I thought about the EGR also and I did look at it, seem to me moving freely, I did not remove it and clean it yet though. But if it were the EGR I should get a low / rough idle in drive without the brake applied or in park. And why would it idle normal in all gear and brake positions when I remove the horn fuse. Its got me puzzled.
I will check the PVC and the EGR again.
Thank you for the ideas.
I'm not 100% sure how to test the PCV valve; however, replacing it fixed all my idling problems.
