You should replace the spark plug wires on a 1994 Geo Tracker every 30,000 to 50,000 miles, or if you notice symptoms such as rough idling, misfiring, or difficulty starting. Inspect the wires for any visible signs of wear, cracks, or corrosion, as these can affect performance. Additionally, if you've recently replaced the spark plugs, it's a good idea to replace the wires simultaneously for optimal ignition system performance.
