more of a dragging sound now. Because the noise is inconsistent, I haven't been able to crack the formula of the conditions that produce it, other than that it only happens as I'm coming to a stop at very low speeds.
Is there something besides the brakes we should be having inspected? Does this sound safe to drive?

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??

The boss has an 08 Sport Trac, V8, 4x4. It has the hard bump when slowing to a stop. I've read here that there is a TSB to reprogram the transmission. Called a dealer in Ft. Worth to schedule appointment. Service guy say there is no TSB. Looking for a copy or number or anything on the TSB?

I have a 2005 Ford Escape XLT 3.0L V6 which I bought 6 weeks ago. It has 103,000 miles on the clock. I mainly use it for going to school and getting around town etc but on Sunday I had to take my parents back. It's a round trip of 230 miles. Weather was sunny. Traffic on the Expressway so a lot of slowing down, stopping, setting off cycles but no issues. On the way home, about two toll plazas from my exit on the I90, I noticed that the engine sounded and felt like I was driving in a higher gear than that required for the speed I was doing (5 mph). It's an automatic (which I'm not used to as I've always driven manual) so I don't make any gear changes but if I'd been in a manual, it felt like I was in 2nd when I should have been in 1st. Does that make sense?
Anyhow, so I managed not to stall at the toll plazas but when I exited, the engine stalled 3 times (twice at intersections and finally when I pulled up outside my house). There is no problem starting the car after this has happened. I called my local autoshop who said to bring it in Tuesday so I didn't drive it Monday. Tuesday morning, it felt exactly the same when I was slowing down for traffic, intersections, turnings etc. The autoshop had it 3 days and couldn't find anything wrong with it. There is no data stored on the computer to show any of this happened and it has driven fine for them when they've taken it out. Beyond frustrated! I know what I heard and felt. Someone mentioned the overdrive staying on but I don't know what that means.

My ALT is making a bad whining noise and when I disconnect it, the noise stops. it also seems to be slowing down the engine if that's possible.
The batt voltage is the same with the car running or stopped. no cell, batt idiot light comes on at startup and goes off like the rest of the warning lights.
This is the 2006 2azfe 4 banger.
I believe its gotta be a diode pack shot. Is it difficult to replace the pack or should I just get a rebuilt one? The Haynes doesn't show how to disassemble the alt and replace anything but I should be able to do it. would I also need to replace the brushes at the same time?

On my 96' Explorer 4wd, 4L V6, auto tranny the front end makes a roaring noise when slowing down from 30mph to stop; no shimmy or shake or any other noise, it has 133K miles on it, original wheel bearings; just wondering if it is wheel bearing assembly and are these pressed on or can you remove them and replace with new assembly fairly easily. Are there any threads with the procedure here.......

Last winter I had a moaning sound in my front end when slowing down to a stop when the temps were around the freezing mark. When it would happen, sometimes i would engage the 4WD and it would go away, and come right back when disengaging the 4WD. I took it to my dealer and Ford's procedure was to re-pack the front wheel bearings. When I got the truck back the weather warmed up and the moaning didn't come back. When this winter started and the cold weather came back, so did the moaning in the front end when slowing to a stop.
I took it back to my dealer again, and this time they checked what I suspected all along, the IWE's for the 4WD (the integrated wheel ends). the seals were cracked, letting moisture and rust formation inside of them. After the IWE replacement, the moaning noise went away. My research has found that this problem goes back to around 2004 on up. If has these symptoms with the 4WD truck in the cold weather, have your mechanic check out the Integrated Wheel Ends. By the way, my oldest son is the Ford tech that performed the repair on my truck, so it was in his best interest that my truck was fixed .

My 1994 Aerostar, with 100,000 miles on it, started lurching at highway speeds. Weeks before this, the airbag light began blinking. The transmission man said it felt like it was shifting into overdrive, then out, then into overdrive, then out, etc.,etc. About this time, the cruise control quit being reliable. Dealership said codes didn't show a problem, "I must be mistaken". Then they said it sounded like a fuel filter.

