Lately 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 5 RepliesWhen I drive my 2010 Toyota Corolla on a rough tar road, i feel dashboard vibration on the drivers side. The vibration is sensed in the instrument panel and also around the window. This happens if the tar road is rough or uneven. Is there anyway to remove the top of the dashboard and insulate it?
I live in sunny South Florida, so the heat makes the plastics in these corollas rattle or vibrate more, going over rough tar roads.
I 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 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 RepliesI 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 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 wife's 2009 Corolla S has 107,000 miles. Early on it developed a low idle and vibration while stopped at a light. It was idling about 600 rpm after it warmed up. It never stalled but occasionally vibrated. After doing some research I found some were having success cleaning the throttle body and throttle plate. I did that along with changing the spark plugs. At that time I disconnected the battery to reset the computer. She has put about 2,000 miles on it since then and it never idles below 800 rpm. The vibration hasn't been back either.
I believe it was the throttle body/ plate cleaning and disconnecting the battery that resets the computer that fixed it. The plugs still looked good at 105 K miles, but I had new ones so I put them in. I bought a can of Berryman b12 choke & carb cleaner and sprayed a little on the throttle body and plate and then sprayed some on a rag and wiped down the body and plate. It was quite dirty.
My mechanic just informed me that because of my extreme drop, the drive shafts are at an angle that is stressing the final drive bearing on the transmission. I am leaking very small amount of fluid, he said it might not be a big deal.
View 3 RepliesThe fuel line is fine.
Today after work I started the car in a sheltered car garage and as soon as I started the car the after the initial start up sequence the check engine light stayed on and the traction control light stayed on and right next to it on the left side the "VSC Off" light kept blinking and flashing. I turned off the car and started it several times to see if that did anything and to no avail nothing happened.
While I was driving those lights stayed on and the VSC off light kept on blinking. I also checked the brakes and the brake fluid and they all seem to be fine, I even checked the fuel door as well.
I am not sure what is wrong. I was looking at some of the complaint sites and most people say it happens when you drive through a deep puddle or if it is cold and wet outside. But that didn't make sense because I drove in the snow and those lights never turned on. The only time I used the ETS button is during the snow storms and I drive at low speeds.
I need to know why this VSC off light is blinking? Is it a bad sensor or is the ABS/ETS brake system broken or is it an ECU issue or is it because of an alignment. Since I was told to get an alignment soon.
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 don't know what this rattling is and I've already crawled under the car and see nothing wrong, nothing shaking violently, nothing.
2009 Corolla LE... IDLE will fluctuate from 600 to 900 while at a stop light. It will keep rev up and then rev down to the point where it feels like the car is about to turn off and then it will rev back up again. I use Shell 89 Octane fuel. I have tried everything with the car.
I have cleaned the MAF, the Throttle Body, changed the engine air filter, using only 0W-20 Synthetic oil (change every 3.5 to 4k miles). Have added Fuel Injector cleanered to the fuel: Have tried BG44k, Red Line SL-1, Techron Concentrate. Added Liqui-Moly Ceratec to the engine oil to reduce friction.
Now Changed the Bank 1 Sensor 2 for Oxygen sensor.
Drained the Transmission fluid, dropped the pan, changed the transmission filter and refilled it with the Toyota ATF.
Changed Spark Plugs and used the Toyota OEM Iridiums.
Reset the ECU.
Tires at 35 PSI.
I just recently had an oil change yesterday to be exact. I have never looked at my RPM when I drive, but at every oil changes the dealer always does the "Multi-point inspections", of which I do not like since the tech may ruin something that's not broken or does not put something back together correctly and may cause problems down the road. Anyways, I usually drive at least 80 on the highway. Yesterday I drove home, and I noticed that around 70-75, the RPM was at 3, and a bit over at 80. I've driven other cars and the RPM is never over 3.
View 3 RepliesI had a bud of mine make shims and gave me some negative camber in the back, and in the front, I maximized the camber bolt on my bc coils, this is per alignment stage. when I drive, the car feels a lil wobbly, is this normal? and will alignment fix the problem, or is this just part of the lowered/cambered life?
View 1 RepliesI have a 2011 corolla S. sometimes when i shift from park to drive, it shifts smoothly and easily. most of the time when I am shifting from park to drive, it isn't smooth and doesn't shift easy. You can hear when you move it from park.
View 3 RepliesIt was about 7 degrees Fahrenheit and I started my car and it took a few seconds longer to start then normal but I kind of expected that as it was pretty cold.
Then after letting the engine warm up a little bit I went to leave and the clutch pedal was sticking for a second or two between shifts and I still kind of ignored it and drove home, well after a 45 minute drive by my house it was still doing it.
The next day I drove it to the store and after sitting in my garage for a while it was fine. A few days later, (well last night) I went on a break to get some food and it did the same thing when I left to do that but after it was warmed up to normal operating temperatures it was fine again. When I first started it, the temp was 13 degrees.
I am trying to figure out if there is something wrong with my car or if all of them do that. I am going to stop by the local dealership on my way home today but if it is normal I don't want to waste my time. I just don't like the fact that I live in Minnesota and the temperature is going to get colder then that. I mean what is it going to do then?
I have a 2009 Corolla (smaller 4 cyl) with auto trans. at 101K miles. I have a whine at hwy speed when the drive line is unloaded. What I mean unloaded is there is no acceleration or deceleration. The whine does not change pitch or level with speed.
View 1 RepliesI just bought a 2013 Barcelona Red Corolla S in Manual transmission. Already, I've noticed how rough the transmission is when I shift. But it's only roughy when I first step on the clutch. But if I keep the clutch pedal down, all the gears shift smoothly, until I release the clutch and press it down again, then the first shift is really rough. Especially REVERSE, when I shift into reverse, it's so rough that it shakes the car. There's no grind, just very rough. It sounds like someone cocked a shotgun. Everything is smooth when driving tho, only happens at full stop.
View 14 RepliesI recently bought a 2012 used Corolla LE from a dealer and i've noticed that when I drive at night the lights don't turn on automatically. They daylight running ones are one, but the actual headlights used for night-time use don't come on automatically. I'm able to turn the on automatically by just turning the switch, but I'm just curious why they aren't turning on automatically. I mean they're supposed to right, since its a standard feature nowadays?
