Camry :: 2002 - Whistling Sound From Engine (Not Ground Or Engine Speed Dependent)
Jul 28, 2012
I've got an 02 Camry with the 2.4l 4, it's got a whistling sound from the engine that isn't ground-speed or engine-speed dependent, it's triggered by specific throttle positions...
Because of this, I'm 99.9% sure it's simply air whistling over the throttle plate at certain angles (my old 88 ford station wagon's throttle screamed like a banshee when the cruise was set to 78kph on level ground) but I thought I'd ask in here in case any variable cam timing system or something that can cause similar noises.
The noise has been there as long as I can remember, but it made me wonder the other day when I had my windows down (been trying to limit AC use to save fuel unless it's *really* hot) and heard it reflecting off passing traffic; Wouldn't Toyota have noticed something that loud and done something about it in an engine design?

I have an 03 Camry LE with 80,000 miles I do all the maintenance myself it has had the alternator replaced once at around 40,000 miles. The problem that just started is a whistling sound that ONLY is audible after 2500 rpm at acceleration. When the car is in park no matter how much I revive the engine I can not get it to make the whistle sound it ONLY can be heard at acceleration after 2500 rpms.
Also once I cease to accelerate it goes away while I'm driving there is NO Whistling. I've read that it could be the alternator so I had it checked twice on the car and it checked out good it passed all tests. I've removed the belt and spun the pulley to listen for bad bearing but to me sounded fine. I've removed the throttle body boot and checked for cracks an found nothing also cleaned throttle body (not that it needed it) while I had it off.
Also checked air box and nothing. The only thing I've done recently was take out cabin air filter to clean and replaced it but there was no problem with that. What's puzzling is that it ONLY occurs at acceleration after 2500 rpms then stops after acceleration.

Does this look right? Seems like a hose (like PCV) is missing. Could this be the source of the whistle I hear when the engine is hot?

My first VW was a 2001 4-door Golf (Silver), traded to 2003 GTI (Silverstone), traded to 2006 Jetta Wagon (Blue). Then the wagon was traded for a SUV. Well last week, I have decided to pick up my 4th VW. It's a 2012 CSG 4-door GTI.
After driving the car for a week, and putting on 350 miles, I heard a high pitch continous "whistling" sound from the engine. Took the car to the dealer this afternoon. Tech came out and loosened the coolant reservoir. I heard a "pooof", sound of air build up. The tech said VW is aware of this problem. Something to do with the water pump bearing. It has to be replaced. They took the car in to replace the water pump.

I have Camry 2002 LE which has 110000 miles on it. After last winter in Pittsburgh, first time I drove it for 200 miles continuously and all of sudden the engine started making very loud sound after 2-3 hrs drive and I had to pull it off.
When you give more gas, the sound increases even further. It is very load and unbearable. I called AAA and mechanic advised something wrong with engine and I cannot drive it anymore so have to tow it.
The sound is coming from engine and it is very very load. I will take it to mechanic tomorrow but what would have gone wrong. Is it the end of my car life?

I've noticed during the winter my 2012 6.2L engine seems to 'whistle' when it is cold. It also seems to do it intermittently...that is, it always whistles when cold, but it might stop for 30 seconds and then do it again. It does it at idle, and also when driving, just until it warms up.
What is it, and do other people's trucks here do that? I was thinking maybe the engine fan, but why would it cycle on and off for maybe 30 seconds. My other thought was A/C pump.

I have a 2002 F250 with 189,000 miles. Im having some very bad issues that im trying to fix. The truck idles rough, with fluctuating RPM's. In certain speed reanges it also shakes and runs rough. If I turn the overdrive off the shaking pretty much stops, but it still accelerates pretty slowly. There is also a whistling noise from the front of the truck until the engine warms up, someone told me it sounds like a bad intake manifold? Does that sound right? What could be going on with my truck? All spark plugs and coil packs have been replaced, as well as the fuel injector rails.

