What did the code reader or scan tool gave you as for the OBD2 code/s

A misfire on a specific cylinder should point you to check the plugs/fuel injectors/compression/vacuum leaks/weak coil/sparkplug wire/s problem.

A random misfire is usually a lean fuel-lean misfire,open EGR valve,fuel pressure low and bad fuel.
