Hello everyone, I changed my engine and after my car was delivered, I drove it for about an hour and it sounded good not until I got to an idle spot and saw the oil light blink.. once I move again it goes off... I got home safely and d next day I tried again but no light came up until I drove for few minutes and once am idle it comes up... what do i do...please help

 

um, perhaps check your oil level and add some if low.
