Toyota - Corolla :: 1990 - Idle Speed Increased For Some Reason
Over the past month I've notice the idle speed increasing. Yesterday I had to turn the idle adjustment screw to lower the idle speed, as the high idle speed was making it difficult to drive in stop and go traffic. Especially if I took my foot off the gas while in gear, it would jerk rather than slowing down smoothly as it used to. I think the jerking was related to how the ECM stops the injectors completely when slowing down in gear, to improve mpg, then before the rpms gets too low, fire the injectors back up again. Anyway, lowering the idle speed with the adjustment screw fixed the jerking problem, for now.
But in 20 years, I've never had this occur before. The only time I've fiddled with the idle adjustment screw was during tune-ups, and then only had to adjust it 5-15 degrees. This time I had to turn it in 45 degrees. I expect there is unwanted air getting into the intake manifold somehow. And it will probably get worse. Here's some ideas -- in order of most likely to least likely -- I've had what could be causing it.
Throttle valve sticking in throttle body and needs a cleaning.
Throttle linkage needs a lube.
Canister purge valve is open during idle and allowing fumes from the canister into the intake manifold, when it shouldn't be.
Throttle position switch has failed.
Vacuum hose or device leaking.
IAC valve (part of throttle body in this car) is sticking.
ECM is bumping the idle speed through the vacuum controlled actuator (VSD). Unlikely, b/c the idle speed still increases when I turn the headlights on or I turn the steering wheel, both of which use this mechanism (I think).
Thermostat -- unlikely as it happens even when the coolant has reached 195 deg F (when the fan turns on).
Toyota - Noises :: 1990 - Rubbing Sound Coming From Under Hood When Cold
My awesome 1990 Toyota Pickup (6 cyl., supercab), fondly named Ol' Rusty, has a measly 245,000 miles on it and still running strong. The one problem is that when it is very cold out such as this morning (-10F), I get a terrible noise coming from under the hood just in front of the steering column. It sounds like a belt rubbing, but I can't find it. It happens when I start going faster than 20 mph and goes away once the engine is completely warm. When it's happening, the speedometer jumps a bit. Interestingly, if I warm the truck up for 10 minutes or more so that the engine is completely warm, it still happens when I first drive the truck. Is this something I need to worry about or can I continue to ignore it like I have been for the last 3 years?
View 2 RepliesToyota - Corolla :: Groaning And Creaking Noise Coming From Right Front Wheel Well
I have a 1991 Toyota Corolla Wagon (150,000 miles) with noise coming from right front wheel well. My car is making groaning and creaking noises like the hinges of an old wooden door. CV joints serviced <5000 miles and the boots are clean and intact. There is no clicking noises during a turn Left or Right. Bouncing the right front corner does not replicate the sounds, tho' there is some slight squeaking noise not heard from the shocks/struts in the other corners. The sound is NOT heard in the morning going to work, but is very noticeable driving home at 5pm. I notice the sound going downhill at 35 mph, but goes away with light braking, Going over railroad tracks does not affect the noises. I'm thinking this could be worn bushings, strut mounts or who knows what?
View 1 RepliesToyota - Corolla :: Noise Coming From The Rear Of Car And Tire Cupping
I've had some noise while doing slow turns for the past 9 months or so, seemingly coming from the rear of the car. It's sort of a rrrrr ----rrrrrr -rrrrr noise, but it has a slight buzz to it too, like something is vibrating. It's hard to say which side it is coming from. It only occurs when turning to the right. But recently it sometimes occurs when going straight, but slow, like when approaching a stop light. Braking seems to have no effect. The other symptom is the left rear tire has very definite cupping. There are easy to see flat spots on the surface of the tire. The tire isn't perfectly round in other words, but more like an alternating sequence of flat spots. The other 3 tires don't have this cupping, they show a normal wear pattern.
I jacked up the rear of the car and tested each tire to see if I could detect anything wrong. I pulled, pushed, twisted. I could detect no play at all in either tire. I spun the tires by hand, and there was no unusual noise. They both just spun quietly, freely, with no apparent wobble or anything unusual. The service manual says the rear wheel bearing is bad if there is 0.2 mm of axial play. I doubt I could have detected 0.2 mm of play the way I did it, just pulling on the tire.
