Hello all,

Could you pleae advise.

After cleaning Idle speed sensor (it was very dirty) I found that behaivior of car is changed when I start ignition. Before cleaning, when I started car idle speed was 550 RPM immiediately. Now, after cleaning, when I start car idle speed for few seconds is increased to 1000 RPM and than goes to 550 RPM. Is it normal? Do you have the same on your cars?
