About a year ago I went catless and use the VRSF DP fix. Didnt have any issues until recently when I started getting the codes below everytime I went on a long drive, about 100 miles or so. Any suggestions would help as i am getting ready to sell the car and want it to be right for the new owner. Sometimes i would feel a misfire other times the CEL would just pop up without any symptoms, changing maps even back to map 0 doesnt seem to make a difference.

Is the O2 sensor toast, plugs,or do you think the DP fix is causing them?

29E1 - DME mixture control 2
29E0 - DME mixture control
2C32 - DME Lambda control
2C28 - O2 sensor 2 pre-cat
2C6C - O2 sensor 2 post-cat

DP fix isn't meant to be left installed. It will screw up your O2 readings. Remove it if it is still installed.
