Q: How to remove and install the ignition coils and module assembly on Chevrolet Beretta?
A: To remove and install the ignition coils and ignition control module assembly, first disconnect the battery's negative terminal. If needed, remove the cooling fan for access. Unplug the module's electrical connectors and label and detach the coil wires. Remove the assembly bolts and lift it out. Separate the coils from the ignition control module by removing their bolts. If removing the ignition system assembly, disconnect the IOI harness, remove assembly-to-camshaft bolts, lift it off, and detach the housing. Disconnect coil harnesses, remove coils, and then remove the ignition control module from the cover using screws. Reinstall in the reverse order.
