AI4Car quick readA short, original guide from the AI4Car knowledge library.
To understand a high idle just after a cold start, compare it under normal, safe conditions: cold versus warm, idle versus steady speed, and light versus higher load. Record ambient temperature and how long the idle takes to settle. Change one condition at a time so the result stays useful.
Do not create a risky test just to reproduce it. Compare behavior with the owner’s manual and check for an intake hose left loose after service.
