Welcome to the forum. The check engine light is one to tell you to check the electronic monitoring of the engine. Now most autoparts will scan them but our cars are getting so old some stores don't have the equipment or knowledge no more.
Now need a scanner or do it this way.

These connection are near the brake master cyclinder. I found it easier to have one person to count the flashes and another write it down. Then you can see the code. Unsure if 91 is 2 or 3 code. I think once you count them will be able to find out. Post back what codes and more advice will be given. That way not buying parts that are not needed.
You can buy a code reader for around 40 dollars and be easier to do. Maurice
