Went to have my car inspected. It failed the emission test. The mechanic said he is seeing Code c1201.

My auto idles, accelerates, and shifts smoothly, however, the engine rpm fluctuates while crusing. The tac will drop 200 - 500 rpm momentarily then return to its original speed. This appears to happen randomly and can occur several times a minute and at any speed. The OBD does not throw a code. So far, I have changed the air filter, cleaned the MAF sensor, and ran through a tank of gas laced with Sea Foam. Any suggestions?

dealership says they see dry rot on the tires but I don't

I noticed my fms indicating around 25 mpg. I used to get around 32 driving back and forth to work, a mile or two less in cold weather. Also noticed my tach was running around 2900 rpm at 65 mph where I think normal was around 2100 rpm. The car has 39,000 miles and it is an automatic. It seems like it might not be kicking into OD. I noticed I started getting poor gas mileage within the last 2 weeks. Now that weather has gotten above single digits, it has not improved.

Did not drive car for over 30 days. Able to jump start car, but with engine on, and car in gear, it does not move. What could be the problem. No problems prior to going away and not driving car.

Must be an easy way to turn off lights. Toyota says it points to a wheel sensor; popular problem. They have not looked at the vehicle.

What is the average cost?

How often I should change my engine n transmission fluid?
Do I have to use TOYOTA oil brand for my corolla?
THank you

I just changed front brake pads with OEM. After being installed I was surprised coz the color of the brake pads is GREEN. Is it true OEM brake pads corolla 2011 is green color? I worry if they gave me aftermarket brake pads instead.

So I called the TOYOTA dealer, and they told me that there are 2 types OEM brake pads, Japanese & American. Is that true? Are they the same?

Thank you so much & I really apreciate your answer.

My Corolla would not start the other morning.It would turn over but not crank.After about 3 tries it fired up and has not given me any other problems.Anybody out there run into this.Toyota said computer showed hard start problem but on code to pinpoint problem.

When the a/c is on, it has a bad smell. I have reported this twice to the dealership since purchasing my vehichle. They have shown me that my air filter is clean. They don't know what the cause is. I live in FL and I feel that a/c is a necessity but the smell is so bad, that I don't run the a/c often.

If it is a timing belt, how often does it need to be changed?

Dear repairpal,

my corolla 2011 s alarm sign blinking all the time. Usually is not like this. I think the alarm is on valey parking mode, even the sound of the alarm when I lock or unlock the door is different.

Do you know how to put back to alarm regular mode instead of on valey parking mode. THank you so much
