Toyota - Corolla :: 2006 - Blower Operation Makes Idle Drop
Feb 8, 2015
2006 Toyota Corolla , 100k, manual transmission. Good maintenance, I know the car. The owner told me that the use of the highest setting of the blower motor will cause the engine idle to drop. I stopped-by his place and he started it up, engine was already warm due to recent use, he then turned on the heat, went through the blower settings. I watched the tach and saw the engine rpm drop by almost 300 when he turned it to high. Recent battery and cables (Summer 2014).

247,000 miles on '98 Toyota Camry as of last summer, car owed us nothing. Suddenly lost oil a month after regular oil change, ruined engine. Mechanic found used engine from totaled car (w/ approx 65,000 miles). Current problems:
1. speedometer/odometer not working,
2. heater/blower stopped working this week, blower makes a LOUD, HIGH FREQUENCY sound, sort of like a siren.
Was hoping to get another 2 years from her considering recent cash outlay. The mechanic couldn't figure out issue #1, and he hasn't looked at it since #2 started this week. I guess we can live w/ issue #1, but #2 has to be fixed ...

My 2000 corolla has consistently gotten 35 MPG until last month, suddenly I've dropped to 18-20 miles per gallon, a friend suggested fuel filter fail, but i can't discern if it has an external one...

My Corolla was purchased new, and at 29500 miles it started getting a strange vibration (not the steering wheel but the car itself) whenever going up a hill or at higher speeds on the highway but ONLY when the gas was pressed (You once you let your foot off the gas at the same speed the vibration stops). After three attempts of taking the car to the dealer where the vehicle was purchased, the only responses I got were "We cannot duplicate the problem." After about the 6th time, I drove the car with one of the Sales Managers because the Service Manager wasn't there, and that manager felt the vibration, the dealership kept the car for three days, after which told me nothing is wrong, and returned the vehicle to me. I then turned to Toyota Headquarters, who set me up with a case and a case worker, and all he told me was to try working with another dealer. I went to a second dealer (closer to me house), and they did several inspections and doing a rotation, balance, and alignment.
They said the problem was unknown, but that they RECOMMEND that I get four new tires, thinking that MIGHT solve the problem. I bought 4 new tires, and after getting the tires replaced, and balanced and aligned AGAIN, the problem continues. The Toyota dealership then told me that they don't know what the problem is, and now I'm out of options. I don't know where else to turn, who else to speak with, and what else to do. I already paid off 2 years of the finance on my car, and have 2.5 years left. Side notes (whether irrelevant or not): The day I bought my car my mother got the same exact car just a different color. Her car now has 20000 more miles than mine, and runs beautifully. My car on the other hand, besides the vibration issue, seems like it has less power and has a very difficult time accelerating, unlike the other Corolla.

The air conditioning blower motor stopped working this past summer (worst timing ever). I took it out, put it back in, and it worked again for a day before dying for good. So, I ordered a new one and replaced it. The replacement was working fine for about 5 months, but it then began exhibiting the same problem as the original: it wouldn't come on until after I'd been driving for a while. The new unit never made any unusual noises while running (the old one got noisy just before I replaced it), but now it isn't coming on at all. I find it hard to believe that the replacement blower motor has failed after only 5 months. What else should I check?

I have an 05 corolla XRS. I just had a sport clutch put in about 1 year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop about 500 and I lose power for about 3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this.

2012 Corolla S 5 speed manual. Just bought the car in September. CPO with 19k miles on it when purchased. Now it has 22k miles. The "problem" is as follows:
After driving the car around for some time, meaning fully warmed-up, when I come to a stop at a light the engine's idle speed will slowly drop from about 800 (where it's as smooth as glass and I can't even tell the engine is running) to about 650-600 and there's a noticeable shudder in the wheel and in the whole car. It lasts for a few seconds then the RPM goes back to normal - just as if it's correcting itself. This happens with nothing running except the radio. No fan, no A/C, nothing.
The only thing I could think is that the radiator fan is kicking on and causing the alternator to work harder? Considering this is a manual is it safe to rule out any kind of transmission issue?
I didn't notice it when I test drove the car, and honestly, the car I was driving before made so much racket that this Corolla sounds like a luxury car by comparison.

For about a year now, my trusty Sienna has been making this intermittent little squeak. It's not loud (it's not the belt!). It seems to be coming from the passenger side, toward the rear. It only happens when I am moving. It seems to happen when I am running the AC. It is a soft little chirpy-ish squeak, about 2 seconds in duration. It sounds for all the world like a vent opening up with a squeak. Driveability is in no way compromised.

Lately my Sienna makes this noise whenever it is started. The noise lasts for 5-10 seconds. It builds up very loud towards the end and then stops abruptly. I made a recording of the sound and have attached it.

I have a 2007 gs 350 awd with about 98k miles. I recently started noticing this strange vibration whenever i stop at a red light. I would describe the vibration as a shiver of some type where the RPM kinda drops. After the vibration, I started noticing my car using a lot of force on the freeway and giving me very low mileage. I did some research and changed the motor mounts, and cleaned the throttle. This slightly fixed the vibration but cleaning the throttle fixed the low mileage/using extra force when driving at high speeds. but the vibration still seems to be a problem. Also, does the exhaust possibly have any role in the vibrations?

