    Some parts store still carry the OBD 1 code reader you require. Try Advance autoparts and Autozone. Expect it to cost from $40 to $60. Then post the code here. Or, you can call shops in your area and see if they can do the read for you. Make sure to get a copy of their read if you do. Could be a misfire condition or an o2 sensor code.