Speed-dependent road noise, mildly pulsating roar as though I were driving a truck, just keeps getting louder as the weeks go by. Completely independent of load. Accelerating, decelerating, coasting, disengaging clutch, has no affect on volume or pitch of noise. Volume and pitch increases with speed. At 20 mph it is noticeable. At 80 mph it is quite annoying. Seems completely independent of road surface.
Rear wheel bearings were replaced about 50k miles ago, and they feel fine.
Front wheel bearings feel perfectly tight.
Replaced all four tires with new Michelin Defenders. That eliminated a low speed whomp-whomp--whomp that turned out to be a cord separation in the front left tire, but otherwise had negligible impact on the road noise.
Changed fluid in transmission and rear end. No change at all in the noise.
I thought that the only thing that would be speed-dependent but load independent would be the driveshaft carrier bearing. I bought a new one, but when I put the car up and exposed the driveshaft, I found that the rear U-joint was bad. Didn't figure the U-joint was my noise, as that would be sensitive to load, but needed to fix it. U-joints are not serviceable so I ordered rebuilt driveshaft which came with a new carrier bearing. Put that in today. Absolutely no change in the noise.
Tranny tail shaft bearing felt tight when I was replacing driveshaft, and no sign of oil leak from there.
All four rear CV joints feel tight, and in any event, noise from those would be load-dependent.
I have been searching the web, and rear shock mounts are often mentioned as possible suspects for road noise, but people rarely post what their problem turned out to be, and I would think that noise from failed shock mounts would be very road surface dependent.

My mom drives a 2002 Toyota Camry with a 2AZ-FE engine and 180,000 miles on it. Recently she started hearing a rattling sound coming from the engine. She says the sound does not go away after the engine has warmed up. I took a short video of the sound. How to go about diagnosing the issue.

I took my 2007 (manual!) Honda Civic LX to a local car shop last Friday because it wanted its oil change, oil filter change, tire rotation, and spark plugs etc. checked. When I got the car back, I drove it around for a little while and noticed a noise that is periodic and speed-dependent -- as in, the frequency goes up when I am going faster and slows down when I am going slower.
I've since checked the air pressure and while one tire was a little low, the tires are all at the right pressure now, and the noise hasn't gone away. I also feel like there is more vibration in the steering wheel now than there used to be. I think the sound is coming from the front driver's side, but I'm not sure about that.
Obviously I should take it to the car shop and give the guys the what for, right? But what should I be asking them about? What could have happened? It also happens to be the case that on the 4th of July, someone backed into the front of my car with a moving truck and a couple of parts on the front of the car needed to be replaced. But I had

I have an 01 Ranger 4x4 that recently started to make a loud speed dependent noise from the drivers side front wheel, a quick jab to the right on the steering wheel and it stops, straiten out and it comes back...since I know my shocks are worn and have some cupping on the front tires my first thought was tire noise so I moved the back tire which is evenly worn to the front and no change, next I removed the tire and checked everything visually.
All seems ok, the brake does not seem to be dragging and there is no evidence of a cv problem, everything seems tight, so I'm guessing the problem is a bad wheel bearing? If I grab the tire at 12 and 6 there seems to be excessive movement from top to bottom, there should be none right? If memory serves any movement is indicative of bad wheel bearings? I guess I'm looking for some vindication before getting a new hub?

I am having an issue with my 2002 GTI 1.8T. I have tried searching for an answer to this, and found a couple things saying maybe it could be the secondary air pump but wanted to get more opinions before I go shell out money to chase this problem.
When I start up the car in the morning after having it sit overnight, the car does the normal thing where it increases rpm's to about 1100 to warm it up. During this a loud "whistling" noise can be heard. Once the car is warmed up a little bit, the rpm's decline to about 900, and the whistling sound goes away. When this happens though it almost sounds as if a valve or something is closing causing the noise to go away.
Also, I am unsure if this is related to this, sometimes when I am driving, I will be accelerating and the car seems to stop accelerating as strong as it was, boost goes down from around 8 or 9 psi to about 4 and I seem to lose power as if I had let off the gas some. When I put my foot further down the car accelerates harder again and boost goes back up.
I have already changed spark plugs, cleaned MAF sensor, and run the 3m 3 part engine cleaning kit through it.