I have problem with an occasional stall that occurs when the engine is warm and slowing to a stop. I have a 1994 fuel injected E-350 460ci motor home. The engine runs great 90% of the time. When cold or sitting the vehicle will start and idle great. After warming up 5-100 miles occasionally I will slow down to stop, the rmps will fluctuate from 400 to 750 rpm as will the vacuum then die. The engine will start up fine but idle roughly wanting to die again during this period. Once the rpms are above 1000 and put into gear the engine will take off and accelerate great. This stalling tendency will last about 15 minutes (if I stop) then appear to go away and not reoccur during that trip.
At high speed and hill climbing the engine does great. It has occurred once on each of my last 4 trips. I have had suggestions about: the fuel pump, fuel pressure regulator, and possibly the crank sensor. I'm trying to figure the best sequence on working this problem up. It might be tough in that the problem seems to go away after about 15 minutes regardless if the engine sits or is run.A few more notes: the rpm and vacuum are great and steady until the problem kicks in. Last summer a shop replaced: the computer, alternator, spark plugs, egr valve, and fuel filter. I think the parts were just replaced till the problem resolved. The problem (unrelated) seemed to be resolved after the work was done though.

So about 3 days ago I made a long 9 hour drive. No problems at all but I did allow my fuel to get a little lower then I normally do. About eighth a tank had 30 miles left on the digital read out. Stopped and filled up at loves where I always get my fuel. And off I went drove it down to 3/4 a tank and made it to my stopping point. Got in to go about 7 miles down the road and come to a stop sign and slowing down the truck died. I thought crap I forgot to turn off the auto start but never done that before. Stopped and stared truck as normal. Made it to my stopping point again. Headed back to the house and doing on average 55mph and truck surges like it wants to die but doesn't.
Rpms drop below 500 and it keeps going I get to same stop sign and slowing down again doing maybe 25ish and truck dies again as I have my foot on the break. Put in nut and started it right up and drive on home. Today went about same distance. Only this time I started it with key and was doing down other things while letting it run it just dies start it back up and take off get to where I was going and it surged or hiccuped so to say. Again started it once I was getting ready to leave and let it run for about 5 min and it died had the heater on as it was chilly out by the lake. Got in and restarted it and it was blowing cold air and had a diesel smell to it. Wife asked me if truck was going to blow up. Backed out of area and put in drive and made it 80' or so and truck died again doing about 10mph
Checked so far
Batteries checked and both are good
No mods done to it
New ICP sensor and pigtail

1995 3.0L 6 Cylinder Aero, aka the Green Goblin.
I've recently noticed that when I'm running between 50-65MPH the GG can't seem to decide whether it wants to stay in D or OD, I think. It's hard to tell whether or not the transmission is shifting or if it's just the engine revving. I don't have a tachometer but it's almost like the engine is revving /surges and then falls back, sometimes repeatedly. Could this be due to a vac line leak?
History- GG has 167K on it. I recently changed the oil, plugs, wires, distributor and air filter. Cleaned the MAF. Due to a failed AC compressor and low funds, had it removed and a bypass pulley installed. Needs a new pipe & muffler which is on the agenda.

My 1997 4.0 Rear Wheel Drive is making a clicking noise when it is put into gear or when it switches from drive to reverse and vice versa. Sound is coming from the back of van. Does not make noise all the time. Drove 50 miles last night with no problems and minimal clicking. Could it be U-Joints going bad? Or is this a different problem?

First of my truck is an 03, xlt 4.6 5-speed with 82,000 miles. Almost always when i come to a stop i can hear a faint humming that is coming from the engine compartment. There is no pattern or set way that this humming happens, it just comes and goes when at idle. As soon as you put load on the motor it will go away. I got under the hood today and fired it up, nothing, gave it just a little throttle and sure enough here is this odd humming. It is coming from in the air intake. Also while i was under there i noticed that the cable that is right next to the throttle cable is very loose, i am not sure what this cable goes to or if this could be part of my problem