I own a 2004 Toyota Corolla and the idle seems to be off. How can I fix that? And approximately how much would it cost me?

When I start my '03 Corolla its idle speed is around 1200 and later after driving for a few miles it settles down to around 700. Other than that it starts well and runs smoothly. I tried to back off the idle adjustment screw and found out that the screw was barely touching the stop. In older models I used to be able to fix or repair the cold idle in engines with a carburetor, but am totally clueless regarding fuel injectors. This condition also happens when I start the car during the middle of Texas summer (100+ deg).
The car has 123,000 miles. I have not ever changed the plugs, but as i mentioned the engine starts and runs smoothly. As expected, the idle speed responds well whenever the air conditioner is turned on. The engine temperature comes to the mid gauge as always after driving a mile or so. No engine check lights come on. The car always passes the annual smog inspection.

I have a 2000 Corolla with about 147,000 miles. At idle it runs very rough, but can accelerate up to about 50 mph. Then it starts to cough and wheeze and run roughly again and won't accelerate any further. It feels like the engine will shake itself off its mounts, so I slow down and stay under 50 mph. I replaced spark plugs and a repair place hooked it up to a computer. They then told me it needed about 1800 dollars worth of repairs to replace the valve cam I think they said. I'm skeptical and wonder if it just needs a tune up, . It has not had one since I bought it at 128,000 miles, and II don't know how long it had been prior to that.

I just recently purchased a used taurus and was experiencing rough idling and misfiring during operation. I replaced the EGR valve, the egr sensor, coil pack, spark plugs, iac valve, as well as check for vacuum leaks near all the hoses. I am a novice when it comes to this, but I was able to change those without issue. The misfiring was fixed during driving, but I still have rough idling. The needle seems to stay in check pretty well and the check engine light isn't on, but the car kinda hesitates and it causes the car to rock when idling. You can also feel the stuttering and rocking when cruising at very low speeds (5-15mph). I've already plugged in a decent amount of money into parts and am running out of patience when it comes to fixing what is a "potential" problem, and it winds up not fixing much.

Basically when the car is in D and when i am stopped with the brakes pressed on at a stop sign or a red light, the car starts vibrating and i can see the the rpm going down and then receiving back up and going down again something when the car is in R. its a 2009 toyota corolla le 90k miles. when the headlights are on, the rpm stays high so the car does not vibrate or anything. other than this the car runs perfectly fine.

I have a '98 5-Speed Corolla. If I rev the engine when the car is in neutral and warming up I hear an odd grinding noise when I let off the gas and the engine goes down to idle. The noise does not occur if I put my clutch in. Is this something to worry about?
Also, I'm wondering what CV joints sound like when they're failing.

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).

My exhaust system was replaced on my 2005 Corolla in August. After driving it for just a few days, there was a shaking when the car idled. The mechanic replaced two engine mounts and the idle was much worse! He said it was ok to drive, so I started on my planned trip across the country. In Denver I took it to a mechanic at the Toyota dealer and they adjusted the throttle. It was better for a while, maybe a week and 1,000 miles. Now it is worse than ever! Having gotten two totally different causes from mechanics, I am not sure what to do next.
Also just before the exhaust sytem went, I had the 60,000 mile service done and had the car totally checked out by both Toyota, and an independent mechanic who specilizes in Japanese cars. After a car wash in California, the maintence required light came on.
What is going on?

Mine is toyota corolla - 2001 VE model. It has 116K miles in it.
It hesitates nowadays to pickup after a long idle time, say in morning when i start to work or when i leave from work to home(idle time of 8 to 10 hrs). I noticed this problem only during very high temp, say atleast 80F.
Hesitation will be there for 4 or 5 secs and will not move even if i give full acceleration, but after that it moves normally.
Car has automatic transmission and i only see this i put it to Drive(D or D2) and not when i do reverse.

I purchased a used 2010 Toyota Corolla LE with about 40k miles back in February of this year. Since then, the car has been issue-free and has responded accordingly.
Two weeks ago I noticed that the car when idle or at a stop light it'd make a subtle rattling noise (as if it was something behind the glove compartments rattling against metal). At 1st I thought maybe it was something inside, but as that week turned to days, I noticed that while I was outside the car and it was on and idle, I could hear the rattling from the right side of the car under the passenger seat (closer to the engine, as if right below where the glove compartment sat)--It is a constant rattle at the same frequency..meaning it doesn't rattle one way 1st and then another later. It sounds the same, but it is random.
It evolved from a subtle rattle inside to being a loud rattle outside under the car. I noticed that if it was rattling and I turned off the air, the rattling would stop, but after 20 seconds, the rattling would return just not as frequent.
It was advised to me that perhaps it was the blower...but the blower sits behind the glove compartment and should not sound so loud under the car. Not only that, but if the blower isn't on (when I turn off the air) it shouldn't sound...at least that's my logic for it.
The sound is getting louder and more frequent at this time and I'm just not sure what to do about this. I live in Miami, FL and hearing so many rip offs at mechanics, I don't know what this rattling is and I've already crawled under the car and see nothing wrong, nothing shaking violently, nothing.

I have a 1993 Geo Prizm (Toyota Corolla) that idles roughly and lopes only when the engine is fully warmed up to operating temp. I changed the plugs, and wires are only 1 year old and seem to be in good shape. I suspected a vacuum leak, but have not been able to find one.