I have a 1999 f250 SuperDuty with a nasty vibration That begins at about 70mph. The truck is an extended cab 5.4l Manual trans 4X4 with a one piece driveshaft (No mid bearing). The Vibration appears to me to be a driveline vibration that is speed dependent. It is the same in gear, out of gear clutch in or out. I have replaced the wheel bearings/hub assemblies on all four corners, completely rebuilt and balanced the driveshaft the driveshaft, removed the front driveshaft, put brand new tires mounted and balanced on all four corners, new clutch, had the flywheel turned and balanced, and replaced the transfer case output bearings. Pinion bearing feels tight and does not leak.
Also the Input in the trans felt tight when i had the trans out. The truck had the vibration when i bought the truck and still vibrates after i have done all of this work. i did not change the motor mounts because they looked fine. when i bought the truck the tabs on the extension housing holding the trans-mount to the trans were broken so i make a huge "exhaust clamp" to straddle the trans and bolt to the trans mount.
After driving the truck up north last weekend the truck seems to shake going taking of at lower rpm as if the motor mounts and trans mounts are bad. I guess my questions is can a bad trans mount, motor mounts cause this Vibration at highway speed. if so is there a way to fasten the trans-mount to the extension housing without replacing the extension housing. If not what else can cause this issue?

Today in the morning it was slightly cold so I turned on the heat in my car. The fan started making a loud whistling sound and in about 2 minutes it stopped. Is this a sign of a bad fan?

So I noticed when it started getting cold that my Jeep emits this extremely high pitched whistling sound and I can't figure out what's going on. I've taken it to two mechanics and both said it was a belt that needed to be replaced so I had the belt replaced and the noise persisted. I've noticed a few things about the noise, it only happens when it is approximately 30 degrees outside or lower; only while the car is idling (when I accelerate the noise goes away immediately); It only happens after I've gone above approximately 30mph; The noise will go away after I've gone through a series of idling and accelerating; and stops immediately once I turn the car off. The Jeep is almost up to 150,000 miles.

My wife's 2002 Jeep GC has just started having the problem of stalling at speed. Happens without warning and will start back up with out any signs of trouble. No CEL. Car has a 6 cylinder with 130k miles and is well maintained. Have been reading around this forum and have seen a few people post similar issues. I will look at the connection at the ECU tomorrow. Is this a common area of trouble?

I have an 08 Camry LE, 65k miles four cyl where the engine stops at low speeds. This occurs when approaching a stop or upon acceleration from a stop. No warning, shaking, tach movement engine lights, at all. Engine just dies. It starts up right away. Considered bad gas, so refueled with no difference. Had the car interrogated by two separate Toyota dealers with no resolution. Nothing recorded they don't know what the problem is.

1. engine light always keep flashing when driving.
2. low idle speed <500 at any gear except "Parking".
3. gear "D" at stop, start, reverse, accelerate around 50 mph, whole dashboard was vibrated
action made:
1. "dogbone" motor mount was broken and has replace brand new.

2000 Crown Victoria, 207K miles, 111K on current engine
My car has been an absolute champ since I took ownership of her at 133K miles, and to this day runs trouble-free. However, it's just started making a noise that's got my scratching my head. I can only describe it as a "puff" sound. It's consistent with engine speed (higher RPM = faster puffs), and seems to get louder the more open the throttle is. If you let off the gas and coast, the noise goes away.
What's kinda confusing me is that the noise does not occur at all while the car is not in gear. If you park and rev the engine, the noise doesn't happen at all. All fluid levels and conditions are good, and there's been no loss of power or other issues from the engine or transmission.
My only guess is perhaps I have a teeny-tiny pinhole leak in my exhaust somewhere. The sound seems to be coming from somewhere very close to the engine, but since it doesn't happen when parked I can't pop the hood and look around for where exactly the sound might be coming from.
