Hello everyone ~

Recently my car is experiencing an unstable idling when the car is in standing still.

It does not happen a lot , only once or twice in a day. If I may describe the symtom a little more ,

its like when you move your sterring wheel , rpm goes up slightly from 500 to 1000 rpm . Its kind of like this.

My car had throttle body cleaned out recently and doesnt seems to have any other issues. Everything is fine

except the rpm going up from 500 to 1000 time to time.

what could be causing this??? Am I being over sensitive ??
