1996 Toyota Corolla P0302 Misfire: Diagnosis and Solutions After Replacing Spark Plugs, Injectors, and Ignition Components
I've been consistently receiving the P0302 diagnostic trouble code indicating a misfire in cylinder 2 on my 1996 Toyota Corolla 1.6L automatic model. Despite replacing spark plugs, spark plug wires, fuel injectors, distributor cap, rotor, and ignition coil, the vehicle still exhibits noticeable symptoms: studdering during gear shifts, hesitation and irregular idle, and occasional stalling. I need reliable guidance to resolve this issue as soon as possible. The P0302 code persists even after multiple component replacements—what should I check next?
A compression test is recommended to identify potential engine internal issues such as worn piston rings or cylinder wall problems, which may be the root cause of the P0302 misfire despite external component replacements.
