Camry :: 2007 LE - Exhaust Buzzing When Accelerating
Nov 22, 2014
I have a 2007 Camry le 4 cylinder. When under a load on the highway there is an occasional buzzing that occurs when accelerating (sounds like a piece of metal vibrating at a high pitch). It only happens under about 3000 RPMs and the noise doesn't occur any other time (idle, reving the engine while idle, slow speeds, etc.). Today I got it up on a lift and checked all of the heat shields under the hood and around the exhaust under the car. Nothing seemed loose. I had two mechanics look at it and one thinks that the exhaust flex pipe is the culprit, while the other insists that this is a known issue with the resonator (said a small piece may have broken off of a baffle inside and is vibrating). Are either of these components well known to cause this type of issue? I'd rather not replace both if one is frequently the cause.

Recently bought a 07 Camry Se with the JBL system in it. The stereo had no sound and after checking I found that the 25amp fuse under the hood was missing. I replaced it and as soon as the amp received power it started buzzing in all speakers. I was able to stop the buzzing by unplugging the connector on left of the blue connector in the middle of the amp. That connector seem to control the rear deck speakers. I now have clear sound from the front speakers but nothing from the back. So question I have is does this sound like more of an Amp problem or speaker problem?
One more note I also found that the rear trunk torsion bar clip was broken, from what I have read these bars can cause a short on the rear speaker if they touch the speaker would that cause a speaker or amp to blow?

Bought the car used a few months ago with a little less than 72k miles. At 72k miles, I replaced all brake pads. Car now has 75k miles on it. Wife just got back from a 1k mile road trip with it.
I took it for a little ride, and noticed this problem about 3 times, it doesn't happen every time. There is no vibration or anything when slowing down and stopping. But, a few times, when the car was at, or almost at a complete stop, the brake pedal would feel like it was buzzing a little bit, and I could hear a springy sound. I tried to reproduce it with hard braking, but couldn't. Seemed to only happen with slow, gradual breaking, and when the car was just about at a complete stop. Brake fluid is full. No lights on dash. Asked my wife if she slammed breaks at all, or had any problems, she said no. Then she said she experienced what I did once, when she was at a rest area, stopped
The only thing I can think to compare it to is how the brake pedal feels and sounds if you lock up your brakes, and the ABS is doing its thing....which I haven't ever done with this car...

Leaking exhaust manifold? The truck has a much louder than normal "knock" when accelerating. At first I thought and had some bad fuel in the tank. I eliminated that with a full take of good fuel and some STP but the "knocking" continued. Then I thought that perhaps it wasn't firing on all cylinders but it felt like it had full power. I took it to my mechanic and he said it as a exhaust manifold leak. He said that he has never replaced the exhaust manifold but that it was a "nightmare" and expensive. He also said that it's not a safety issue but on the long run the leak would cause the truck not to pass its emission test. He said the problem was with rusted bolts that would be difficult to remove.

I have a 07 Camry LE. I recently replaced the belt tensioner and belt. A couple, maybe three weeks later its having symptoms of hesitation when accelerating and when at a stop. The rpm's are stable but seem to dip below its operating specification, causing the car to come to a wobble felt just like when you're in too low a gear when driving a standard vehicle. I suspect it may be air related but that's just a guess. I have not looked under the hood yet since its dark out and would like to get some feedback on this problem. Another probable cause I suspect is the fuel filter. The car has 113,000 miles and i doubt its ever been changed (I am the second owner).
Before I changed the tensioner I could be a stop and then suddenly press the accelerator to avoid oncoming traffic. The car will stall and die sometimes. It's has only done this to me on two occasions. Both at the same location. Rapid acceleration at this point was on an incline. If it matters.

2007 Camry, I4, 156000km ... For some time now, when i accelerate i hear this faint pinging/rattling sound which sounds like its a pulley rattling or some sort of chain that is loose. It mainly happens when i start from a complete stop and even sometimes when i press the accelerator while cruising. I hear the noise more when the windows are rolled down and it sounds like it coming from underneath/front of the car.
I have changed the accessory belt and checked all the pulleys for tightness and they seem pretty tight, no wobbliness. I have gotten a dealer to check it out, and they told me it was the flex pipe, i had it changed and still hear the noise, this was quite a while ago. Also no leaks from the water pump area.
The sound can only be heard when the car is in motion, and if i put it in park, or N and rev the car there is no sound. I have heard that it could be suspension related and i have had a mechanic check the suspension and he says he cannot see anything wrong. I even tried to run premium gas in the car to rule out engine pinging, and sure enough the noise persists with 91 octane gas.
Could it be related to transmission? I do a fluid drain and fill every 30,000km. And the fluid always looks new and does not smell burnt. How I can get to the bottom of this noise?

This is going to sound odd but here is the case: When accelerating in car from 0 mph to about 10-15 mph there is a noise coming from the rear. It sounds as if it is coming from the axial or something because it does it once every revolution. But the wierd thing is is that it does it louder when it rains or any moisture is in the air!
We had back right bearing replaced. But still makes noise. Don't think it is rock or tire because it only does it sometimes when speeding up. And does it very loud when raining or humid

I would like to retrofit the Lexus LS exhaust tips on my 2007 4 cylinder SE 4 Cyl, only if dual exhaust conversion doesn't have any adverse effects on my car.
Idk much about piping and exhaust systems. Where would the second pipe split from, after or before cat? what pipe diameter? Should the pipe diameter for both exhausts be smaller? Will it affect my hp/torque? Would it be louder or quieter? Any other forseeable effects?

