I have a 2009 Corolla XRS 5 speed manual and it has started to idle low (sometimes), under 600 rpm and i know that's not normal... I bought it brand new and it has 75k miles
View 12 RepliesIt's a 2012 Corolla. I disconnected the battery and the 2 grounds where the fender mounts in the front. I did this to do some body repairs. When I reconnected everything, the car started, but immediately shut off. What is wrong? Is it a computer issue where it needs to relearn?
View 5 RepliesSo driving home today cel came on and vsc started flashing.
The codes I got were pretty out there
P0420 - cat converter (this one I did expect)
B0cc0 ???
C3a32 ???
U0a8e ???
B3e1f ???
I'm wondering if this was poor communications between the unichip and ecu? As for the vsc flashing, people complained about this during rain. It is currently raining. But not certain this is the issue.
2009 Corolla XLE. 88K miles. My Corolla hadn't been driven for almost a week. This morning the car wouldn't start. Upon turning the ignition key, there was no clicking though. I tried to jump start it multiple times with no success. I thought maybe I am doing something wrong with the jump start.
Called Roadside assistance. The guy had me try to start it once and kind of figured out what was wrong. He started the car and pumped the gas at the same. The car started. He said the vehicle is fuel injected since it has been sitting at the same spot for almost a week. He suggested I should let it run for sometime. Its pretty cold here today (~35F real feel). Since this happened, I started the car multiple times throughout the day without pumping the gas and it did start without any issue.
I am pretty sure its not normal for this car as I never had to do this before. Is there something wrong with the car? Do I need to take the car to the mechanic and have it checked? What should I expect in terms of any mechanical repairs? I dont want to get stranded somewhere and would like to get it fixed.
I just recently purchased a 2009 Corolla S Automatic. It still runs fine, but my concern is that when I start it that there is a squeaking or screeching like a belt is not tight enough or is too tight in the engine somewhere. That and there is a rattling that sounds like a bunch of marbles bouncing off of metal or as if there is something loose that is metal and just making vibrations from the way the engine is running. It drives fine, I have no other problems. I still have amazing gas mileage and everything else. What could be the issue and could I fix it from home?

My mother's 09 Corolla XLE just started making this high pitched noise.. It makes this noise every other day, then it makes a loud pop sound and goes back to normal..
So I've had my car for just a little over 3 years and it has 28,000 miles on it. I always use Shell gas and fill it up before it goes under the quarter tank mark every time. I take very good care of it, and I've loved it. I constantly get upper 30 mpg in city driving and mid to upper 40s on highway.
Recently, I have had an issue where for the past week. One morning, it started rough and got bad mpg for a few mins until the engine "burped" (best way I can describe it). Then it was fine.
I felt this same surge or "burp" 2 times after that. It doesn't speed up or anything, the RPMs drop for a second and come back up as if something is pulling power away. I still get amazing gas milage (39.2mpg and I filled up 2 days ago). It just surges. I don't understand. I take very good care of it! I looked online and apparently its an issue that some others are having. What could it be?
Driving home yesterday and my dashboard battery light started flashing intermittently. This morning it came on and won't go off.
So far I have...
1. Tested alternator and battery with a multimeter and the results appear to be within normal ranges.
2. Pulled out the alternator and had it tested. It went through 7 test cycles on the bench and passed all of them.
3. Swapped out the battery with a new one.
4. Checked the charging system fuse.
5. Thoroughly cleaned the battery cables.
6. Cleaned the battery to chassis and engine to chassis ground cables.
The battery light stays on no matter what I do. What am I missing?
i own a 2010 corolla s with only 3000 miles on it. it is a 5 speed and the other day, when revving out 3rd gear to 5500 rpm, my motor started missing, and my check engine, vsc, and trac control lights came on. i turned off the motor and then started it back up and it ran fine but the dummy lights stayed on. i took it to the dealer and they check the codes and it showed that cylinder 2 missed. after explaining to them how it happened and taking a service technician for a ride, they took off the valve cover on my motor, and seen that 3 rocker arms had FALLEN OFF and they tried making me pay $700 to fix it because i was "over revving the motor". I was told that the rocker arms cant withstand that high of rpms and they will fall off due to the floating design "not bolted". but after 2 hours of arguing, they said they would cover it, but only this 1 time. I don't understand why they have the rev limiter set at 6,300 on these cars, when the rocker arms are capable of coming off at 5,500.
