Why is the Check Engine Light and Temp Light flashing on a 1989 Oldsmobile 98 Regency?

The flashing Check Engine Light and Temp Light on a 1989 Oldsmobile 98 Regency indicate potential issues with the engine management system and overheating, respectively. The Check Engine Light suggests a problem with the engine's performance or emissions system, such as a faulty sensor or misfire. Meanwhile, the Temp Light indicates that the engine may be running too hot, possibly due to low coolant levels, a malfunctioning thermostat, or a failing water pump. It's essential to address both warning lights promptly to avoid severe engine damage.
