Isuzu Rodeo left bank engine misfire issue despite new spark plugs and PCM replacement on Isuzu Rodeo

Some Isuzu Rodeo owners report experiencing left bank engine misfire issues even after replacing spark plugs and the PCM. This problem may stem from faulty ignition components, as worn or damaged ignition coils and spark plug wires can still lead to misfires. Additionally, valve cover gasket leaks are common in older Rodeo models and can contribute to engine problems. Some owners also find oil in the spark plug tubes, which can cause misfires; resealing the tubes during valve cover gasket replacement may help resolve this. If the misfire persists, further investigation into these components is recommended, as regular maintenance and thorough inspections can aid in addressing the issue.
