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?

Same on my car: fist 1000 PRM then drop to ~550 as you mentioned.

You've repaired it!
