Answer 2

You need a scan tool or code reader5 to plug into diagnostic port. Most all repair shops should reset it after correcting whatever tripped the code.

The scan tool only removes or reads the CEL (check engine light) codes. If you need to erase the flash memory of your 96's computer after performing performance enhancing work, they you'll need to follow the next steps exactly.

Disconnect the POSITIVE battery Terminal and touch it to ground ( not the battery negative terminal ) for 30 seconds. The engine block or the A/C compressor pump will work as a ground. (This is to discharge the PCM capacitors, which maintain the Adaptive Memory).

Reconnect the Battery Cable

Turn Ignition Switch to the "On" position but DO NOT start the engine

Turn Headlight "On"

Turn Headlights "Off"

Turn Ignition Key "Off"

You may also simply disconnect the battery for at least 30 minutes to achieve the same results.

Your computer is now at factory default settings. Driving it to operating temperature will get it to start learning the parameters of the new parts you installed.
