Took a quick 30 second log of my car running open dp at idle. From my research, everything is within parameters but I do notice I always have to fix my ISC position. I know when the fan kicks on it raises but everytime I start the car the position number isn't always at 30. It'll be like +/- 5.

Am I worrying too much or is there something wrong?

Thanks :hellyeah:

No one else has any issues with the ISC position changing? Or have a comment about the idle log?
