AOAmy swift 2012 dlx knock on 1st gear specially when lights on or ac on since last 2 months. also decrease pick as i am regular driving the car so feel that thing.oil zic xq changed recently also air and oil filters.
1) Are you hearing the knocking sound?2) Which engine oil you were previously using? Grade?3) Do you hear knocking sound when car is in neutral/no gear?4) At what RPM you usually shift gears?5) Have you been using Hi-Octane as a fuel?
The fault was actually at air filter, not installed properly by the "choty ustad" when i opened the filter box and recheck the filter position it was bended so when i keep that filter on proper position the problem resolved..thanks to all.
for slow pick i think after 40K there is time for tuning.. any suggestion??
yes tuning is needed
