My mother in law signed over a vehicle to my 23 year old daughter last year before she died of cancer. My daughter had been one of her caregivers, but this gift has been costing me - registration, needs to be smogged, insurance, check engine light with no codes showing with OBDII reader. Apparently the instrument cluster was replaced due to a broken speedometer but check engine light was not connected right. So check engine light is consistently on, but no error codes. Problem is check engine light can be an auto fail of California smog.
