I have a 2010 corolla s and I started to notice that when I was at red lights with the car in drive my rpm's would drop to around 600 but it would only do it randomly, or so i thought until one day I was at a light and turned the ac on and my rpm's went back up to 800 so I turned it off and the rpm's dropped again, turned on the headlights and they went back up.
View 14 RepliesI think I resolved the idle issue on my 2009 Corolla S with 82,500 miles and Automatic Transmission.
Symptoms:
Idled at between 600 and 800 rpms
Annoying vibration in drive and reverse, no vibration in park or neutral
On hard stops, the engine felt like it was going to die
Turning on the a/c would cause the idle to increase to 1000 rpms and the vibration would go away.
At 82,500 miles, I cleaned the throttle body which was extremely dirty.
Process:
Disconnect the positive battery cable
Remove the top of the air box and flex duct going to the throttle body
Disconnect the two coolant lines going to the throttle body, make sure and have a few old bolts to plug the lines so you do not lose too much coolant
Remove the electrical connector to the throttle body
Remove the vacumn line to the valve cover
Remove 2 bolts and 2 nuts (10mm) securing the throttle body to the intake.
The throttle body does not have a gasket, it is an o-ring which should be fine.
Once you have the throttle body off of the engine, clean it thoroughly with Chemtool throttle body cleaner.
The inside of the throttle body and throttle plate should look like shiny milled aluminum. when done.
Spray chemtool into the two ports where the antifreeze lines were connected. If possible use compressed air to blow out these ports.
Clean the inside of the intake and the mesh screen where the throttle body bolts to the intake.
Reassemble, connect the battery, crank the engine and just let it idle for a good 10 minutes
The 2009 Corolla S DOES NOT have a serviceable IAC. It is riveted on to the throttle body. This is why it is important to spray the cleaner in the antifreeze ports in order to clean it. These ports are the antifreeze bypass ports.
I have a 2010 corolla s 1.8 liter. A couple months I started having a rough idle. It will drop below 600 for a second right at the point of stopping and then raise back up. While sitting at a light it will drop down and shake and then go back up. Had a couple people look at it including Toyota and they say it's normal. It did not do it a couple months ago so I know it's not normal.
View 12 RepliesBasically 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.
View 1 RepliesLately I would be stopped at a red light and my rpms would drop to 600. And when I turn my headlights on the rpms go up and the rough idle stops. Should I check it out if so what should I check? My corolla has 49.5k.
View 1 RepliesI changed the battery this morning in my 2009 Pontiac Vibe GT with the 2.4 and ended up with a rough idle. I was not having any of these issues before the change. How to adapt the throttle body?
View 2 RepliesHaving problems with a ECM and throttle body for 2010 Corolla S? My corolla will idle rough and the throttle body will shut the car down to where it is inoperable. It throws codes and shuts the VVT down. The car currently has 56k miles on it and has been to Toyota 3 times in 3 months.
The first time they say they replaced the ECM, I really don't think so. 24 hours after we picked the car up it shut down again. The second time we brought it back in they said the brake light bulb caused the throttle body to shut down.
It had to go back again this week after it shut down again in traffic when it was idling. Toyota said the throttle body had to re-learn the idle again from when the ECM was supposedly replaced.
My Mother just purchased a 2012 Corolla LE and this thing doesn't have the auto on/off for the headlights on the switch..
How to install the auto switch from a 2010 or if it will even fit and function?
I was installing the footwell lights and now the headlights on buzzer does not work. And when I press the lock/unlock button on the key fob, the corolla actually locks and unlocks the car WHILE the doors are open! Also, the key in ignition buzzer doesn't work as well!
The seatbelt buzzer works though. I don't know what to do and I want those Features back!
What happened is that I was trying to zip tie the led strip on the metal bar under the steering wheel behind the panel with the tire reset switch. I guess the + & - terminals touched the metal thing and there was a little spark! The dome Lights work and so do the foot wells! But the buZZER doesn't!
Searched the forums and found a similar problem for a Solara but not carolla. Have a 2009 Carolla s and the low beam headlights don't work. The high beams work, but when i dim them only the fog lights come on (if i have them enabled, which is how its set for my wife now). If i go to the parking lights mode the low beams will come on. Changed the bulbs and fuses are intact. I am wondering if it's a relay or the column switch. I have access to a multimeter, techstream, and have basic auto skills.
