Hello, if there is a weak spark when testing, then replace the coil. Weak spark will cause misfire codes and it will eventually cause the Catalytic Converter to fail. So, it's best to do a coil now before that happens. I'll put up a guide to help
The ignition coil on this vehicle is controlled by an electronic ignition module which is usually bolted to the top right side of the engine or the distributor in the engine compartment, The right side being the passenger side. There is also a cam position sensor (or pickup) inside the Distributor that signals when the spark should occur. The module, pickup and coils will all eventually fail, so if there is still weak spark after replacing the ignition coil, you may have to replace the Distributor and Ignition module as well. They only last so long and this vehicle is 23 years old. So, if it hasn't been done yet, it's best to do all 3. That way you won't end up stranded somewhere. Replacing the Ignition coil and the ignition module is easy, but the Distributor is a bit more difficult, it has to be put in exactly where it came out, and then the base timing needs to be set afterwards. So, if you have never done that before, you may want to take it to a shop for the Distributor section. If the ignition timing is not set correctly with the correct procedure the vehicle will either never start or run extremely badly, potentially causing damage to the engine.
Here are the instructions for replacing the ignition coil. It looks like the ignition module is bolted right to the coil on this model., So that makes things much easier.
There are also a couple of guides below, one is for checking ignition spark and the other is for checking fuel pressure. Remember to change the Fuel Filter every 15,000 to 30,000 miles, which will save on fuel pump failures.
