You did not mention which engine the car has. If your car has the 4 cylinder engine the ignition control module is below the intake manifold at the rear of the engine. You can follow the spark plug wires to it. The coils are mounted to the ignition control module. If your car has the V6 the ignition control module is near the starter and again you can follow the spark plug wires to it. Again the coils are mounted to the ignition control module.
The ignition module is located under the coil pack. Follow the spark plug wires to find the coil.
Ignition misfires and "sputtering" can be caused by any number of system failures such as air/fuel, ignition and even emissions/exhaust. A failing ignition coil, control module, plug wire and plug are often components that should be examined when diagnosing such misfires.
Catalytic converter due to unburned fuel being burnt in the converter. It can also cause damage to the ignition module.
did you changed your thermostat? You MUST keep around 195 degree thermostat in the vehicle at ALL TIMES due to the computer system. The ignition module usually gets hot due to corroded electrical connections at the ignition module and or the module is HEAT SENSITIVE and needs to be replaced. (plug wires) Ignition misfire can produce a variety of driveability symptoms including hard starting, rough idle, hesitation....
under the ignition coils. it is flat comes off after you remove the three numbered igniton coils. they plug into the module underneath them.
