Just tried using that method to check for the codes and it didn't work. My friend even tried who already knew that method and he couldn't get it to work either. Once the check light comes on while the motor is running it will stay on until the car is shut off. We tried with the car still running and with it off, even though the light isn't on with the key at the IGN position.

Got my dowel the other day but it turned out to be the wrong one so I went back and got the right one and the o-ring. Going to install it right now and see if I have any luck. Thanks for the responses
