To find out the specific issue, you need to get the diagnostic trouble codes (DTCs) read. This can be done in a few ways:
* OBD-I Scanner: Your 1994 Wrangler uses an OBD-I system, which is different and less sophisticated than the OBD-II systems found in later vehicles. You'll need a scanner specifically designed for OBD-I to read the codes. These are less common than OBD-II scanners, but still available online and at some auto parts stores.
* Auto Parts Store: Most auto parts stores will perform a free check engine light diagnostic. They'll plug in a scanner and tell you the trouble codes. Keep in mind that they might try to sell you parts based on their diagnosis, so it's always a good idea to get a second opinion if you're unsure.
* Mechanic: A qualified mechanic will have the tools and expertise to diagnose the problem accurately and repair it. This is generally the best and most reliable option, especially for an older vehicle like a 1994 Wrangler.
Ignoring the check engine light could lead to further damage or more expensive repairs down the road. Get it checked out as soon as possible.
