Does low oil affect VTEC?
Low oil = low oil pressure = issues with VTEC engagement. This has been covered before many times.
Can a misfire be caused by low oil?
Either the motor is in fact low on oil or the oil pressure sending unit is not working properly and may be producing a faulty reading. Engine misfires can be caused by many different problems and are generally caused by either a spark or fuel issue or in some cases, a combination of both.
