Lexus Repair: 1993 400LS, computer scanner, filter change

Question
I recently took my lexus for an oil & filter change. A couple of hours after oil change, the check engine light appeared on...Could this be oil change related where should I start diagnosis?

Answer
Hello, The first thing you will need to do is take your computer scanner and hook it up to the OBD2 diagnostic plug and extract the engine codes. Then just cross reference the code in your engine code book. Of cource if you are not equipped for this you will need to bring it to Lexus to have it diagnosed. Hope that helps.
