Pontiac Sunfire engine misfire issue, unable to locate coil pack after changing plugs and wires on Pontiac Sunfire

Some Pontiac Sunfire owners report experiencing difficulties with engine misfires and locating the coil pack after changing the plugs and wires. Many find that the coil pack is typically positioned behind the air intake hose, just behind where it connects to the motor, while others discover it above the axle when the vehicle is lifted. Owners note that faulty coil packs can lead to significant ignition issues, adversely affecting engine performance. Additionally, it is crucial to inspect the wiring harness for any damage, such as burns or frays, as these can further complicate ignition problems. Some drivers have also encountered oil leaks in the spark plug tube, which can hinder the ignition coil's operation and cause misfires. For those concerned about the coil pack's functionality, testing it is recommended, especially since a misfire condition or a 'no-spark no-start' issue may indicate a faulty ignition coil pack or ignition control module. If locating the coil pack proves challenging, consulting the specific model year of the Pontiac Sunfire for detailed guidance may be beneficial.
