That is a code for 'Front O2 sensor open or short.' This could be as simple as a loose or bad wiring connection at the front O2 wire harness, a problem with one of the fuel injectors, an intake air leak or even low fuel pressure. If you are having higher than normal fuel consumption and smoke at exhaust, possibly the O2 sensor is dead. The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. If you're confident with working on your engine, change this sensor, if not -best take it to a reliable place and have an engine analysis.

The check engine light stays on when the engine computer has detected a malfunction and set a trouble code.
The OBD II code P0134 indicates a problem with the oxygen sensor circuit for the upstream (pre-catalytic converter) oxygen sensor in your 1997 Chrysler Cirrus. Specifically, this code suggests that the sensor is not providing a valid reading to the engine control module (ECM), often due to a malfunctioning sensor, wiring issues, or a vacuum leak. It can lead to poor fuel economy and increased emissions if not addressed. It's advisable to inspect the sensor and its connections, along with performing any necessary repairs.
