I do have wedge dp fix that I installed couple days ago to quit smoking. I drove the car more than 60miles today and got check engine light.
Read the codes and they are;
2CB9: Oxygen sensor 2 after catalytic converter; signal fixed at rich
2C31: Oxygen sensor before catalytic converter; Oxygen sensor emissions control
2C27: Oxygen sensor before catalytic converter; System Check
2C6C: Oxygen sensor after catalytic converter; System Check

My questions
1) What am I doin wrong except installing DPs
2) Are these Dp fix really works ?
3) Setting is too low or high ?

Thanks for any advice! You guys are awesome
