I did not. I bought them second hand.

Quick update. I installed my dp fix for my emission test. Seems like the problem is almost non existent now. Wierd. Any idea what that could mean?

Dp fix should not be left on, you're getting altered readings that are masking existing issues.

I don't leave it on. I usually install it for a few days to do my inspection. It's just wierd that it's not doing the STFT problem as much. I thought it might point me in the right direction.

I'm having the same exact issue, did the dp fix still help it from doing that?
