If your Chevrolet COBALT exhibits idle wobble, weak acceleration, MIL, or rough idle on cold start with high fuel consumption, this typically indicates worn ignition coils or internal breakdown leading to insufficient ignition energy. This ignition coil converts low voltage to high voltage and delivers to spark plugs for reliable ignition and smooth engine operation. OEM number 25190788, also compatible with 96983945 high-voltage pack; for 4-cylinder Chevrolet COBALT engines. When installing, disconnect the battery negative terminal and ensure coil-to-spark plug connections are tight to avoid secondary faults due to poor contact.
