Without knowing the code it is very difficult to adjust the defouler. You are essentially just guessing and going the wrong way will make it worst. Most autoparts stores will read your codes for free or you can pick up a cheap OBDII scanner on amazon for under 20 bucks. We put a lot of testing into our defoulers. A random one from another company most likely wont work.
P0420 - Turn defouler out 1-2 turns.
P0139 - Turn defouler in 1-2 turns.
Make sure you pull the battery after each adjustment to clear your emissions trims.