The only other thing I noticed is that the (rear) toe-in adjustment is different on the left than on the left. By this I mean the eccentric bolt-gadget is set on different marks on each side. The right one looks like it is set to have more toe in that the left. The right one is 4 marks positive toe-in, the left is 1 marks positive toe-in. I'm assuming these marks are just for reference, and don't represent the actual toe-in, just that's the setting it took to get the rear wheel alignment correct when the car was built.
Do I have a rear wheel bearing problem? A rear-tire alignment problem? Something else?
Toyota - Corolla :: 2007 - Squeak / Creak Coming Seemingly From The Rear
It happens most often when the going over bumps and uneven roads, I tend not to hear when going over potholes (probably because the sound of the crash over potholes tend to overpower the squeaks.) It sounds like it's coming from the rear right-side.
So, it must be the suspension then, right? You would think so, except:
It sounds like it's coming from inside the car rather than outside. Since I have the windows all rolled up, the squeaks would have to be pretty loud for me to hear it, if it's coming from outside.
Did the bounce test, pushed it with most of my weight to hear if it makes any sound. It doesn't.

Toyota - Filters - Damage - Mechanics - Corolla :: Slight Sound Coming From The Engine
Yesterday I took my 2006 Toyota Corolla for an oil change at this small shop. As I drove away I heard a different slight sound coming from the engine, but I thought it could not be possible, since I had just left the mechanic and I had no previous issues with my car. I stopped at a store for about 15 minutes, then I drove a couple more miles when, suddenly, all of the engine lights turned on, the car felt weak and died. I checked the oil and it was totally dry, not even a drop to wet the napkin I used. I called the mechanic, he came over and added oil and an oil filter.
He claimed that the filter burst, is that even possible? Since I hear a strange sound the moment I left his shop, I tend to believe that he failed to put it in. What do you think?The main problem now is that my car engine is making this kind of click clack sound. I called the owner of the shop, who is the brother of the mechanic that worked on my car and I told him that I am taking my car to be diagnosed at Toyota today. If there is damage to the engine, which it sounds like, how can I get these guys to pay for it?Is it safe to drive my car like this?I am very dismayed at the whole situation and really stressed. I need this car to last me another good 5 to 6 years. I am the original owner. How to handle this case and the possible mechanical issues at hand now and down the road.
Toyota - Corolla :: 2009 - Constant Rattling Sound Coming From Water Pump Area
Recently blew the belt that runs the water pump, etc while on a vacation. Had to leave the car at a small mechanic in Winthrop, WA. He replaced the Water pump which had gone bad and the belt that shredded. The car ran beautifully for a week. Now there is this constant rattling sound coming from the water pump area. I attached a video with the sound. The sound will quicken as you accelerate. At cold start up it is usually not present then starts a couple of minutes in.

Have this issue after driving on a steep climb? My first oil change is coming up soon and I'll mention this for sure with my dealership. I checked the web and the forums here and nobody have seem to mention it yet. I have an auto transmission by the way.
Passat (B5) :: Grinding Sound Coming From Rear Of Car At Low Speed On Turns
I'm experiencing a grinding sound that seems to be coming from the rear of the car. I can't tell if it's the tires wearing or it's something else, it's especially prevalent at certain speeds and on a curve..........
I can hear it when going slow and proportionality the grinding is slow... as speed up it's faster and at certain speeds it's quite loud...........it there something besides the rear tires that could be causing that, rear axle? something needs to be lubed?
At first i was sure it was the tires which are turanaza's and they have gotten louder (I think) as the mile have accumulated, but now I'm not sure since i can hear it at low speeds on turns.
Nissan - Altima :: Creaking Sound Coming From Left Front Wheel When Go Over Speed Bumps
I've noticed a creaking sound coming from the left front wheel when I go over a couple of particularly large speed bumps. I have had a lot of problems with the suspension in this car, and have replaced the front struts, the front right control arm, and the sway bar links and bushings. My best guess is that this noise is coming from the front left control arm, as it has not been replaced, although my current mechanic says that the front left control arm is fine. Also, it has been under 10 F here the past few days, so this could also just be a result of the cold weather.

