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 ??

A simple test will verify

Thank you alan !!

By the way could it be the bad mass air flow sensor?????????????
You can easily check by disconnecting both of the MAFS electrical connectors. If your idle smooths out, it's
time to replace both of them.

Regards,
Alan
