Re: How to reset check engine light on 2000 olds...
Use a code reader or disconnect the battery NEGATIVE (not the positive!) cable for 5 min's. The best way is the code reader as you will loose all learned programming in the engine control computer and this can cause idle problems. Autozone will do this for you free.