A few days ago I managed to replace the front and intermediate exhaust pipes using new hardware and new gaskets. Prior to this (see my other thread about the rusted flex line), I did get P0137, but that was probably due to the fact the pipe broke before the O2 sensor, giving it a strange reading.
Two days ago after replacing the exhaust with Dealer parts, ensuring everything was tight, and putting the old O2 sensor back, I started the vehicle up, and upon idle, there were no lights whatsoever. Today several minutes after I started driving, I received the check engine light, and with the code reader, came up with the codes P0138 and P0606.
P0138 is O2 Circuit High Voltage (Bank 1, Sensor 2), which is the sensor I removed and put back.
I assume that this sensor needs to be replaced, and I assume that this has caused the P0606 ECM code as well.
Before ordering a new sensor, is there anything else I should check? I did make sure to plug the old sensor back in properly, and checked all the connections on the exhaust to ensure they were tight. All parts were Dealer parts, and nothing else was touched, changed, or modified.
The car sounds, and drives great since the exhaust change.

This odd noise just started today. Whenever i accelerate at any rate, an odd "buzzing" sound occurs. It almost sounds like a diesel... Boost is not holding as it should, and I get exhaust backfires in first, second, and third gear. Makes no noise when i lay off the throttle, only when i touch the gas... I don't have a VAG-com, I'm thinking a exhaust leak or boost leak.

How to get rid of that stupid buzzing noise from the exhaust every time it shifts in higher RPM, It freaking sounds like a Honda and it is driving my crazy. I did the Exhaust flap mod but it didn't go away.

OK, I recently purchased a 2009 Passat 2.0 & love the car with the exception of one thing that's driving me crazy. When slowly accelerating & the RPM's are between 2-3000 rpm there's a loud buzzing noise from the engine. (Sounds like a kazoo) Again, it only happens when accelerating slowly & will happen at all speeds.

When accelerating there is a noise that seems to come from the exhaust (can not be duplicated not in gear). This noise got louder recently, and then the noise stopped. When the noise stopped, the check engine light illuminated as well as the VCS and VCS off lights. Is there a common cause for this and/or trouble shooting steps that should be followed?

I have been searching online for days trying to find out why my car is smoking. i recently broke the oil pan on my 03 vw passat 1.8T. When I broke it I didn't know what had happened and I am sure all the oil drained completely out. The turn off engine now light came on and immediately shut car off! But I am not sure if i did in time before doing any major damage. my husband replaced the oil pan with a new one and everything seemed to be running good. i drove it for about 10 days and i noticed a whitish (I am not really sure of the color cause it was in my rear view mirror and couldn't see well) smoke coming from the exhaust as i was accelerating to get on the highway lasted about maybe 5sec then stopped. it has since done it 2 more times as i am getting on the highway but not every time. There are no fluid loss doesn't overheat when driving it all the fluids are good. I thought maybe head gasket or cracked head but husband says its not. the last it did it i stopped driving it in hopes to find out why its SMOKING!!!

I own a Lancer Evolution X and I've been having a strange issue where, when accelerating around 2500-3500 rpm a thick cloud of blueish smoke starts pouring from the exhaust for about a second or two accompanied by a loss in power. The smoke stops quickly and then it runs like normal. This only happens once in a while for a second or two. When idling there is no smoke. Or at Wot. There is no coolant mixing with oil. The oil was recently changed with the proper oil. and it still happens once in a while. I checked the turbo and there is no shaft play or oil inside of it. There is no loss of boost. Although I did see a tiny pool of oil near the turbo inlet and some more oil coating the inside of the intake pipe. is it possible that the turbo just sucks up some oil that collects at the end of the intake? the PCV line which connects to the intake appears to be letting some oil into the intake.

The car had no accelerating power and it was well overdue for new spark plugs and wires. I just replaced them and it's doing much better, however, the engine seems to be shaking a bit when I start it/idling, which is making the entire car shake some too ( the seats, car shifter, etc ) . It's been awhile since I've also replaced the air filter too, which I obviously should have checked but haven't yet. When I replaced the spark plugs, I noticed there was a minor amount of engine oil on the spark plug wires, where they connect to the spark plugs; more notably the front 2(of 4), left and right. I also just changed the oil and there was no oil loss really, other than any minor amounts that get burned off through the miles.
The exhaust manifolds ( y-split ) are okay, but one of the nuts seems to loosen over time, causing a minor air leak there and makes it a tad noisy. Near the back half of the exhaust system, there some water dripping at one of the connections, and at the tail pipe the exhaust smoke is chugging and isn't consistent sounding.
What is still causing this engine shaking and the chugging noises from the exhaust system. The 'Check Engine' light is on, due to other repairs I know I need to make, such as an 02 sensor and fuel level sensor; however, lately it has started blinking too.

I can smell the exhaust inside the cockpit when accelerating and high RPMs, but in nothing in normal driving. I checked the pipes for leaking but all is fine.
My friend suggested to remove the catalytic converters that might be blocked. the car Mileage is now 145000 KM....
