I have an 05' Corolla S with 61,000 miles. I went to start my car last night and the car instantly jumped up to 6,000-7,000 rpms. I at first thought that maybe my foot was on the gas rather than the brake. I immediately turned the car off. I checked to see if my floor mat was in the way of the pedals. Nothing being in the way and my foot on the brake I started my car again. The car instantly revved all on its own between 6,000-7,000 rpms and stayed there on it's own until I turned the car off. I turned the car on and off a few more times with the same result. I have no idea what to do and any tips would be great. I did have my car serviced at Toyota a few weeks ago for the solenoid D electrical that was under recall for hard shifting that my car was experiencing.
You may need another ECU (assuming the fix for the solenoid was a new ECU). That is quite unnerving. A few things first.
You should video record this happening from start up to tach position and film the pedal position and post it on here. You say it his 7 K RPMs? Do you hear it hit the rev limiter and bounce off of it? If you do not hear it hit the rev limiter, shut it off immediately and document all conditions. There is no direct mechanical throttle cable, it is all electronic.
The pedal issue did not effect the corolla. Can you grab a picture or write down the part number on the ECU, it is located under the glove box in the passenger foot well? I wonder if they replaced it as they said, as the new ECUs have different part numbers than the old, or the new ECU is bad. Did you get a letter for the ECU recall? If you can try to take a pic of the gas pedal, the side of the pedal that has the part number and manufacturer on it.
After you document and video everything, you should take the video to the dealer if you can and see what they say.
If you cant get it there try this:
turn key to on position(do not start)
depress the gas pedal for 5 seconds(floor it)
turn key to off
release gas pedal
Start the car and see if it made a difference. If that didn't work, check the gas pedal for debris or blockages (with a small mirror) and if it feels "normal" and that it is not binding. Maybe something fell in there. If you are feeling ambitious, you can remove the clamp on the tube that comes from the air filter box to the engine, put the camera down and aim it at the throttle body and turn the key to on (not start) and see if the throttle body opens when the key goes to on. You will need a number 3 philips screw driver or a socket and ratchet to remove the clamp.
If that does not work, disconnect the battery for an hr.
If that doesn't work, you may need a throttle position sensor, which is quite rare, way more rare than an ECU. Any check engine light on when the car is running? Anyone you know have a code reader or a scan gage II?
Keep us posted.

My 06 Corolla S has been doing this for the last 4 years. I was told I was crazy at first when I took it in the first time. They also told me it was the mats and to remove them. I did so, and it still did it. It is intermittent for me. I have hit 100 mph and 7,000 to 8,000 rpms at some points. I can always tell when it is going to do it because the car downshifts and then there is a click and it does it. It does it even if there is no cruise control on for the drive.
The day I drove my car home from the ECM recall, it drove like never before. It didn't try to "click over" like every other time. Then on Monday my car did it for the first time in a while in a new place (it used to do it around certain areas of my drive). It hit 6,500 rpms and braked this time. It did it again this afternoon on my way to work. When I checked to see if the mats were touching the pedal, there was a good 7 or 8 inches between the mat and the pedal. There is absolutely nothing touching the pedal. Still, I am told I am wrong because my Corolla isn't in this recall of randomly speeding up. I am glad to know I am not the only one experiencing this.
Although yours is in park and mine occurs when driving, it's very unnerving regardless.

I already had the car towed to the local Toyota Dealership... the thought crossed my mind to take video but I did not. They are not fixing it yet, they are only checking to see what the problem is.
The tow cost $75.00 and just to have them check out the problem is costing another $115.00 I have no idea how much a fix is going to cost now.
When I called Toyota and explained the problem (prior to bringing it in) and told them that I had just had my car serviced there for the other recall, the rep immediately stated that Corollas are not included in the acceleration recall.
I fear I'm going to be screwed here financially and that I'm going to be stuck with a car that may or may not accelerate on its own.
I don't recall hearing it hit the rev limiter, however I was able to give it gas and the tach did go up another 1000 rpm or so (from 6k to about 7k)
I also did not notice any difference in the "feel" of the gas pedal.

Your engine can't rev to 8k Rpms to begin with. I doubt it's going as high as 7k. And if it's been doing it for four years like you claim your motor would be toast.
Toyota just left me a voice mail and they are recommending a gas pedal replacement...You're thoughts?
Other than the recall that I had fixed a few weeks ago I've had no problems with my car. I've kept up with maintaining the car well. To me a low miles six year old Toyota needing a gas pedal replacement seems odd.

Isn't your car drive by wire? How would replacing a gas pedal solve this problem, assuming you are sure nothing is physically causing the gas pedal to be mashed down when you are having this problem?
I just called them back and they said something doing with the pedal is bent and they have to replace the whole gas pedal. I asked what could cause this. He said he talked to Toyota and they said someone with big feet could have driven my car and somehow kicked up in the the pedal area and bent something. I am 5' and wear a size 6.5 shoe. They said I'm looking at about $500 for parts and labor. I'm pretty pissed off but am stuck with a car that isn't drivable.
Wow they must of really bent it. Not sure if I buy that one, someone wanted to harm you if the pedal was bent, that doesn't happen by accident. Pedal costs $230 so that leaves about 3 hrs for labor to remove and install. Bullshit.
Ask them what is really going on, then insist on getting the bad pedal returned after they are done with it. That $230 price for the pedal should be close to what you will pay. Make sure it is not a lot more than that. It should look similar to the pedal below.

Sounds like a bunch of bs. A bent gas pedal should not cause intermittent revving on its own and it is even more bs that they would suggest you pay $500 for that. I am wondering if something is wrong with your throttle body.
Thats the thing... they literally worked on my car two weeks ago and now i have a bent gas pedal? And their excuse is "someone with big feet" stomped on it? What proof do I have that they are the ones that damaged it though. I'm stuck here I think.
Also, to be clear its not intermittently revving... its constant. Like, I turn the key and it instant;y shoots to 6k and stays there until the key is turned off.
This is very frustrating. I need my car so I had to ok the repairs. I'll ask for the damaged pedal back, however now I'm not so sure they won't just intentionally bang it up more just to say "see?"

That is correct.
The 1ZZ-FE fuel cut off is at 6400 rpm so technically it is impossible for the engine to rev up to 7000 rpm.
