I have had the p2 sensor replaced and the evap curcut replaced. Now when the mechanic puts the car on the computer it doesn't say fail it says incomplete the mechanic keeps resetting the engine light and telling me to drive on the highway at 55 for a quarter mile then coast down to 20 then take it back up to 55 I've done this for the past week and it still isn't working. What else can I do to reset the computer

If your check engine light is still on there is something wrong. Replacign an O2 sensor and fixing evap shold have fixed it if those were the codes and that was what was wrong. The computer resets it self as you drive the car. Have the car rescanned for codes and see wha they are.
