Q: High idling

asked by on October 04, 2016

My car is a 2008 toyota vios. It has a high rpm of 4-5k. I had it scanned and it says throttle problem. The mechanic cleaned the throttle and it was ok. The next day it turned out the say problem of high idling. Some saya due to faulty wiring and aircon so i had replaced the wiring and cleaned the AC. They even put an automatic adjuster for the air control. Tried everything but still its the same. Do you think i should replace the throtle body? Thank you
My car has a manual transmission.
