Re: low idle corolla 2006 and vibration when brake

Your engine idle speed is about 20 - 30 rpm below spec. I wouldn't call this a dealbreaker.
(Spec = 650 to 750 rpm)

I know you said that you cleaned the throttle body, but if this car came in for me, that is the first thing I would check.

Your long term fuel trim is at -20. This is a little unusual.

Do you have any accessories mounted on the vehicle, or have any parts been replaced with non-original parts?
What fuel do you use?
Where are you? (elevation, how far south, etc?)

Hi, thanks for helping, if and cleaned the throttle body and nothing more vece improved, including a new maf sensor. if I think the vibration is so because the rpm drop too including when I feel shake when accelerating the fall too, all beginning to change the battery, it tells me that -20 fuel trim long I have some doubts, and read in several places that the fuel ratio sensor car is a bit flawed, but what I'm wondering is because I get the check if you have problems or that I recommend because the fuel trim -20, my car is completely stock no modifications and its support all new .. it is because the -20 I think the problem there walks

I would not use premium grade fuel unless the owner's manual specifically calls for it. Engines designed to run on standard octane (regular) fuel can have many different operating problems when run on premium (higher octane) fuel.