View 14 RepliesJust bought a used 09 Corolla LE with 89K miles on it. I noticed a subtle rough idle when I come to a stop light and especially noticeable when in reverse. Here are the things I've tried so far:
- TB and fuel system cleaned at Instant Valvoline
- Cleaned the MAF sensor with a MAF sensor cleaner
- Replaced the spark plugs with OEM plugs
- Replaced air filter
- New water pump
- Bled the coolant system
I also took it to the dealership and had them checked the PCV and the timing chain tensioner replaced. And of course their response was they couldn't replicate the problem. They also said if there's anything wrong with the O2 sensors, the IAC or the TB system, it will throw an error code. So they basically charged me about $100 to tell me there's nothing they could do and just put up with it until the check engine light come on.
I have a 2010 Corolla S with 130k miles and started developing what felt like a slight misfire at idle. Dealer suggested change the plugs and if not that try the coils. So I got the wrong plugs givin to me there 5/8s not 14mm. I found a socket that worked and thought the old ones where the same as the new ones.
The 5/8 socket fell right in and knew it wasn't the right size after the plug wasn't tuning. Then I searched and found out there 14mm plugs. So now the socket is stuck inside the metal tube that goes into the head. I tried a locking extensions, long needle nose, hook with a slide hammer, pb blaster, heat, crc freeze off. Even tried spinning it as pulling up with an impact.
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 RepliesMy 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.
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.
View 1 RepliesThere is one thing that i find weird, i hear a noise that sounds timed grr grr grr grr when the car is at idle. moreover, i hear this grr grr grr noise after the car has been driven for a while, when the engine is cold, I do not hear anything. also this timed grr grr grr noise is only heard from inside the car, but it is definitely coming from the engine area. the sound comes and goes, performance has not changed but the sound is really bothering me every time I stop at a light. i do not hear it while the car is in motion or while accelerating only at idle. Is this the water pump...
View 9 RepliesA few weeks ago when I started my Matrix(Automatic) it fired up then shuddered and stalled. It did this two more times. The fourth time as soon as I started it I give pressure on the gas pedal until it stayed running when idling. I was unsure if it was because I parked in a garage overnight when it's normally parked outside. It didn't happen again after that so I wasn't extremely concerned.
Today while driving I had a scary incident. I was waiting to turn in an intersection and went to accelerate before another car came through and the car lost power and almost stalled. I was a bit panicked in the moment but I don't remember hearing the engine rev and didn't have power. I released the pedal and when I pressed it the next time it accelerated. I'll check exactly how many km there are but I believe it's around 124,000.
Does this sounds like a fuel pump problem? I had to have my transmission replaced around 100,000 because it was clunking and I would have times I would lose power to my wheels while highway driving.
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 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 with 32k miles, automatic transmission. I have an intermittent low idle issue when it rained or when it is below freezing 32F. It happens when I am in drive and about to brake to a complete stop. The idle dips to around 500 rpm, the engine shudders and the car shakes then after a second or two, the engine idle goes back up to 800 rpm. There is no engine concerns at any other speed just at idle. I have no CEL codes. The engine never stalls. Low idle when braking.
View 1 RepliesI have a 2009 with the 2.4L, 130Kmiles. I have engine shudder at idle and upon deceleration only. No check engine light so no codes-ran a hand held scanner no codes. Cleaned the MAF with MAF cleaner, pulled the spark plugs/coils and swapped them around- still getting shudder and no check engine light. Only thing I noticed is the spark plugs were dry to very wet with oil going right to left. Car was parked on level ground. I am completely stumped.
Other thing is I just got the car back from the dealers to fix the clock spring airbag recall, and the vsc light popped up on the drive home. I did call them but afraid the car will not make it there and my wallet might go on a severe diet after. Out of warranty and dealer said if it is their doing because they knock something loose while fixing the airbag clock spring there will be no charge otherwise it's 129 just to look.
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.
