where is the ignition module

Located underneath the distributor cap or coil pack.

if its a DIS car which stands for distributorless ignition system....which that car should be its located on the front of the engine between the rad and exhaust manifold under the coils you will need a 5.5 mm socket and 4 elbows on one arm to get to it easily.

1992. With the 3.1 will be under coil packs. Closest to firewall if packs are numbered keep in order or the firing order will be your next problem

On engine
