On a 1998 Chevrolet Malibu with the 3.1L V6 engine, the ignition coil is typically located
on top of the engine, near the distributor. However, since the 3.1L is a distributorless ignition system, it will have
multiple ignition coils, one for each spark plug or a pair of spark plugs. These coils are usually mounted directly to the valve cover or very close to it.
To be certain, I highly recommend checking a repair manual specific to your 1998 Malibu 3.1L or searching online for images of the engine bay of a 1998 Malibu 3.1L. A visual inspection will give you the most accurate location.
