Hello 

I have a 2007 Toyota Corolla CE 1.8L 16v manual transmisson, 60000 miles no OBD codes with a cheap scanner, 
I having excesive vibration after cleaning the throttle body, after cleaning it started idling very high at 1900-2100 RPM but it lowed to 900 rpm after running the car for 10-20 minutes, but now when the car idles and reaches 1000 rpm aprox. the steering wheel vibrates excesively, on lower or higher rpm the shakes decrease considerably, what could be the reason for this and how do i fix it ? is something to worry about?

Also need to mention that i moved the electric throttle manually in order to clean it, i´ve heard that it might need to relearn the idle but not sure how to that in this car without a fancy scanner.

Thanks for your time
