Car details: Optra 1.6L VGIS engine, Manual transmission.
Problem: Since last 2 days, engine rpm remains at 2000 Rpm at idle.
Saw the forum talking about cleaning the throttle body or Idle Air Control Valve.
How to do and also know which is IACV?
The service station even without seeing the vehicle said MAP sensor or Throttle position sensor need to be replaced? Is that required?
