    You can get the code read at autozone but if it’s a misfire I’d check your plug wires, plugs and have you recently washed the engine bay or run through water? Sometimes water can get past the boot and cause a misfire by causing a short and not allowing the voltage to reach the spark plug.

    Have the plugs been changed recently? Or within the last 100k miles?
