Hello.

I have problem with idle at Skoda Felicia 1.6 GLX.

Problem starts about after one year when i replace throttle body.

Usually high idle is present when outside temperature is high, about 30 to 35 degree celsius and the motor is cold.

Now these days when temperature is drop i still have problem and is even worse.

It goes up to 2500 RPM when the motor is cold.

Sometimes when cold start is normal when i drive some kilometers it starts again and idle keep holding for about 2000 RPM.

Sometimes the motor was cut off during low speed and warm motor, but this fault is gone now.

What can cause this idle problem?

When you replace the throttle body did you use a scan tool (OBD scanner) for possible error codes?

Have you checked the coolant sensor? It's wires-contacts?

The vacuum hose is checked?
