I'm gonna say no. PO300 (random missfire) would probaby be caused by ignition, fuel or mechanical failure.
if its on a Chevy then everything! Chev o2 sensors are known to do that you just have to keep changing them, or stop buying chevys.
All O2 sensors are threaded into the exhaust system at various points. Upstream O2 sensors are located before the catalytic converter(s) and downstream O2 sensors are located after the catalytic converter(s).
There are four o2 sensors on a montero sport.
Look to the ECU/sensors or airflow. Check the O2 sensors, air filter, etc.
The 2.5 has 2 O2 sensors (both on top of the engine) and the 3.5 has 4 O2 sensors (two on top, and two under the car).
The o2 sensors screw in. There is a special socket for removing the 02 sensors with a slot in the side to clear the wiring.
All the O2 sensors are threaded into the exhaust system at various points.
The O2 sensors are located between the exhaust manifolds and the cat converter. They screw in to the head pipes. Those are also called upstream O2 sensors and in some vehicles they are also called air/fuel sensors. There are also downstream O2 sensors that are located after the catalytic converter.

mabye the O2 sensors
The 1992 Ford Taurus has two oxygen (O2) sensors. Both O2 sensors are located upstream of the catalytic converter with one on each exhaust bank.