View 3 RepliesWhen your car is idling the rpms drop below 600rpm and you can feel like its going to stall but then goes normal. How do i fix this? Clean throttle body???
Also how hard is it to change the transmission fluid? Possible to do it at home?
I bought these lights on ebay. It was direct replacement for stock and it has Fan and ballast built in. Light is good and all good but im hearing some low frequency humming noise when im inside car and waiting in any traffic light.
I also opened the hood and tested it is there but less. Im hearing more in cabin. When i turn off the lights its gone. Is it the fan ? How to control it.
Subject Vehicle: 2013 Corolla LE
I have a 1993 Base, a 2006 LE, a 2007 LE, and a 2013 LE. All of them Except the 2013 have automatic headlights. That is: you get into the car, start the engine, and drive away with the headlights on. Then later when you turn off the key and get out of the car the headlights are either automatically off or go off soon after.
But on the 2013 the headlights just stay on or off unless manually switched on or off with the stalk switch. Am I missing something here? Why would the 2013 LE Not have this very convenient feature when even my 1993 Base model with zero options Does have it?
I'm new to owning a Toyota. I just financed a 2010 black Toyota corolla S with 36 miles on it from a local dealership after i decided my last car was pretty much a money pit (2001 expedition)...blew the head gaskets, then after that was fixed developed a bad knock...anyhow i just decided i was overdue for a new car. Its a 5 speed manual and at highway speeds (65-70mph) I've noticed the rpms are bit high...like around 3grand. Is that normal? Just seemed really high to me, I really think this car would do great with a 6 speed. Also is the corolla governed? I was on a long stretch of road and i quickly got to 110ish with no sign of a governor kicking in...?
View 14 RepliesRan into a strange situation today. I actually noticed it last week but thought it was due to Seattle's recent surge of hot weather but guess not.
Anyway here are the symptoms of my 2010 Automatic Corolla LE. Upon turning on the car, the needles do their thing and rev all the way and then come back down, I have watched the RPM needle go to below 1 since I've owned the car. Now, it stays at around 1.5k to 2k RPM before going down to below 1.
While parked, or just when I'm at a light, the RPM needle fluctuates and flip flops between roughly 800 rpm to 1k rpm every few seconds. I can hear it happen sometimes.
Because it hasn't happened in 3 years until now, I'm assuming this is not normal. Or is it, and is just regular wear and tear?
The only thing I have in terms of engine mods is the Takeda SRI, and I've had that for about 2 years with no issues. I have a 400W amp powering a pair of focals up front and a 200W sub in the trunk. But I've noticed all these issues when I have the radio off. I've been keeping the AC on 2 for the past week now, could that have something to do with it?
I have a new to me 2009 matrix. I have noticed that the RPMs at around 2,200 when driving in town at 40 MPH then after a few minutes they drop to 1,600. I know I'm wasting gas running 2,200 RPM when driving at 40 MPH so I have started putting the car in neutral then quickly back into drive and the RPMs are at 1,600. I am also putting the car in neutral as I come to a red light or stop sign RPMs drop to around 900.
View 1 RepliesThe LED Daytime Running Lights are at maximum brightness when the headlights aren't on. When I turn on my headlights, the LED Daytime Running Lights dim down drastically. Is there a way to make the LED Daytime Running Lights not dim down when I turn my headlights on?
View 3 RepliesI've got a 2013 Corolla S with an upgraded sound system. Well when the vehicle is running and its in park or stopped and I turn the wheel, the headlights dim. My headlights also dim if I roll up more than one window at a time. I've been slowly trying to narrow down the issue but with no such luck. I have a 1600 watt amplifier and two, 800 peak watt subwoofers.
View 4 RepliesNoticed this morning I was idling at 1000 rpms and was wondering if that's normal or a little high?
View 5 RepliesI have a 2009 Corolla and anytime the car is idling and it drops below 1000 RPMS there is an extremely annoying ticking sound, it goes away when I put it in Neutral or the AC is on because it idles higher.
View 7 RepliesI've noticed the 2013 Corolla has a second+ gap between the moment you press the pedal and the engine RPMs actually rise. Most often, the car jerks as the RPMs rise too fast to keep up with my foot.
In fact, if I press the pedal all the way to the floor and release it quickly enough, the engine doesn't even react.