View 1 RepliesCorolla / Matrix 2009-13 :: Unusual Rumble Or Grinding Sound Coming From Driver Side Front Wheel Well
I noticed while driving my car there was a unusual rumble or grinding sound coming from my drivers side front wheel well. I get out and look I see a bunch of Fluid all over my wheel well. I look around turn my wheel around and see this fluids all on my rotors and suspension. Ive noticed couple weeks back the boots on the struts were ripped in two pieces from deteriorating or dry rotting (this was on both sides) and ive also been hearing some odd squeaking sound for over 15k miles every once in a while going over big bumps or train tracks. Struts go out at only 80k miles on their corolla? Yeah struts do usually lose their life around 60-80k miles but I've never seen them leak around that many miles. Is this a common issue?

View 4 RepliesToyota - Matric :: 2011 - Squeaking Coming From Rear Wheel When Turning
Vehicle: 2011 Toyota Matrix XR 4-door hatchback
A few days ago I noticed that my car started making an odd, very noticeable squeaking noise. The noise is coming from my rear left-hand wheel. It's audible from outside the car, and from inside with the windows down.
The wheel makes a squeak each time it turns, so the frequency increases with higher speed. It's audible from ~15km/h, below which the squeak is barely audible, up to ~70km/h, above which I can't hear it any more, maybe because of wind. It makes a slightly different kind of squeak from the same spot when I'm backing up. There is no other noise of any kind (nothing unusual is heard with the engine on, and the car stationary). There are no other problems at all with the vehicle. It's been about 4000km since my last oil change, I have that coming up soon, but I doubt that is the cause of this, since it's coming from the wheel.
What caused it - my theory is perhaps a pothole or running over a speed bump too fast. Any way, this doesn't seem like that big of a problem, so maybe I could fix it myself. What this could be, or how I should approach this?
Corolla / Matrix 2009-13 :: Drove With Handbrake Engaged - Creaking Sound Coming From Rear
The issue is I drove a few km's with the handbrake engaged in my moms 2nd gen matrix. I reasoned that it was showing me the exclamation mark and beeping to tell me the fuel was REALLY low, so I assumed it was going so hesitant to go to save gas...............
I drove a few km's slowly, and when I got to my street I stepped on the gas as a "hell yeah I made it", only to come out the car to see the rear brakes smoking all over the place.
Only about 20 minutes after I came home I realized what happened, (don't even ask what my reasoning for breaks smoking was this time) went and disengaged the handbrake, but now about 5 hours later I just saw my mom leaving in the car and there was a slight creaking sound coming from what seemed to be the rear.
Could the handbrake being engaged for another 20-30 minutes after the breaks getting so hot from all the friction potentially WELD the drums to the other part of the brakes? I hope I didn't mess up the wheels or the parts they are sitting on.
Toyota - Camry :: 2009 - Popping Sound In Right Rear Wheel Area?
I have an '09 Camry and for the last few months have been hearing a metal popping sound in the rear wheel area when I go over a bump or pothole unevenly or backout of a driveway at an angle to go onto the street. The sound does not occur when the wheels when they are even, only when the rear right wheel is "lower" than the left. It has not been in any accidents and there was no event that preceded this popping.
I took it to the dealership but they were unable to replicate the issue but it happens no matter who drives the car (my husband or myself) and it is likely that the service guys didn't go over any bumps/curbs/potholes unevenly to hear the sound. What this is or if this is in need of getting fixed? They check the axles and said everything was good with the car but it is still popping and driving me nuts.
Toyota - Corolla :: 1990 - Fuel Gauge Rises After Starting The Engine
On my early 90's Corolla, when I turn the key to "on" but don't start the engine, the fuel gauge will -- for example -- read 1/4 full. It will stay at 1/4 indefinitely as long as the engine isn't running. Then when I start the engine and drive the car for a few minutes, I notice the gauge has gone up, so it will be reading 3/8 full within 5 minutes of driving. And I don't have to be moving, once it gets to 3/8, it says at 3/8 whether moving or idling at a stoplight. It has always done this, even since the car was new. It's not a problem, but I've always been curious what causes the fuel guaue to rise like this.
