There is no distributor cap on a Pontiac sunfire, only a coil pack. coil pack is located on the back of the engine.
To change the spark coil pack on a 1998 Pontiac Sunfire with a 2.4 engine, first disconnect the battery. Then remove the coil pack and spark plug. The spark plug should also be replaced with the new coil pack for best performance. Insert the new spark plug, then the new coil pack being careful not to bump any of the many other electronic parts. Then reconnect the battery.
Provides a high voltage to the spark-plugs so that the fuel ignites in the cylinders.

it sounds like you need a new coil pack Or you could have two of the plug leads reversed. I'd check and make sure I have voltage at all 4 plugs before I bought a coil pack.

The Blower Motor Resistor Pack is defective. Replace it.
A malfunctioning coil pack can cause your 2001 Pontiac Grand Am to backfire. The more likely cause is a faulty fuel injector.
