Toyota - Corolla :: 2003 - Idle Speed Settles Down To Around 700
Dec 9, 2012
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.

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 1998 Jimmy SLE 4.3L is having issues starting. The vehicle will start but then stop when it settles down to the idle rpm. When i turn the key I get a fuel pressure of around 52-54psi and i can hear the fuel pump running. The odd time when I can get the vehicle to run I get a fuel pressure of 55psi and the engine runs better than it ever has. Since the problem started I have changed the following:
Cap and Rotor
Spark Plugs and Wires
PCV valve
Fuel Filter
No codes showed during a scan and the problem occurs often but occasionally it will start without a problem. My last thought it would be a fuel pump or a fuel pressure regulator. Again, I can hear the fuel pump activate when i turn the key and the fuel pressure is just below 55psi when i turn the key.

I filled up my car three day ago and ever since then its been shaking when I brake and when I speed up and pretty much any time the car is moving. Why its doing this I just had it in the shop two weeks ago for a full check up. What the issue could be?

95 corolla, 260K trouble free miles.
Lately when the car is just "rolling" low speed about 5 mph, occasionally when I give it gas it kind of "slips"...the engine revs a bit but the car doesn't accelerate right away. It's like it's caught between 1st and 2nd. (It's an automatic).
Is this a sign the transmission is slipping? I do go up a very steep hill every day (my driveway) and I shift it into L to do that...I go up at about 3-4 mph or so for 40 yards or so. Maybe this is wearing it out?

I bought a 2011 Toyota Corolla brand new and the last several winters in the snow the traction has been terrible. Even at very slow speeds, it is difficult to get the car going and keep it straight on snowy roads. I have a 2007 Corolla also that was bought new and never had these similar issues with that car. The current tires on the 2011 car are Bridgestone Insignia SE with about 20k miles on them. But even with less miles, traction has always been an issue.

I have a 2001 Toyota Corolla 5 speed manual that is having a hard time picking up speed, but the engine will rev as high as your willing to push down the pedal. The engine runs well its just not affecting the speed of the car very quickly. We replaced the MAF sensor recently and it made little to no difference.

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?

I have a 2011 Corolla LE with the automatic transmission. When traveling at a constant highway speed (i.e. 60 mph), the tachometer will start jumping around. It will jump up than down by anywhere from 200 rpm to 1000 rpm. It only lasts a few seconds then returns to normal. The dealer is saying that is just the electronic controlled transmission selecting the correct gear. I have never heard of this in any other car.

Early 90's Toyota Corolla.
I've been hearing this sound the past couple weeks coming from the rear of the car. Not related to the rpm, only occurs if the car is moving slowly -- like when I'm driving in a parking lot, looking for a space. Occurs when turning, even slightly, but not when going dead-straight. It it intermittant, seems to occur more often on hot afternoons, never heard it all winter, or even now in the morning. Not that loud, but noticeable. Sounds a little bit like a vibration, sort of a buzzing sound, but more musical than a simple buzz.
The best way I can describe it is that it sounds almost exactly like that sound they make in kids cartoon shows on Saturday morning, when something bad happens, like one of the characters get hit on the head with a baseball bat ..." waah waah waah" .. sort of like a muted trumpet or muted trombone.
Rear wheel bearings? Brakes?

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.

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.

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.

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.

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).

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.

Just noticed the other day when when rolling up or down the window on my 2010 corolla, when the window reaches the upper / lower stop and the switch is held down, the idle speed drops and the engine stumbles. Alternator ?

My son's 2010 Toyota Corolla S made a "rattling ticking sound at idle" twice this week.
I can't duplicate it, the oil level is fine and everything is working.
