Sometimes, just a little bit of carelessness can create major problems with your Pontiac spark plug wires. The wires could be improperly fitted or attached to the spark plugs. When installing wire sets, make sure the connection between to the spark plug and the cap is secure to avoid ignition problems. Often, the diagnosis will show loose terminals. That can happen when the plug wires are mishandled during other kinds of car maintenance operations. It is easy to accidentally tug on the wires, disconnecting or loosening them at their boots. So when you need to disconnect your Pontiac spark plug wires, be careful! Do not pull on the wires, but grasp the plug wire and gently remove it. Use special pliers for this job, if possible. Do not do this when your engine is cold, since the connectors will become looser in hot conditions. Be aware that poorly designed Pontiac spark plug wires can be a major safety hazard that can interfere with the throttle cable linkage, causing the gas pedal to stay open, or resting on the exhaust manifold, which would cause the wire to burn.
