I have Suzuki Swift DLX 2015 Model.
It was working fine till last week. I got the oil and oil filter changed. During the oil change, the worker broke one side clip of air intake compartment (the place from where you take out the air filter). One side was ok and the clip was not available at that time so I came home without that. I also got my plugs and throttle body cleaned. In last seven days after this, my car's fuel consumption increased too much, doing just 7km/l whereas previously it was doing 13km/l in city.
I became curious and today when I examined my engine, it is giving some strange noise on instant throttle. The sound feels like as if the throttle body is open. Such sort of sound comes when the mechanic opens the throttle body for cleaning and gives throttle with entire air intake system removed.
Any idea about what's wrong?
Thanks
