I just went thru something like this with my Buick Lesabre with 120,000 miles. It ended up bing the ignition control module. I was getting a code of P0300 - Random engine misfiring. There are other reasons like plugs, plug wires, coil, etc. I changed plugs, plug wires and checked the coils and ended up with it ICM. Costs abot $140. It was very easy to replace on my car. It is under the 3 coils on my 3.8 liter engine.
